How to Check Your Meter for Leaks

Finding water leaks saves water, which saves money on your water bill. Routinely checking for leaks and monitoring your water bills closely can help reduce the likelihood that leaks will go unnoticed. If you suspect you may have a leak, call one of our customer service representatives at 425-787-0220 during business hours (8:00 a.m. to 5:00 p.m.) or follow these easy steps to determine if you have a leak in your service line.



Most water meters are in the Right-of-Way at the edge of the road near the property line. The meter will be in a ground level cement box with a lid. Remove the lid. (It is not unusual for the meter box to be filled with water or dirt.) Flip up the plastic cap in the box to expose the register. If there is more than one meter box, find the meter number on the cap that matches the meter number that appears on your water bill. If you do not have a copy of your bill or cannot locate your meter, call an AWWD customer service representative at 425-787-0220 (Monday through Friday, 8:00 a.m. to 5:00 p.m.) to obtain your meter number.




Make sure all water is shut off in the residence. Look at your meter to see if the low flow (leak) indicator is turning.  A leak indicator will be a black or red triangle or a blue wheel (similar to what is pictured). If it is turning, you either have a leak or something in the residence is using water (e.g., toilet running, drippy faucet, etc.)




If you know where the shut-off valve is in your home, you may turn that off to determine whether the leak is in your service line or after it enters the residence. After closing the shut-off valve, check your meter again. If the leak indicator is still turning, the leak is in your service line. Please be advised that all leaks after the water meter are the homeowner’s responsibility to repair.
