Water Tank Pressure Gauge Not Working

If your pump seems to be cycling turning on and off repeatedly there are a few common causes.

Water tank pressure gauge not working.

The pressure gauge is a great tool. Pressure gauges also known as tire gauges read the pressure of the tank by using a piston to propel a calibrated spring when exposed to pressurized air. If your tank doesn t have enough pressure the valve won t work and water will keep flowing in and down the drain. Turn off power to the well pump and run water after the pressure tank or in the house until there is no water pressure left.

Using a tire pressure gauge check the schrader valve on top of the pressure tank. Water pressure gauge faqs recently posted questions answers about water pressure gauges. Now any water used in the house is coming directly from the newly filled water supply in the tank. Thanks for the follow up that will help other readers.

Switch clicks on and off repeatedly. Once the pressure reaches the high point the pump stops running. If you find that your pressure gauge is not working no worries. The pump starts sending new water to the tank.

This is easy to check. Typical residential water system pressure gauges found at the water tank or water pump are only approximate and are not lab instrument grade but the water pressure gauge is a very helpful diagnostic when you re diagnosing a loss of water pressure or pump operating problem as well as when you re adding air to a water tank. Aside from checking the pump check your water pressure gauge to ensure that it s working before diagnosing a pressure switch issue. Use the gauge to check the tank s pressure.

Another very common issue is the pressure tank losing its captive air pressure. As water fills the tank air pressure should increase steadily to 35 40 psi which triggers a check valve that stops water flow into the tank.
