Pipe Relining and Drain Repairs NSW 2026 - Complete Pricing Guide

Pipe Relining and Drain Repair Costs in NSW for 2026

Pipe relining has become the default repair method for damaged residential sewer and stormwater drainage pipes across NSW over the past decade, and with good reason. It avoids the disruption, cost, and property damage of excavating through driveways, tiled bathrooms, landscaped gardens, and established paving to reach a damaged underground pipe. The cured-in-place pipe (CIPP) relining process produces a structurally independent liner inside the existing host pipe that seals every defect simultaneously, creates a smooth bore with no joints for root re-entry, and carries a structural warranty from most reputable NSW contractors.

The decision between relining and excavation is not always straightforward, and it is one that deserves careful analysis rather than a default recommendation in either direction. Relining is not appropriate for every damaged pipe, and excavation is not always the expensive last resort it is sometimes portrayed as. Understanding the CCTV findings, the pipe's geometry, and the access conditions for each specific situation is the only reliable basis for making the right choice. A contractor who recommends relining for every job without viewing the CCTV footage deserves the same scrutiny as one who recommends excavation for every job without considering whether relining could deliver the same structural outcome.

How CIPP Pipe Relining Works in NSW

Cured-in-place pipe relining installs a new structural tube inside the existing damaged drain pipe using a resin-saturated felt or fibreglass sleeve that is inverted or pulled through the host pipe, then inflated against the pipe wall and cured to form a rigid structural liner. The two main curing methods used in NSW are ambient or steam cure, where the resin cures at the surrounding ground temperature over several hours, and UV cure, where a UV light source is pulled through the sleeve after installation, curing the resin in a controlled and rapid process that takes minutes per metre rather than hours. UV cure relining is increasingly common in NSW for residential drain sizes because it provides consistent cure quality that is less sensitive to ground temperature variation, and the short cure time reduces the period during which the drain is out of service.

Before the liner is installed, the pipe must be thoroughly cleaned by hydro-jetting to remove all root material, sediment, grease, and scale from the pipe wall. Any remaining debris between the liner and the host pipe wall will create voids that compromise the liner's bond and structural performance. After cleaning and before the liner is prepared, a CCTV inspection confirms the pipe is clean and documents the starting condition. After curing, the liner is reinspected by CCTV to verify it has fully conformed to the pipe wall, that there are no voids or delamination, and that any branch junctions that were cut open during installation are correctly profiled. This post-installation CCTV record is as important as the pre-installation survey and should be provided to the owner as part of the completion documentation.

The finished liner reduces the internal diameter of the host pipe slightly, typically by 6mm to 12mm depending on the liner wall thickness required for the specific pipe diameter and structural design. For a standard 100mm residential sewer pipe, this means the internal bore reduces from approximately 100mm to 88mm to 94mm. This reduction is acceptable for residential sewer drainage purposes under AS/NZS 3500.2, which governs sanitary plumbing, because the design flow capacity of a correctly graded 88mm bore pipe at typical residential drain gradients is more than adequate for household fixture loads. For larger diameter pipes or for pipes operating close to their design flow capacity, the hydraulic impact of the bore reduction should be considered in the relining design.

Liner wall thickness is determined by a structural design calculation that considers the pipe diameter, the depth of cover above the pipe, the soil type and groundwater conditions, and the surface loads above the pipe including vehicle loading for pipes under driveways or roads. Reputable NSW relining contractors apply AS 11295:2019 Plastics Piping Systems for Renovation of Underground Non-Pressure Drainage and Sewerage Networks as the basis for structural design, and should be able to provide the design calculation for the liner thickness specified on request. A thicker liner is not automatically better if it reduces bore beyond what is needed for drainage capacity, and a liner specified at the minimum wall thickness for the design conditions is entirely appropriate if the calculation supports it.

Why CCTV Inspection Must Come Before Any Repair Decision

A CCTV drain inspection before committing to relining or excavation is not optional. It is the essential diagnostic step that determines which repair approach is appropriate and what the exact scope of the repair needs to be. Without a CCTV report, the repair contractor is working from a description of symptoms rather than a direct observation of the pipe condition, and the resulting scope may be undersized (missing damaged sections adjacent to the visible blockage), oversized (relining a pipe that only needed a localised patch at one joint), or simply wrong (recommending relining for a pipe that has collapsed and requires excavation). Our blocked drains guide covers the CCTV inspection process in detail and explains how to read a CCTV condition report to understand what each finding means for the repair decision.

