Regular water heater maintenance vital for longevity

Water Heater Maintenance

You may not give your home’s water heater much thought until it’s no longer doing its job providing hot water, so to avoid that dilemma the experts at Harco Plumbing and Mechanical in Cambridge have some maintenance tips to help extend the life of your hot water heater, saving you money and hassle.

Water heaters can last for more than a decade, so keeping them properly maintained annually is important. Before attempting any type of maintenance, however, be sure to turn off all power to the appliance to avoid any possible electrical shocks.

Dialing down the temperature to between 115 to 120 F will protect the tank from overheating and reduce the energy used. Test the temperature and pressure relief valve and open the drain valve to let water run for 30 minutes once a year.

Removing sediment from the bottom of the tank is important to prevent rust, corrosion and to improve overall efficiency. A full flush is suggested, but requires shutting down the heater. A mini-flush works well by turning the valve counter-clockwise to release a few gallons of water into a bucket, then closing the valve again.

If you have a sump pump chamber, test in the spring and the fall to make sure it turns off and on. If you have any outdoor hose taps, shut off the valve on the inside and drain by November.
