How to Remove and Replace a Water Pump Pressure Switch?

This article explains the detailed steps to follow in How to Remove and Replace a Water Pump Pressure Switch

1. Turn off electrical power to the water pump. If you simply unscrew the pump control without first turning off the pump and taking pressure off of the water tank and pump, you will have a fountain of water squirting all over the place.

If you make this mistake and if you cant easily simply screw the old parts right back in to stop the leak, (youll only do it once) dont panic its just water. Just turn off the pump and open a nearby valve to take water pressure off of the system.

If the water pump pressure switch is mounted high, say on top of a well pump which is itself on top of a water tank, all you need to do is take pressure off the water tank dont need to drain it fully.

2. Disconnect electrical wiring from the water pump .

Watch out: you can be killed by electrocution. Be sure that electrical power has been turned off, confirm that power is off using a neon tester or VOM. If you are not skilled and trained in this work, hire an electrician or plumber to do these tasks.

Mark the electrical wires and their proper connection points on the water pressure control switch. If youre proceeding on your own, mark and label each wire and each terminal that it was connected to so that you can replace the wiring correctly later.

3. Remove water pressure from the water tank and pump by opening a nearby faucet or tub, or by connecting a garden hose to the water tank drain and running the hose outside. You might not need to drain all of the water out of the water tank:

4. Unscrew the old parts
Block leaking water with a finger or a pipe plug.
As you remove them and water begins to flow out of the opening where the control was mounted, the accomplice simply puts his/her finger over the hole and keeps it there while you do your control checkout or prepare the replacement to screw in its easy to hold back 5 psi with a finger over a small hole.

If you dont have an assistant, remove the old parts, and through the flowing water out of the threaded opening, screw in the pipe plug you bought for that purpose (cheap assistant) to close the leak, then go on to investigate the control or prepare and re-install the new one.

5. Replace the pump pressure control parts with the new ones or the repaired ones youve got at hand.we like to prepare the new replacement parts with pipe dope or teflon tape before taking apart the old ones that makes it quicker and neater in reassembling the pump pressure control switch with minimum water spillage.

6. Reconnect the electrical wiring to the water pump control just as the previous control was wired. For a 120V circuit, there will be four electrical wires, two line-in wires (hot and neutral wires) from the power source are connected to two screws which may be indicated as Line by markings on the switch, and two line-out wires (hot and neutral wires) bringing power out of the control and on to the water pump.If your pump pressure control switch is controlling a higher capacity submersible well pump, the electrical wires leaving the control may feed a separate heavy duty pump relay switch rather than going directly to the water pump.

7. Turn off any faucets you opened earlier to remove pressure from the water system.

8. Turn the water pump electrical power back on

9. Watch the water tank pressure gauge, and when you have about 20 psi in the system (our gauge reading shown here is a bit too high) turn the water pump power back off and check the system for leaks.

Wipe dry any wet parts, especially around the bottom of the pump control and where the pump control mounting pipe or fitting mounts into the water pump or water tank fitting.

Inspect your plumbing connections closely for water seeping out if you have leaks go back to step 1 or 2 and re-make your connections with better preparation of the threads with pipe dope or teflon tape.

10. When you confirm that there are no water leaks, turn your pump power back on and the system should operate normally.