The CCTV report should identify each defect by its position along the pipe run (typically measured in metres from the inspection access point), the defect type using a recognised classification system, the severity of each defect, and the overall structural grade of the pipe section. Defect types commonly identified in NSW sewer and drain CCTV surveys include root intrusion (classified by the percentage of pipe cross-section obstructed), open joints (joints where the pipe sections have separated or the mortar seal has failed), circumferential cracking, longitudinal cracking, joint displacement (where the pipe ends have moved out of alignment at a joint), deposition (sediment or grease accumulation), and pipe deflection (where the pipe cross-section has changed shape under ground loading). Each defect type has different implications for whether relining is appropriate, and a CCTV report that lists defects without explaining their significance for the repair decision is not a useful document on its own.

The structural condition grade of a pipe section, typically assessed on a scale from Grade 1 (sound condition, no structural defects) to Grade 5 (structurally failed or collapsed), drives the repair urgency and method selection. Grade 3 and Grade 4 pipes with open joints, root intrusion through multiple joints, and moderate cracking are ideal relining candidates because the pipe alignment is still intact and the liner can conform to the existing pipe geometry. Grade 5 pipes with complete joint separation, significant pipe deflection exceeding 10 to 15 percent of the original diameter, or partial collapse require excavation and replacement because a liner cannot conform to a severely deformed or collapsed host pipe and will not provide the structural outcome the property owner is paying for. Our stormwater drainage guide covers pre-purchase drain inspections and explains what to look for in a CCTV report before acquiring a property with older drainage infrastructure. Our gas leak repairs guide covers the separate but related process of inspecting and testing gas line infrastructure during the same pre-purchase assessment where drainage CCTV is being carried out.

Relining vs Excavation: Making the Right Choice in NSW

Relining is the better choice when the pipe alignment is intact, access to the pipe is difficult or disruptive, the property owner wants to avoid damage to existing paving, landscaping, or structures above the drain, and the total length to be repaired makes the per-metre relining cost competitive with excavation including reinstatement. For a typical inner Sydney residential property with a 10 to 15 metre sewer run under a tiled patio and established garden, relining at $200 to $350 per metre totalling $2,000 to $5,250 will almost always be significantly cheaper than excavating through the paving and garden, replacing the pipe, and reinstating the surface to the same standard. The reinstatement cost after excavation in these locations is often as large as the excavation and pipe replacement cost itself.

Excavation is the better choice when the pipe has collapsed, deflected beyond the point where a liner can conform to it, offset so severely at a joint that two separate pipe ends cannot be bridged by a continuous liner, or when there is a point failure such as a single broken pipe section in otherwise sound pipe where a targeted dig and patch is faster and cheaper than lining the full run. For properties in new residential areas with PVC sewer pipes in good alignment that have a single localized root intrusion point at one joint, a targeted excavation and joint repair is likely to cost $1,500 to $3,000 and resolve the problem permanently, while lining the full run for a single joint defect in an otherwise sound pipe may not represent the best use of the owner's money. The CCTV report identifies these situations clearly when the inspection is conducted properly.

Cost comparison between the two approaches should always include the full scope: for relining, this means CCTV before, hydro-jet cleaning, liner supply and installation, junction reinstatements, and CCTV after; for excavation it means the dig, shoring if required, pipe and fittings supply, new pit if needed, backfill and compaction, and full surface reinstatement including council permits for road reserve work where applicable. Omitting reinstatement from an excavation quote or omitting the CCTV components from a relining quote makes the comparison misleading and typically understates the true cost of whichever option is being presented more attractively. Our emergency plumber guide covers the immediate response for actively failing drain situations where the choice between relining and excavation may need to be made urgently.

Junction Relining in NSW Drain Systems

Junction relining is one of the most technically demanding and frequently discussed aspects of CIPP relining in NSW, and it is important because junctions are the most common point of root entry in residential sewer systems. A junction is the connection point where a branch drain from a fixture or secondary building connects into the main sewer drain run. In older clay and concrete pipe systems, junctions were formed by cutting a hole in the main pipe and inserting a saddle connection sealed with cement mortar, and the mortar seal around the saddle is almost always the first point of deterioration, providing an open pathway for root entry long before the main pipe joints show comparable deterioration.

