As a follow up to our annual inspection we needed work done on some very old pipes and connections to the water heater. Service people arrived promptly and were very courteous and professional. Everything went smoothly and the water to the house was off for only a short time. They cleaned all. The lines of residue to assure adequate flow. I forgot to have them check the line to the refrigerator and about a week later when I realized the flow was diminished but the filter was fine, I called to have them come back. Haven't seen them yet.
