Tank Flushing Procedure
1. Shut off electrical power to the heater and disconnect the cold water supply.
2. Completely drain the heater and remove the drain valve.
3. Install a 3/4” x 6” nipple with a garden hose adapter into the drain valve spud (opening) and run it to
the floor drain, a bucket, or another method of removing water from the work area.
4. Use a straight adjustable spray nozzle (set for a wide angle) attached to a garden hose. Insert the
nozzle into the cold water inlet spud and wash down the interior sides of the tank. this will remove any
particles that have adhered to the sides of the tank. Slowly begin to lower the nozzle into the tank
until it reaches the bottom. Repeat this process several times to be sure the interior walls are clean.
5. Close the drain valve, refill the heater and return it to service.