When a CIPP liner is installed through the main pipe run, it covers the junction opening from the inside, creating a sealed main line. However, the branch drain still needs to connect to the main, and the junction opening in the liner must be reinstated by cutting through the cured liner precisely at the branch connection point. This reinstatement cut is performed by a robotic cutter controlled from the surface using the CCTV camera as a guide. If the cut is not made at all, the branch drain is completely blocked by the liner and fixtures on that branch cannot drain. If the cut is inaccurate or oversized, the liner edge around the branch opening is unsupported and can lift away from the host pipe, creating a void and a new root entry point at the junction.

A junction hat or lateral seal is the complementary repair for the branch connection itself. It is a short pre-formed CIPP section shaped to fit over the junction opening from inside the main pipe, sealing the transition between the branch and the liner with a structural resin bond. Junction hats are installed by the same robotic inversion equipment used for the reinstatement cut and are cured in place before the main liner installation proceeds in some systems, or after the main liner and junction cut in others depending on the contractor's methodology. Not all NSW relining contractors routinely include junction hats, and their inclusion significantly affects the long-term performance of the relining where root-prone junctions are present. Asking specifically whether junction hats are included and what their installation method is forms an important part of comparing relining quotes.

Liner Materials and Australian Standards

The quality of the liner material installed in a NSW drain relining project determines the long-term structural performance and the validity of the warranty offered, and it is not something that is visible once the job is complete. CIPP liners for sewer and drain applications in Australia are governed by AS 11295:2019, which sets minimum requirements for liner design, material properties, installation procedures, and quality assurance. The standard specifies the tensile strength, flexural strength, and chemical resistance that the cured liner must achieve, and reputable contractors can provide the product data sheet and the design calculation confirming the installed liner meets these requirements.

The felt sleeve carrying the resin is typically manufactured from either a polyester non-woven felt or a fibreglass reinforced felt, with fibreglass liners generally providing higher strength and stiffness for a given wall thickness and better long-term resistance to wet environment chemical exposure. The resin systems used in Australian CIPP relining are primarily polyester, vinyl ester, or epoxy based. Epoxy resins provide the highest chemical resistance and are preferred for sewer applications where the liner is in continuous contact with sewage, though they are more expensive than polyester. Vinyl ester resins provide intermediate performance between polyester and epoxy and are widely used in NSW residential and commercial relining projects. The specific resin system used should be disclosed in the relining contractor's product documentation and confirmed as appropriate for the application.

UV-cure systems from Brawoliner (German manufactured, widely used in NSW), SAERTEX-LINER (fibreglass reinforced UV sleeve), and ambient cure systems from companies including Interflow (which manufactures its own Brawoliner-licensed product in Australia) and Nuflow Technologies (Australian-developed ambient cure system with extensive NSW installation history) represent the main product families encountered in NSW residential and commercial relining projects. These brands have established installation track records and available product technical data, and their use by a licensed NSW contractor provides a reasonable baseline of quality assurance. Asking the contractor which liner system they are installing and confirming that product data sheets are available to review is a straightforward step that protects the owner's interests. Our commercial plumbing maintenance guide covers relining as part of a planned maintenance programme for commercial properties with older drainage infrastructure across multiple buildings or floors.

When Drain Excavation and Replacement is Required in NSW

There are specific pipe conditions where excavation and replacement is not just an option but the only correct repair approach, and understanding these conditions helps property owners evaluate contractor recommendations honestly. A pipe that has collapsed, meaning the pipe wall has fractured and the pipe cross-section is no longer identifiable as a continuous tube, cannot be relined because the liner has no intact host pipe to conform to. A CCTV camera that cannot physically travel through a section of pipe due to a collapse or severe deformation is a clear indicator that excavation will be required, regardless of what proportion of the pipe run is otherwise intact.

Joint offset, where two adjacent pipe sections have moved laterally so that their ends no longer align and there is a step or ledge inside the pipe at the joint, presents a specific challenge for relining. Minor offsets of less than 20 to 30 percent of the pipe diameter can be bridged by a correctly designed liner using the liner's flexibility during installation to conform to the offset geometry. Larger offsets, particularly those exceeding 30 percent of the pipe diameter, prevent the liner from making continuous wall contact across the joint, leaving a void that compromises the structural outcome and creates a point of future failure. A CCTV survey that identifies large joint offsets as the primary defect is indicating that excavation and realignment is the appropriate remedy rather than relining.

