Today we showed up on a complimentary plumbing evaluation. Upon arrival a homeowner had standstilled water in the backyard about 6 ft away from the house. We checked and no water lines no sewer lines running that general direction. We put the house on a pressure test, and the pressure did not drop which means there is no leak on the water system. My recommendation would be to give a irrigation company a call just to check it out. Thank you for choosing comfort experts!
