Make certain the drain valve is
completely closed.
Open the shut-off valve in the cold water
supply line.
Open each hot water faucet slowly to
allow the air to vent from the water
heater and piping.
As the water heater fills, air will be
pushed from the open outlet faucet. A
steady flow of water from the hot water
faucet(s) indicates a full water heater.
Check the tank and cold water lines for
leaks and repair any found.
Ensure that the storage tank is completely
free of air by opening the T/P Valve until
it discharges a steady stream of water.
Then close the valve.
The system is now ready to Test and Fill