Pipe access for excavation in NSW requires consideration of the regulatory requirements that apply before and during the dig. Excavations deeper than 1.5 metres require a safe excavation method statement addressing trench shoring or battering under the Work Health and Safety Regulation 2017, and SafeWork NSW inspectors can and do inspect excavation worksites. Excavation in the road reserve requires a council permit, typically a road opening permit, with the plumber responsible for traffic management and reinstating the road surface to the council's specification. For excavations near utility services, a Dial Before You Dig enquiry is mandatory under the Work Health and Safety Act 2011 to locate underground electrical, gas, telecommunications, and water assets before digging commences. The SafeWork NSW website provides the current excavation safety requirements applicable to all drainage excavation work in the state.

The reinstatement scope after drain excavation in NSW is an element that separates detailed quotes from superficial ones. Reinstating a driveway excavation in Sydney involves not just backfilling and compacting the trench but matching the existing surface material, whether it is exposed aggregate concrete, coloured pavement, block paving, asphalt, or tiled finish. These reinstatements are specialist works that require their own materials and trades, and a drain replacement quote that provides a lump sum for "reinstatement" without specifying the material and extent is carrying significant price risk. Asking each contractor to specify the reinstatement scope and material in the quote protects the owner from unexpected additional costs when the excavation is complete. Our burst pipe repairs guide covers emergency excavation situations where the urgency of the repair affects the reinstatement options and timing. For leaking tap and fixture connections that contribute to sustained ground moisture and accelerate pipe joint deterioration, our leaking tap repairs guide covers prompt repair as a low-cost preventive measure.

Warranties for Pipe Relining in NSW

Warranty terms for CIPP pipe relining in NSW vary considerably between contractors, and understanding what a warranty actually covers is as important as the warranty period stated. Most reputable NSW relining contractors offer a structural warranty of 10 to 25 years on the installed liner, covering delamination, failure of the liner wall, and water infiltration through the liner material itself. The warranty typically does not cover mechanical damage to the liner caused by subsequent construction activity near the pipe, root intrusion through incorrectly reinstated junctions, damage caused by flushing prohibited materials down the drain, or failure of pipe sections outside the lined run.

The warranty is only as valuable as the contractor's ability and willingness to honour it, which means the financial stability and operating continuity of the relining business matters alongside the document's terms. A 25-year warranty from a contractor who is no longer trading in five years is an unenforceable document. Asking about the contractor's tenure in the NSW market, whether they carry professional indemnity insurance for the warranty work, and whether the warranty is backed by the liner manufacturer's own product guarantee alongside the contractor's workmanship warranty provides a more complete picture of the real protection offered. The NSW Fair Trading Home Building Act statutory warranty framework also applies to drain relining work as building work, providing additional consumer protections alongside any contractor warranty.

Post-relining CCTV inspection, provided by the contractor as part of the completion documentation, is the objective verification that the liner has been installed correctly and that the warranty covers the installed condition rather than a theoretical specification. Request the post-installation CCTV video and confirm that it shows continuous liner contact with the host pipe wall, correctly reinstated junctions, and no visible voids or delamination before signing off on the job completion. If the contractor does not routinely provide post-installation CCTV, treat this as a significant quality concern. Our strata and body corporate plumbing guide covers the warranty and certification requirements for relining work on common property drainage in NSW strata schemes, where the owners corporation holds the warranty obligation on behalf of all lot owners.

Common Mistakes NSW Property Owners Make with Drain Repairs

The most costly mistake is accepting a relining or excavation recommendation without first obtaining and reviewing the CCTV report. A contractor who recommends relining based on a blockage history and a symptom description rather than direct pipe observation may be proposing a solution that is either unnecessary or insufficient for the actual condition of the pipe. The CCTV report is the only objective basis for the repair decision, and an owner who does not ask for it is accepting the contractor's word rather than the evidence.

Relining a pipe without reinstating junctions correctly is a serious installation error that produces a new blockage at every branch connection within days of completion. This mistake typically occurs when the robotic cutter used for junction reinstatement is not calibrated correctly for the liner thickness, producing an undersized cut that partially or fully blocks the branch drain. Always confirm that junction reinstatement is specifically included in the scope and ask how junction locations are identified and marked before the liner is installed.

