For this job, it was required me to verify that a thermal coupling was tightly secured to the gas valve on our clients water heater and was safe to light. Second item was high water pressure management. Our client has great poly pipe within home. Most of the fixtures have been re-piped except for the items underneath the slab. At the beginning of the visit, the water pressure was 80 psi and after the replacement the new water pressure reading is 50 psi. A client is very satisfied with our service today
