The pressure gauge on the well pump tells the water pressure and helps in solving water flow problems. It can go bad due to blockage/buildup, or some other reason. The good part is that you can replace the gauge yourself.
Just a Pro Tip: It is possible that the pressure gauge may not be working due to a blockage. You can use try the same gauge after cleaning it. We suggest you do not buy a pressure gauge unless you check the problematic one.
- Replacement pressure gauge
- Garden hose (you may already have one)
- Teflon tape
- Channel locks or plumber pliers
Step 1: Turn off the water pump by removing the electrical wire and then turn off the circuit breaker. Safety is critical while doing such DIY tasks.
Step 2: Turn off the water supply to your home and drain the water from the pressure tank using a garden hose.
Step 3: Remove the existing pressure gauge with the plumbing pliers and check for any blockages or buildups. You must remove the gauge by holding the brass fittings below the gauge. Move the gauge in an anticlockwise direction. If there is no buildup, get a new replacement gauge. Otherwise, remove the blockage or sediment buildup and test it if it works now.
Step 4: Now, you need to place the new gauge on the pressure tank’s female pressure threads and move it in a clockwise direction with your hand. Tighten it further with pliers.
Step 5: Remove the water hose and close the drain spigot.
Step 6: Turn on the water pump and observe the pressure gauge. If it responds to the change in pressure, you have successfully replaced the pressure gauge. Turn on the water supply to your home.
