• My home inspector recommended I get a hydrostatic test. What is that?

    Mar.25.2009

    I just had my home inspected and the inspector in his report brought out the fact that the pipes under the tubs that go into the foundation are black-iron pipes. These pipes could cause foundation problems if they are corroded. He suggested a "Hydrostatic Test" to tell if there is any corrosion. What he didn't do is tell me is how these pipes can cause foundation problems and what the fix is and the cost to fix. The Home is about 42 years old. If you know please let me know.

    A hydrostatic test is used to examine the durability of your pipes, and gives us insight as to how well they are maintaining safety standards. During a hydrostatic test, we will fill the sewer lines under the residence with water, using an inflatable ball/plug at the exterior to hold the water in the sewer line. If the sewer lines can hold all of the water for typically 10 to 20 minutes, then they have passed the test and the sewer lines are deemed intact. If the sewer lines are unable to fill or they lose water once filled, then a leak exists.

    As far as foundation problems, that would be determined by the results of the hydrostatic test. It is difficult to estimate on repairs or costs without being there to examine the surroundings and the results of the test. If you haven’t already, I would suggest a licensed plumbing professional come out to inspect your pipes. If you would like to give ARS/Rescue Rooter of Houston a call, their number is (281) 777-7777.
