General plumbing information

When can you do your own plumbing work?

You can only do minor plumbing work, such as changing tap washers, yourself. 

You need to hire a plumber to:

  • fix bigger problems
  • do renovation work
  • replace hot water systems, toilets and showers. 


Ask your plumber about the best products to help you save water at home.

You're responsible for maintaining the pipes and fittings on your property up to where they connect to our water, wastewater and stormwater networks.

This is your point of connection.

The pipes and fittings include all:

  • private water, wastewater and stormwater pipes and taps
  • pumps, tanks and other equipment used on your private pipes
  • pipes that you share with other properties
  • private pipes that service your property, even if they're not on your property.

You must also protect the water meter from damage and make sure we have access to read, maintain or replace it.
 
If you damage the meter, we may charge you to replace it.

If you have a leak in your water pipe, you must ask a licensed plumber to repair it.


To find out more about what you need to maintain, read our Responsibilities of connected customers policy.

We're responsible for our pipes and the water meter on your property.

Call us if you spot a leak in our pipes
If you see a leak in our pipes, call us any time on 13 20 90.

We may repair the water pipe that connects your property to our water network if the problem is less than one metre inside your property.

We don't offer a free repair service for:

  • wastewater pipes
  • unauthorised connections
  • pipes we can't get to easily
  • pipes that have been damaged by others
  • water pipes that run along the footpath or cross other properties to connect to our water network.

If you see a leak in our pipes, please tell us and we'll repair it.

Leaks occur when a pipe has been damaged in some way. This causes water or wastewater to leak out of the pipe.

You might have a leak in your water pipe if you have:

  • wet patches on your lawn during dry weather
  • patches of lawn or garden that are growing better than the area around it
  • a funny hissing sound coming from your water pipe
  • a water bill with much higher water use than usual, although you haven't changed the way you use water on your property.

Read about leak detection to learn how to find and prevent leaks.

Who do you call to report a leak?
Call a licensed plumber if you find a leak in your private water pipes.

If you think the leak is in one of our pipes, call us on 13 20 90.


If your bill was higher than expected, you may have a hidden leak. If a licensed plumber finds and repairs a hidden leak, you can apply for an allowance on your bill.

Blockages occur when there's something inside your pipe that stops it working properly.

Most blockages occur in wastewater pipes. They're usually caused by tree roots that have found a way into the pipes or when someone has put something down the toilet that it's not designed for. For example, children sometimes put soft toys down the toilet.

You might have a blockage in your pipes if:

  • your sinks, bath or toilet are slow to empty
  • your toilet is not flushing properly or has overflowed
  • your toilet or floor drain is making funny gurgling noises
  • sewage has overflowed from the drain near your outside tap.


Call a licensed plumber if you have a blockage in your private sewer pipes. If you think the blockage is in our pipes, call us on 13 20 90.

If you're out of pocket because of a blockage in our wastewater pipes, you may be able to make a sewer choke claim.
 

How to help stop blockages

You can help stop blockages by:

  • choosing the right trees
  • making sure you don't plant trees near any pipes. 
Your local nursery can give you advice on trees and their root system.

If you'd like to know where your pipes are, apply for a sewerage service diagram through Sydney Water Tap inTM.
If you know how, you can change washers or showerheads on your own property yourself.

You must hire a licensed plumber for all other work.

Don't forget to ask the plumber to give you a  Certificate of Compliance after they've finished the work.
