Low Pressure Air Gauge

Description

This low pressure air gauge is the only way to accurately test the air pressure in the RO holding tank. Use this low pressure air gauge to test the air pressure in the RO water holding tank and properly pressurize the tank for the best performance of your RO water pressure and volume.

Just press the gauge into the air valve on the tank and the gauge will extend. The air pressure of the tank will be the number closest to the cylinder. Use the back of the gauge to depress the air valve to let out air if the pressure it to high. Add air with a manual air pump and re-test the air pressure in the tank. The tank air pressure (on average) should be between 7 -10 psi.
