How to Replace a Well Pump Pressure Gauge?

The pressure gauge on the well pump tells the water pressure and helps in solving water flow problems. Over the years, pressure gauges start to malfunction due to blockage/buildup, or some parts may stop working. In such a situation, it is important to have knowledge about replacing a pressure gauge. Let’s read more about it.

How to Replace a Well Pump Pressure Gauge?

One Important Consideration: It is possible that the pressure gauge may not be working due to a blockage. In such a scenario, the pressure gauge can start working normally again after clearing the blockage. We suggest you do not buy a pressure gauge unless you check the problematic one.

Things Needed

  • 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 very important 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. Make sure you vent the pipe to a nearby drain or outside your home to avoid water spilling on the ground.

Step 3:  Remove the existing pressure gauge with the plumbing pliers and check for any blockages and 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 put back the old one.

Step 4: Now, you need to place the new gauge on the pressure tank’s female pressure threads and move the gauge in a clockwise direction with your hand. When the gauge becomes difficult to tighten with the hand, use pliers to tighten the gauge further.

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.


Which pressure gauge is best for well pumps?

If you are looking for a new well pump pressure gauge, I suggest using the DuraChoice oil filed pressure gauge with a maximum reading of 100PSI. It is economically priced and gives accurate measurements.

How to check that my pressure gauge is gone bad?

If the water pressure gauge glass is broken or rusted or damaged or stops responding to water pressure changes, or the water pressure never changes, understand that it is time to replace the pressure gauge on the well pump.

What is the ideal water pressure?

The ideal well water pressure is between 40-60 PSI. If the pressure is below 40 PSI, there is something wrong with your well. Either the water level has depleted, or the well equipment is not in its best shape. Water pressure levels above 60 PSI may look like a good thing, but it can result in damage to your well components.

What is the average price of a well pump pressure gauge?

A good pressure gauge will cost you $10-$20.

How does a well pump pressure gauge works?

A pressure gauge is installed on the water line between the pressure tank and the pump. It mounts on a special fitting in the waterline. When water moves through the pipe, the pressure gauge deflects and shows the current water pressure. If there is no water in the line, the reading will be zero.

Final Words

If the pressure gauge is still not working, call a licensed well pump installer to check the system for you. It is possible that there is some other issue with your well pump.
