Expansion Tank Pressure Switch

Use a tire gauge to check the pressure.

Expansion tank pressure switch.

Most households are set up to run with a pressure switch that turns the pump on at 30 pounds of pressure and turn the pump off at 50 pounds of pressure. Close off all plumbing fixtures that are using water in the building. Open one or more plumbing fixtures to drain the water pressure tank. During this draining watch and listen to the water.

Most expansion tanks come pressurized to 12 40 psi but before you install the tank you have to match the system pressure. Future bk king ultra. If you do have another check valve then you would need an additional expansion tank also. Start by removing the protective cover from the air valve on the tank.

Use a bicycle pump or compressor to fill the tank to match the system pressure you noted earlier. A bladder expansion tank is a system which is used for heating and cooling purposes by absorbing the expansion force. Most expansion tanks come pressurized to 12 40 psi but before you install the tank you have to match the system pressure. Turn on the water pump and let the system run until the water pump cuts off.

Start by removing the protective cover from the air valve on the tank. It informs the well pump when to turn on and when to turn off based on the rise and fall of the pressure within the tank. It uses compressed air to adjust with the pressure changes by eliminating or accepting the water volume changes as it expands or contracts due to heating and cooling. Use a tire gauge to check the pressure.

A pre charged bladder tank is an expansion tank which is already charged with air. Here is the procedure. Use a bicycle pump or compressor to fill the tank to match the system pressure you noted earlier.
