A leaking water heater required complete replacement at this Zephyr Cove property. Riley Plumbing Heating And Air drained the system, disconnected the failed unit, and removed it for disposal. The crew installed a new 50-gallon natural gas water heater with a protective drip pan. A two-gallon expansion tank was added to accommodate thermal expansion in the closed system. New three-quarter-inch shutoff valves were positioned on both supply lines. The gas connection received a new valve and flexible supply line meeting current code requirements. Copper supply lines replaced the old connections. The system was pressure-tested, gas connections were checked for leaks, and the unit was fired for operational verification. Expansion tanks prevent pressure buildup that can damage fixtures and connections. Properties without them experience reduced water heater lifespan and potential valve failures throughout the plumbing system. If your water heater installation is due for replacement, book an appointment to discuss proper sizing and expansion tank requirements for your home.
