Water Pressure Tank Air Valve

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.

Water pressure tank air valve.

A new tank costs about 200 and up. Water tank air inlet valve schrader valves. 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. Design a valve specifically for your process media and set pressure.

Use a small screwdriver to depress the air valve to see if water comes out. The tank pressure should be within 10 of the original factory water tank pressure setting. Check the pressure tank s air valve. 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.

Pressure relief valves for water these valves are commonly used with pumps in low pressure water systems. Water tank pressure measured at the air gauge or schrader valve on the tank top will creep up to above normal levels. A common cause is a failed check valve. The air inlet valve on a bladderless water pressure tank may be at any of several locations.

Replacement is your only option. When water pulses at the spigot it usually means you have a waterlogged 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. Unscrew the plastic cover from the air valve on the top of the tank.

On composite tanks the valve can be found toward the base of the tank. 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. If the valve fails water streams back down the well and the pressure switch turns the pump on again.

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. Adjust the pressure with an air compressor if necessary.
