If your pressure tank's jet pump isn't functioning correctly, then there are a variety of things that could be the cause. While submersible well pumps tend to be long-lasting and trouble-free, the same cannot be said for surface jet pumps. These pumps are inexpensive, and because they are cheaply made, they are prone to both electrical and mechanical issues. The good news is that you can easily troubleshoot problems with your jet pump by following these tips:
Tip: Check the Pump's Electrical Connection and Electrical Components
If your jet pump isn't running at all, then the first place to check is the electrical connection to the power panel. Since all well pumps are hardwired to a breaker, you need to check to make sure the breaker hasn't flipped. If you have had a recent power outage, then the fluctuation in power may have caused the breaker to flip.
If the breaker is okay, then remove the cover from the pressure switch to check for any burned wires. If you see any signs of burning, then the pressure switch is bad and needs to be replaced. You can purchase a replacement at your local hardware store.
Tip: Check the Pressure Switch's Water Tube for Blockage or Leaking
If you do not see any issues with the pump's electrical components, then you should check the small tube that carries water between the pump and its pressure switch. This small tube of water is used by the pressure switch to determine when to turn the pump on and off. If the tube becomes clogged or leaks, then the pump will not start or will run sporadically.
Take off the water tube by removing the attachment screws on each end with a wrench. Pull the tubing off of the screws and check it for clogging or damage. Replace the tubing with new plastic tubing of the same dimension if it is damaged. If the tubing is okay, then you can cut the ends off and push them back onto the screws.
Tip: Listen to How the Pump is Running
If your pressure tank's jet pump is running but isn't functioning correctly, then you need to listen to what it is doing. If the pump cycles on and off, then the problem lies with the check valve installed just before the pump in your plumbing. Finally, if your pump is running but it is making a clanking noise, then the pump's impeller has failed and you need to replace the pump.
