Accu-Find Slab Leak, Inc.

Water lines are pressure tested by connecting a pressure gauge to a faucet. The water is then turned off at the meter or the house cut-off, and the pressure is monitored to determine if there is a loss of pressure indicating a leak. If there is not an operable cut-off (usually close to the house in a flowerbed area), a cut-off valve may need to be installed to accurately test the domestic water lines below the slab and throughout the house. There must be no leaky or drippy faucets and the faucets must be capped or shut off. We test sewer lines by static gravity test. A test ball is placed in the main sewer line close to the outer perimeter of the house to block off the line. We then fill up the lines and monitor water level at floor level to determine if the water level drops, which indicates a leak. A "proper" clean-cut (a double or a single two-way) is usually needed to test the sewer lines accurately.
