As a rural homeowner utilizing a deep well pump, it's easy to be frustrated when it stops moving water to the surface. After all, it's not like you can simply look at it and figure out what the problem is since the pump is located hundreds of feet below ground inside of your well.
Since you can't see or handle a deep well pump, troubleshooting requires using a process of elimination to figure out why it isn't working. So, if your pump isn't moving water, then try each of these three things:
1. Make Sure the Pump Has Power
Sometimes a momentary power fluctuation will cause a breaker to flip and disconnect a submersible well pump's power supply. While this is actually a good thing because it protects the pump from permanent damage, it can also be frustrating if you don't notice the breaker has flipped. In fact, many homeowners have called out a well driller for a service call only to watch them open the electrical panel, flip the breaker, and restore water flow.
When troubleshooting submersible deep well pumps, the first thing you should always do is make sure the pump has power. If the breaker is off, then flip it back on and keep an eye on it to ensure you don't have a more serious problem. If the breaker is still on, then move on with the troubleshooting process.
2. Check the Surface Electronics for the Pump
Located in your pumphouse or somewhere near your well, you will find a metal box that contains all of the surface electronics necessary to make the submersible well pump function. Inside of this weatherproof box, you will see a small electrical board, a few wires, and a cylindrical capacitor.
If you see any indication of burning or melting of either the electrical board or wires, then your pump may need to have its surface electronics replaced. Thankfully, this can typically be accomplished without having to pay a well driller to pull the pump out of the ground.
If everything inside of the box looks fine, then it's entirely possible the capacitor has failed. A well driller or electrician can easily replace the capacitor for you and get your pump back into working condition in just a few minutes.
3. Hit the Reset Button On the Surface Electrical Controls
Inside of the box containing the surface controls you will also find a reset button. Push this button once and then wait a few minutes to see if that starts the pump. If it does, then you are back in business. If not, then you will need to call a well driller such as Modern Pump & Equipment for help.
