I canít explain the pump only aspect, but there is supposed to be an air cushion in the top of the water heater. I canít remember the exact procedure to restore it, but if you disconnect from city water, turn off the pump, and pull the drain plug on the heater until it empties that should do it. Then replace the plug, hook up to city water and open a hot water faucet until the tank fills and water comes out of the faucet.

The manual for your heater should have the exact procedure.

That is the exact procedure. Never lift the pressure relief valve lever to fill the tank. Run a hot faucet until it quits spitting air is the correct way to fill the water heater.

Here is the procedure in my Atwood Manual for restoring the air gap using the pressure relief valve:

"TO REPLACE THE AIR GAP FOLLOW THESE STEPS:
1. Turn off main water supply (the pump or water hook up source).
2. Let water cool or let run until cool.
3. Open the hot water faucet closest to the water heater.
4. Pull handle of pressure temperature relief valve straight out and
allow water to flow until it stops.
5. Allow pressure temperature relief valve to snap shut; close faucet;
turn on water supply.
6. Turn on water heater and test."

The manual also suggests using the pressure relief valve when draining the tank for winterization.

The procedure quoted from the manual may result in a smaller air head at the top of the water heater IMO. The steps outlined by Al and Rich are a better method IMO.

Our water heaters are basically the same as residential units, and most plumbers would follow the more complicated procedure, not the AS manual.

BTW it is not necessary to empty the water heater completely, just to get the water level a few inches below the PRV. This means you have to re-install the plug at the bottom as water is still draining out. If it is lukewarm, and you shut the PRV, not a big deal.

Agree to disagree.
