Customer had a leak coming from free standing tub faucet on the hot side. Customer stated her husband had tighten the union on the faucet where it was leaking. I turned the water on to the faucet and checked for leaks. Ran the tub multiple times and could not replicate leak. Checked the thermal expansion tank which was good. Checked the whole house incoming pressure which was on the high side reading 75-77psi. Replaced Prv and brought pressure back down to a safer level of 65psi. After install I pressurized the system, checked for leaks and proper function, everything is good as of right now. Thank you for choosing te certified
