Came out for no hot water. Water heater had a puddle of water under it. Was 16 years old. Water pressure tested at 130 psi. Notified homeowner and received approval to replace the prv’s and water heater. Installed a high pressure and standard pressure PRV. Set to 70 psi. Replaced water heater and tested to ensure proper function and a leak free install. Homeowner has a tenant renting their basement. He had a puddle of water in the floor that was coming up through the floor boards. We inspected the entire area as all of the plumbing lines are visible. Ran every fixture we could. No sign of where the leak was coming from. Referred restoration services for the water damage.
