How We Repair Your Instant Hot Water Dispenser
Tank and tankless water heaters, instant hot water dispensers and recirculation pumps heat water with gas burners or electric elements controlled by thermostats and safety devices.
Safety first: Water dripping from the relief valve can mean too much pressure or temperature. Have it checked promptly.
