Arrived and found water leaking from main inlet to water heater and tee fitting leading to it. Replaced tee fitting and copper lines leading to water heater Ensured no leaks with replaced fittings and pipe, NOTE! Shut off valve leading to water heater started leaking when opened (did not touch this fitting other than to open water to water heater) Customer was given a quote to fix this issue and wants to possibly get this taken care of during the scheduled heating tune up.
