Detecting Water Leaks

Make sure you are not overpaying for water due to an undetected leak in your system! You could be paying for water you're not even using. Leaks often occur when component parts are worn and need replacing or adjusting.

If you fix an underground leak, you can apply for a leak adjustment on your water bill. Fill out the Leak Adjustment Request Form and email it to Property and Payment Services at to apply for your credit. You can also mail in the form or drop it off in person at City Hall.

Note: The City of Surrey is not responsible for detecting or fixing water leaks on private property.

How to Read Your Water Meter

Leaking Toilets

High volume water leaks often come from toilets. They are hard to detect and are usually caused by worn or misaligned parts.

A toilet that continues to run after flushing could be wasting 20 to 40 litres per hour - that's 175,000 to 350,000 litres (175 to 350 cubic metres) per year! That's enough water to fill a swimming pool. Leaks can cost  up to several hundreds of dollars per month!

To check for a leaking toilet, first listen for leaks. If you hear the sound of running water, your toilet is leaking. Still not sure? Take the dye test. Carefully remove the toilet tank lid. Place a dye tablet or some food colouring in the tank. After 15 minutes, check the water in your toilet bowl. If the water is coloured, you've got a leak. Toilet repairs may require the assistance of a plumber.

Leaking Pipes

A leaking service line or pipe in your home can add up to a significant amount of water waste. A small hole in a pipe (1.5mm) wastes a lot of water over 2 months. Continual leakage from a hole this size could cost you from several hundred dollars to thousands of dollars, depending on the diameter of the pipe. Locate and repair water leaks immediately to avoid paying for water leaking from your pipes.

Check all faucets and pipes periodically. Watch for drips, and quickly replace faulty parts. A leaking faucet can waste as much drinking water in a single day as the amount required to sustain one person for an entire week.

Leaking Irrigation Systems

Whether you use an in-ground sprinkler system or a single oscillating head, check it carefully for leaks.

The average garden hose delivers 27 litres of water a minute, so a split in the hose or a poor coupling could be wasting large amounts of water. Make sure the outdoor faucet is turned off after each use - even small drips add up to big waste. A leak in your in-ground sprinkler system is less noticeable than one in a hose.

If you think your in-ground sprinkler system may have a leak, check for wet patches in your lawn that do not dry. Contact your irrigation system contractor for a system check-up. Unfortunately, shutting off your sprinkler system will not correct the problem – you must repair the leak.

Electronic Water Leak Sensor


Electronic Water Leak Sensor

Get alerted as soon as water collects underneath your household appliances with an electronic water leak sensor. Purchase and place these sensors under major household appliances, such as dishwashers and washing machines. This will also protect your home against costly water damage and dangerous toxic mold by catching water leaks early. Visit your local home hardware store for more information.
