Water Pressure Tank Air Valve

Use a small screwdriver to depress the air valve to see if water comes out.

Water pressure tank air valve.

A common cause is a failed check valve. Adjust the pressure with an air compressor if necessary. Water tank air inlet valve schrader valves. A new tank costs about 200 and up.

Choose from a valve for air inert gas water hydraulic oil fuel oil gasoline or diesel fuel and a set pressure from 150 to 3 300 psi. The air inlet valve on a bladderless water pressure tank may be at any of several locations. Bleeding air out from the tank top will prove a short remedy and pressure will creep up again. Near the tank top on the tank side on a tee at the bottom of the water tank or on well piping nearby.

If the valve fails water streams back down the well and the pressure switch turns the pump on again. Check the pressure tank s air valve. Unscrew the plastic cover from the air valve on the top of the tank. When water pulses at the spigot it usually means you have a waterlogged tank.

The check valve or foot valve prevents the well pressure tank from sending water back down into the well after it has built up with water pressure. Water tank pressure measured at the air gauge or schrader valve on the tank top will creep up to above normal levels. Pressure relief valves for water these valves are commonly used with pumps in low pressure water systems. Design a valve specifically for your process media and set pressure.

Check the air pressure in the water tank by using an accurate air pressure gauge such as a dial type or digital tire pressure gauge to measure the air pressure at the schrader valve on the water tank. Captive air water tanks that use an internal bladder to keep water and air separate such as the well x trol water pressure tank will display an air valve usually on top of the water tank and often red in color such as shown in this photograph. At left is an air inlet valve located on the tank tee near the bottom of what was a bladderless water pressure tank. Unscrew the cap covering the valve and press the tire gauge down on the valve.

On composite tanks the valve can be found toward the base of the tank. The internal water tank air valve stem part valve stem core that is replaced can be purchased with different spring strengths for different pressure ranges but in fact given that the pressure range of a typical water tank is 20 70 psi like a car tire almost any common tire valve stem core would work fine as a replacement if your valve stem won t stop leaking.
