Coquitlam is committed to providing safe and reliable water service to residents and businesses. Common issues are listed on this page along with potential solutions. If you conduct any of these inspections and you cannot determine the cause or solution, then contact the city for assistance.
Occasionally, the tap water in your home may look cloudy. There could be a number of causes including:
If you find dirty water in your home, run the cold water tap in your tub or your outside tap until the water runs clear. This should clear up within 30 minutes.
Most water pressure problems are not due to the City’s water system but instead are due to problems in the building’s plumbing system.
Check that the valve for this tap is wide open. You will usually find this valve under the sink or behind the toilet. Make sure the screens on the tap are clean.
Have your leaking hot water tank inspected by a plumber before replacing it. The leak could simply be a result of a faulty pressure reducing valve. This valve is the cone-shaped device located on your water supply line next to the main shut-off valve.
If you choose to inspect your water tank and replace a valve yourself:
The City is responsible for leaks from the water pipes on city property. This could be from the water main or from the service to the property up to the valve at property line. If you notice water leaking on City property, contact Engineering and Public Works Customer Service.
City staff will confirm if there is a leak and also determine if it is on the City’s side of the service valve or on private property. Once a leak is confirmed on City property, repairs will be scheduled based on the severity of the leak and availability of staff.
You may have a water leak if you notice one of these situations:
Property owners are responsible for all the water pipes starting at the service valve near the property line. If a leak is noticed near the property line, you may be able to check if the leak is on the private side by locating and shutting off the water service valve. After the valve is shut off, if the flow or sound of water is reduced or stopped completely, the leak is most likely on your property.

Snow can bury valve boxes, service boxes and fire hydrants which can make it hard to access during emergencies. To prevent these conditions there are several things you can do:

To get information on the valve location (if available), visit the Engineering and Public Works Department at City Hall.
