The anode rod helps reduce corrosion and extends
life of the water heater. Turn off power (or gas).
Turn cold water supply off and relieve pressure in
tank. Remove anode rod with 1 1/16” socket and
impact wrench. Replace if significantly depleted
(flexible replacement anode rods are available
if overhead clearance is tight). Check the anode
rod at least every three years depending on local
water conditions. Units with a water softener
should be checked annually.
Plumbing codes have always required an
expansion tank on closed plumbing systems.
Operating a water heater on a closed plumbing
system without an expansion tank will damage
the water heater and other appliances. Pressurize
expansion tank with air before installing on
cold water line. Air pressure should match water
pressure.

Most experts recommend setting the Pressure
Reducing Valve to 50-60 psi to protect appliances.
High water pressure can damage water heaters,
toilet valves, ice makers, dishwashers and washing
machines. A dripping Temperature and Pressure relief
valve often means the water pressure is too high.
Drain and flush tank (very important for gas water
heaters). Turn off cold water supply, and open drain
valve. Open T&P relief valve to relieve pressure.
Drain 2-3 gallons of water. If water is milky, drain
entire tank. Close drain valve and open cold water
supply valve. Open a hot water faucet and let hot
water run 3 minutes to make sure all air is out of
tank before returning to service (very important for
electric water heaters).
