I had a hydrostatic plumbing test performed on my house by the Master Plumber, Alfredo Vallejo. He did an excellent job! To properly pressurize and test the sewer lines, he had to remove a toilet. After allowing sufficient time for the test, he promptly shared the results—much to my relief, everything passed! He also inspected the inside of the sewer lines with a camera and showed me the video footage. He noticed that the wax ring beneath the toilet needed to be replaced and took care of it without hesitation, which was truly above and beyond. He was professional, thorough, trustworthy, and highly recommended.Posted on Google![]()