Accepting the lowest relining quote without asking which liner system is being installed is a risk that is difficult to evaluate after the job is done. A thin polyester liner installed with minimal resin saturation will look identical to a correctly designed liner immediately after installation, but will fail structurally within years rather than decades. Asking for the liner product data sheet and the structural design calculation before accepting a quote is the only reliable way to compare material quality between competing proposals rather than comparing prices for an unspecified product.

Failing to obtain a post-installation CCTV record means the owner has no independent evidence of the installed liner condition at completion, which substantially weakens any future warranty claim if the liner develops problems. It also means the contractor has no baseline record against which subsequent inspection findings can be compared. Both parties benefit from post-installation CCTV documentation, and any contractor who declines to provide it should be questioned about their reasoning.

How to Read Your CCTV Drain Report in NSW

A CCTV drain report uses a grading scale from 1 to 5 to describe structural condition. Grade 1 means the pipe is sound with no defects. Grade 2 shows minor defects such as light sediment or surface cracking that do not affect structural integrity. Grade 3 identifies moderate defects including open joints, root intrusion occupying less than 25 percent of the pipe bore, and minor cracking , this is the typical finding on a 40 to 60 year old clay sewer pipe that is still serviceable but approaching the point where intervention is warranted. Grade 4 shows significant structural deterioration with root intrusion occupying 25 to 50 percent of the bore, joint displacement, or longitudinal cracking affecting the pipe wall integrity , this is the clear relining candidate. Grade 5 means the pipe has collapsed, deflected severely, or has a joint offset so large the pipe sections are no longer connected , this requires excavation.

Defect positions in the report are given in metres from the camera entry point. If the report says "root intrusion at 4.2m, 7.8m, and 11.3m," those are the three joint locations where roots have entered. If all other measurements between those points show Grade 1 or 2, the contractor proposing to reline the full 15m run should be asked whether targeted joint repair at those three points is sufficient, or whether the full run relining is structurally justified. A contractor who can explain this clearly with reference to the CCTV footage is one who understands the work.

Joint offset is reported as a percentage of pipe diameter. A 10 percent offset on a 100mm pipe is a 10mm step at the joint , manageable for relining. A 35 percent offset is a 35mm step , the pipe ends have moved significantly and relining is unlikely to conform correctly across that joint. If you see joint offset reported above 30 percent at any location, ask the contractor specifically how they intend to address it rather than assuming the liner will bridge it.

Pipe Relining and Drain Repair Costs Across Sydney

Sydney relining pricing reflects strong competition in the residential market, particularly for 100mm sewer relining in established inner and middle ring suburbs where the volume of work is highest. Access conditions and the prevalence of sandstone in inner Sydney suburbs add to excavation costs, reinforcing the value of relining where the pipe alignment allows it. Western Sydney's newer housing stock with PVC sewer drainage has a lower rate of relining demand overall, but older homes in growth corridor suburbs with original terracotta or concrete drainage are increasingly generating relining work as the infrastructure ages.

The inner west of Sydney, covering suburbs such as Marrickville, Leichhardt, Newtown, Ashfield, Strathfield, and Burwood, generates some of the highest volume of residential pipe relining work in NSW. Properties in these areas were predominantly built between 1880 and 1960 with vitrified clay sewer drains, and the combination of large established street and garden trees, deteriorated cement mortar joints, and clay soil movement has produced a generation of pipes that are well past the point where blockage management alone is viable. For many of these properties, a single reline of the main sewer run from the house to the property boundary, typically 10 to 20 metres at 100mm diameter, resolves a multi-year history of recurring blockages for a cost between $2,000 and $7,000 including CCTV before and after. Our blocked drains guide covers the root intrusion management programme that precedes a relining decision and how to use recurring blockage frequency as a trigger for CCTV assessment.

Pipe Relining and Drain Repair Costs in Regional NSW

Regional NSW relining pricing is typically 5 to 15 percent below Sydney metropolitan rates, though in some regional centres with a limited number of CIPP relining contractors the per-metre rates can approach Sydney pricing due to lower competition. The availability of contractors with UV-cure relining equipment is concentrated in Sydney, Newcastle, and Wollongong, with most regional NSW relining work performed using ambient-cure systems, which are equally effective when installed correctly but require longer cure times that may mean the drain is out of service overnight. For very remote regional locations, mobilisation charges for a specialist relining crew may add $500 to $2,000 to the project cost.

