Drain Locating & Depth Marking in Sydney
Drain locating and depth marking in Sydney: the excavator is booked for Tuesday, the pool shell is on order, and nobody actually knows where the sewer crosses the backyard or how far down it sits.
Tell us what's happening

The short answer
Drain locating traces where your sewer or stormwater line runs and how deep it sits, so you can dig, build or install a pool without hitting it.
How it works
Step 1: Call or book online
Tell us what is happening. We ask the right questions and book a time that suits you.
Step 2: We find the cause
A licensed plumber diagnoses it properly, with a drain camera, leak detection or a pressure test where it helps.
Step 3: A fixed price, agreed first
You agree the price before any work starts. We quote the job, not the hour, so there are no surprise charges.
Step 4: Done right, guaranteed
We finish the job, clean up, and back our workmanship with a lifetime labour guarantee.
Step 5: You know the price first
The figure for the whole job, in writing, before anyone starts. That figure is what turns up on the invoice.

Questions and answers
Start with the sewer service diagram from Sydney Water, then have a licensed plumber put a transmitter down the pipe and track it from above. That gives you the real route rather than the drawn one.
If any footing, pier or pool shell is going within a couple of metres of where the sewer might run, yes, and it is far less trouble than one strike. If you are building well clear of the line and the certifier hasn't asked, you can probably skip it.
Very close for route, and depth readings are good in normal ground. Heavy fill, rock or nearby metal can affect readings, and we tell you on site if any mark is less certain.
Yes. Stormwater pits and the lines between them take the same camera and transmitter, which is handy when a downpipe disappears into the ground and nobody knows where it goes.
Usually, through a gully, a fixture or the boundary shaft. If there is truly no access, we tell you what it would take to make one.
It depends on how many lines you need traced and how easy they are to get into. The price is in writing before we start.
