Came out for a leaking expansion tank. Water pressure tested at 100 psi. Front hose bib was leaking constantly. Received approval to replace hose bib and PRV. Customer elected to replace water heater since the expansion tank was included in that service and his water heater was from 2014. Installed new water heater, PRV, and hose bib. Tested to ensure proper function and a leak free installation. No further issue at this time.
