Water Main Leak Detection Seattle

Your water main is the primary line that brings pressurized water from the city supply into your home or building. When this line develops a crack or joint failure — which happens more often in older Seattle-area homes with aging infrastructure — the results can include dramatically higher water bills, reduced pressure throughout your property, and eventually serious soil erosion or foundation issues.
Leak Detection Northwest provides precise, non-invasive water main leak detection to help homeowners and property managers locate problems before they become emergencies.

How Do I Know If My Water Main Is Leaking?

Water main leaks are often subtle at first. Here’s what to look for:

Your water bill has increased without explanation
Water pressure throughout the home has dropped noticeably
You notice wet spots or pooling water near the street or at the front of your property
The area around your water meter box is unusually damp or muddy
You can hear water running inside your walls or underground when nothing is turned on
Your water meter is spinning even with all water use inside the home shut off

The last point is one of the easiest ways to check: locate your water meter, make sure all water in the home is off, and watch the dial. If it moves, water is escaping somewhere in the system.
