A real person answers, day or night
A drainage plan copied from a flat block won't survive a slope
Every property here sits on its own fall and its own soil, and a system that ignores that fails eventually. Call (02) 9072 0520, tell us about the project, and we'll design around your block, not a template.
Designing drainage for this block, not a textbook one
- The fall varies a lot by street Between the ridge streets and the foreshore, grades change enough that a drainage design copied from a flat-block plan simply won't perform the way it should here.
- Rock changes the dig, not the design Stone sits within easy reach of the surface on parts of this suburb's blocks, and that changes how a new line gets installed, not whether it can be, so we route around it rather than blast straight through.
- New work still meets old infrastructure Every new or rebuilt drainage run eventually ties into the street's existing mains at the boundary, and that connection point gets checked before a single trench is dug, not after.
Drainage repair and installation services we provide
New drainage, rebuilt drainage and everything the yard needs to actually work with the block it sits on, each one designed and certified rather than fitted from a standard template:
New drainage design
We design new drainage runs around the block's real fall and soil, from stormwater lines to sewer connections, so a renovation or a knockdown rebuild starts with a system built for this ground rather than a generic set of plans.
Full pipe replacement
Where a section is too far gone for relining we excavate and replace it entirely with modern PVC, restoring proper fall and joint integrity along the whole run, then certify the finished work before the open trench gets backfilled again.
Extension and renovation drainage
Extending a kitchen, adding a bathroom or building a granny flat near Letitia Street usually means new drainage has to tie cleanly into decades-old infrastructure, and we plan that connection before the builders lock in a floor plan around it.
Commercial fitout drainage
Cafes and shops fitting out near the Oatley West strip get drainage designed for real kitchen loads, including properly sized grease management, so the system copes with genuine service volume instead of failing during the very first busy trading weekend.
What a knockdown rebuild actually inherits
- The block is new, the connection point isn't A rebuild's internal drainage might be brand new PVC throughout, but it still joins the same ageing main at the boundary that served the house before it, which the design has to account for.
- Older sections nearby can complicate approvals Working near shared or ageing infrastructure sometimes means extra checks before a connection is signed off, and we handle that process rather than leaving it as a surprise on handover day.
- A fresh survey beats an old plan Site plans from a previous build rarely match what's actually in the ground, so we camera and confirm the real layout before any new drainage gets designed around an assumption.
Common drainage design problems we fix
Undersized for the reno
A bathroom or laundry added without upgrading the drainage feeding it often works fine until everything runs at once, and resizing the line properly the first time costs far less than revisiting it after the tiling is finished.
Wrong fall, slow drainage
A pipe laid without enough fall drains sluggishly no matter how new it is, and the fix isn't a bigger pipe but a properly graded one, which is exactly the kind of defect a rushed installation leaves behind for good.
Why the design stage matters more than the pipe
A drainage system is only as good as the plan behind it, and a mistake made at design stage gets buried under concrete or garden beds for years before anyone notices it was ever wrong:
- A bad connection fails quietly An undersized or poorly graded line can work adequately for years before a heavy load finally exposes it, by which point the fix means undoing finished work.
- Certification protects the sale Drainage installed and certified properly avoids the compliance headaches that surface at building inspection stage, whether that's this year or when the property eventually sells.
- Good design costs less over the system's life A pipe sized and fallen correctly the first time avoids the repeat callouts that an undersized shortcut quietly guarantees down the track.
How it works
How drainage repair and installation works, step by step
- 01
Call and tell us
Ring (02) 9072 0520 and describe what's happening, and a licensed plumber, not an answering machine, will tell you what it likely means, what to stop using, and when we can realistically be there.
- 02
Quote before work
Your plumber inspects the job properly, runs whatever diagnosis it genuinely needs, and hands you a single fixed written price covering the complete fix, with a $0 call out fee and nothing added afterwards.
- 03
Survey, install, test
We survey the block's actual fall and soil, design the run to suit it, then install and pressure-test every single joint before backfilling, so what goes in the ground matches exactly what was certified on paper.
- 04
Backed for life
Everything we complete is covered by our Lifetime Labour Warranty, the promise that outlasts the job itself: if it's not right, we come back. No questions. No cost.
Why choose Your Plumber Oatley
Fixed prices, kept
Every job is priced upfront in plain writing before any work starts, the invoice always matches that number, and weekend or late-evening timing changes nothing, because overtime rates simply don't exist here.
Licensed and insured
Your Plumber Oatley works under licence #275278C with full insurance behind every job, and the compliance certificates that protect your home's paperwork trail arrive with the invoice, without you ever needing to ask for them.
Lifetime Labour Warranty
Workmanship here is guaranteed for life under our Lifetime Labour Warranty rather than for a warranty card's fine-print window, which says more about how the work is done in the first place than any advertisement could.
Genuinely local response
We work these streets constantly rather than commuting in from across Sydney, so the van reaching you has usually just left a job nearby, stocked for the faults the local houses actually develop.
Where we work
Areas we service
We design and install drainage on the same terms across Mortdale, Hurstville Grove, Connells Point, Peakhurst Heights and Penshurst as we do on Oatley's own blocks, matching every system to the ground it's actually going into.
Good questions, straight answers
Drainage repair and installation questions from Oatley
How much does new drainage installation cost?
Cost depends on the length of the run, the ground conditions and how it ties into existing infrastructure, but the site assessment, the design work and the written quote never cost you anything upfront.
How long does a drainage installation project take?
Simple extensions to existing drainage are often finished in a day, while a full new system for a knockdown rebuild takes longer, and you'll get a realistic timeframe as part of the written quote.
Do you handle council or building approvals for new drainage?
Where approvals are genuinely needed we manage that process as part of the job, and we'll tell you upfront if your project touches infrastructure that isn't ours to alter without sign-off first.
How is a drainage repair different from a full installation?
Repair fixes or replaces a specific damaged section of an existing system, while installation designs and builds drainage from scratch for a renovation, extension or new build, each priced and planned differently.
Does the sloping ground around here affect how new drainage is designed?
Significantly: a system designed for a flat block underperforms on a falling one, so every job here starts from a survey of the actual grade rather than an assumption borrowed from somewhere else.
What happens if new drainage work fails down the track?
Every drainage installation and repair carries our lifetime workmanship guarantee, so a fault traced back to our own work is put right free of charge, no matter how many years have passed since installation.