Older regional town centres across NSW including Goulburn, Lithgow, Cessnock, Maitland, Grafton, and Kempsey share many of the drainage characteristics of inner Sydney: clay and concrete pipes from the early to mid twentieth century, established tree canopies over the drainage alignments, and a mix of original terracotta pipe in variable condition depending on the specific block. Regional property owners in these areas who have experienced recurring drain blockages over several years without a long-term resolution are in many cases candidates for relining as the same cost-effective structural repair that their inner-city counterparts have increasingly adopted. Our rainwater tank plumbing guide and new home plumbing guide cover related drainage work that is frequently coordinated with relining projects during broader property maintenance or renovation programmes.

What to Look For in Pipe Relining Quotes in NSW

A quality pipe relining quote in NSW specifies the exact liner product by brand and model, the liner wall thickness and the structural design basis for that thickness, the resin system, the curing method (UV or ambient), the pipe length and diameter to be lined, the number of junctions to be reinstated and the reinstatement method, whether junction hats are included, and what CCTV services are included both before and after installation. A quote that simply says "reline 12m of 100mm pipe" without these details is asking the owner to accept a significant level of specification ambiguity for a substantial capital expenditure.

Ask each contractor whether they carry public liability insurance of at least $5 million and whether they hold a current drainage plumbing licence endorsement. Ask specifically what happens if the liner fails to cure correctly or delaminates from the host pipe, and confirm whether that scenario is covered by the contractor's workmanship warranty or treated as a separate rectification charge. Ask how the CCTV post-installation record is provided and what format the video and written report take. These are not unreasonable questions from a customer who is being asked to spend $3,000 to $15,000 on a repair to infrastructure they cannot see after the job is done.

Getting three itemised quotes for the same specified scope is the most reliable way to compare relining pricing in NSW, but only if all three quotes specify the same liner product and installation method. A comparison between a UV-cure fibreglass liner quote and an ambient-cure polyester liner quote is comparing different products at different quality levels, not the same service at different prices. Specify in your request for quotes that you want the liner brand, model, and wall thickness included, that post-installation CCTV must be included, and that junction hat installations must be separately itemised. The NSW Civil and Administrative Tribunal is the resolution pathway for disputes between property owners and drain relining contractors where the work has been completed but the owner believes the outcome was not as contracted.

After Relining: Maintenance and Monitoring

A correctly installed CIPP liner in a residential sewer run requires minimal maintenance over its warranted life. The smooth bore surface of the cured liner is significantly more resistant to root entry and grease accumulation than the original clay or concrete pipe it replaced, and blockages in a relined pipe section are uncommon in the years following a well-executed installation. The maintenance focus after relining shifts to the remainder of the drainage system outside the lined section, particularly any pipe branches or secondary runs that share the drainage network but were not included in the relining scope.

A CCTV inspection of the relined section every five to seven years, or sooner if drainage symptoms reappear, provides the ongoing condition monitoring needed to identify any early delamination, movement at the ends of the liner, or damage to reinstated junctions before these defects develop into a drainage failure. For properties where the relining was installed as part of a larger drainage programme covering multiple pipe runs and junctions, maintaining a record of the original post-installation CCTV report makes subsequent inspections more meaningful because the inspector can compare current conditions directly against the documented starting point. Our stormwater drainage guide covers maintenance of the stormwater drainage infrastructure that runs alongside the sewer system on most NSW properties, because both systems benefit from a coordinated maintenance programme rather than being managed in isolation.

For commercial properties with multiple drainage runs including both sewer and stormwater, a structured relining and maintenance programme planned across the full drainage asset register is significantly more cost-effective than responding to individual drain failures as they occur. Mobilisation costs for CCTV inspection and relining crews are the same whether one run or five runs are included in a single programme, and the per-metre cost of relining typically reduces when multiple runs are included in a single mobilisation. Our commercial plumbing maintenance guide covers the planned maintenance programme approach for commercial drainage infrastructure in NSW. For properties that include laundry facilities or kitchen waste lines alongside sewer drainage in the relining scope, our laundry plumbing guide and kitchen plumbing guide cover the fixture plumbing context for these drain branches.
