If drawdown (amount of water available per cycle)
decreases significantly, check as follows:
1. To check air charge in tank, shut off electric power to

2. At the air valve in top of tank, check air pressure with
standard tire gauge. Air pressure should be 28 PSI.

3. If the air pressure is below 28 PSI, add air to the tank.
Use an air compressor or a portable air storage tank.
4. Use soap or liquid detergent to check for air leaks
around air valve. Continuous bubbling indicates a
leak. If necessary, install new core in air valve. This is
the same as those used for automobile tubeless tires.
