Can I test for leaks myself before calling a plumber?
Yes, there are several things you can do. For example, check your water meter when no water is being used. If the meter is still moving, you likely have a leak. You can also inspect around fixtures, toilets, hoses, and look for signs of moisture. Seattle Public Utilities has a guide on how to test for leaks; for more detailed steps, you can read our blog that walks through the process. How Locate A Leak DIY

What kinds of leaks can Best Plumbing detect?
We detect all kinds, including pinhole leaks, slab leaks, toilet leaks, appliance leaks, water line leaks, sewer line leaks, and more. Both residential and commercial.
Do all leaks require immediate repair?
Not always. It depends on “how bad” the leak is, where it is located, and what risk it poses. Small, slow leaks may just be monitored if they are not doing damage. But any leak that’s causing structural damage, mold, health risks, or wasting a lot of water should be dealt with ASAP.
How do I know if I have a leak in my plumbing system?
Some common signs are unexplained high water bills, damp spots or stains on walls/floors, mold or mildew growth, water pooling where it shouldn’t, or the sound of running water when everything is off. Best Plumbing uses a variety of detection methods including acoustic, thermal imaging, moisture sensors, tracer gas, pressure, dye, and meter testing to pinpoint leaks.
How invasive is modern leak detection? Will it damage walls, floors, landscaping?
At Best Plumbing we use non-destructive techniques first: acoustic detection, thermal imaging, moisture sensors, etc. These let us locate leaks without tearing up walls, floors, or digging up a yard—unless absolutely necessary for repair.
