Pool and Spa Leak Detection in Spokane Valley
Summer heat and wind can evaporate a lot of pool water, so it can be hard to tell normal loss from a leak. A bucket test compares evaporation to actual water loss. We then pressure test plumbing lines and use dye testing around lights, skimmers and fittings. Finding the leak safeguards the pool shell and the soil around it.

Running toilets, worn faucet cartridges and leaking water heater connections waste more water than most people realize. A silent toilet leak can lose hundreds of gallons a day. We check flappers, fill valves, supply lines, softeners and water heater fittings. These repairs are usually quick and inexpensive.

Slab leaks are a common concern for homes with concrete foundations, especially where soils shift. Our technicians use specialized acoustic equipment and thermal cameras to pinpoint leaks under your home's foundation without destructive digging.

Many homeowners policies cover the cost of finding and accessing a sudden leak, though coverage varies. We provide a written report with photos to support your claim. Check with your insurer about your specific policy.
A slab leak is a leak in the water pipes embedded within or beneath your home's concrete slab foundation. Crawlspaces and basements are both common in Washington homes, and a damp crawlspace is often the first sign of a drainage or plumbing problem. Soil that shifts and settles strains plumbing lines, and temperature swings cause pipes to expand and contract over the years.
