Slab Leak Testing, Location & Repair

Our process of both detecting and ruling out other leak possibilities involves isolating different areas of the water supply, narrowing down the scope, and performing a multiple-system pressure test. This starts with some visual observations:

-Water meter
-Toilets & toilet tanks
-Interior faucets
-Water heater(s)
-Hose spigots
-Shut-off valves

Next, we’ll isolate the irrigation system from the main water line. We’ll check for movement on the meter, and if we see it, we’ll move on to isolating the plumbing in and underneath the house from the main yard line. We’ll also usually perform a static pressure test of the whole system, filling the home with water using a pressure gauge at the hose spigot for about 15-20 minutes.

Once we completely isolate the house, any drop-off in pressure indicates a leak. We may perform the test multiple times to determine whether the leak is on a cold or hot water line. Then, we can move on to locating the leak.
