to Tighten Water Heater Connectors

If you install a water heater or have one installed, go back in six months and tighten the flex connectors on residential heaters or the dielectric unions on commercial ones. With heat and time, the rubber washers shrink a little and that often results in a leak that can wreck the heater from the outside in. Even experienced plumbers overlook this issue!
