Leak Detection

A higher-than-expected water bill is often the first sign of a leak. Even small, hidden leaks can waste large amounts of water over time and increase your bill.

Most water leaks happen quietly and out of sight. Toilets, underground pipes, and appliances can leak for weeks or months before they’re noticed.

Even a small leak can add up:

• A running toilet can waste hundreds of litres per day

• A slow underground leak can significantly increase your bill without obvious signs indoors

• Outdoor leaks are often missed until water use spikes

Because water is billed based on usage, leaks on your property can result in higher charges.

How to Check for Leaks

Your water meter is one of the easiest ways to check for hidden leaks.

Step-by-step:

1. Make sure no water is being used inside or outside your home (turn off taps, appliances, irrigation, etc.).

2. Locate your water meter (usually near the road in a meter box).

3. Look for the leak indicator (often a small triangle or star-shaped dial).

4. If the indicator is moving, water is flowing. This may indicate a leak.

5. For confirmation:

   • Record the meter reading

   • Wait 30–60 minutes with no water use

   • Check the reading again. If it has changed, a leak may be present.

Check for Toilet Leaks

Toilets are the most common source of household leaks — and they’re easy to test.

Toilet dye test:

1. Add a few drops of food colouring to the toilet tank.

2. Do not flush.

3. Wait 15–20 minutes.

4. If coloured water appears in the bowl, the toilet is leaking.

A worn or misaligned flapper is usually the cause and is often an inexpensive fix.

Other Common Places Leaks Occur

Check these areas regularly:

• Dripping faucets or showerheads

• Washing machine or dishwasher connections

• Water softeners or filtration systems

• Water heaters

• Outdoor taps and hoses

• Irrigation or sprinkler systems

• Underground service lines (often shown by soggy ground or unusually green patches of grass)

What to do if you find a leak

• Minor leaks (toilet flappers, faucet washers) may be suitable for DIY repair.

• Larger or hidden leaks should be assessed by a licensed plumber.

• Underground or service-line leaks can be difficult to detect and may require professional equipment.

The Township is responsible for the water system up to the property line. Leaks on private property are the responsibility of the homeowner.
