When your deep well jet pump conks out, it can be quite difficult to repair due to the fact that it is located underground. It can be buried around 200 feet below the surface so repairing it can be a problem. That’s why it’s important to troubleshoot the jet pump thoroughly before digging it up and possibly wasting your time, effort and resources. It should also be addressed immediately especially if it is your home’s sole source of water.
If your deep well jet pump has ceased working, try checking the electrical system first. Go to the main circuit breaker and check that the switches are in the “on” position. Sometimes the switches get switched off automatically when there is a spike in electrical current. Check also the fuse since it might have blown. If this is the case, bring the blown fuse to your local hardware store and get a replacement, using it as your sample. Having taken these steps, hopefully the pump will start running again. If it still doesn’t work, inspect the fuse box and the wires coming from the well, since the problem could be with these. However, if you have already checked all of these points and the jet pump still doesn’t run, you may have to move to the pump itself.
If the motor of your pump is not running, as stated earlier, it can also be connected to the wiring on the surface. Be sure to thoroughly check that portion. However, it is also possible that the cables found within the pump have been damaged. The starter could also be at fault. These should therefore be replaced immediately. The problem could be the motor itself getting stuck due to dirt and corrosion buildup from underneath the ground. In any case, you need to bring the pump up in order to replace these components, which could be quite tedious.
There is also the case wherein the jet pump motor is running, but there’s no water coming out of your faucet. This could be the result of several factors. First, remove the priming slot on the pump and check if there’s water that comes out. If there’s water, that means the pump is properly primed. If no water comes out, that means that the pump needs to be put through the priming process again. This will only take a few moments. Another problem could be that the pipes are clogged. The pipe or strainer could be clogged and the pump is sucking dirt and mud. Also, inspect the check valve of the jet pump. It may not be working properly and be sending water back into the pump causing it to drown. Water that should be going to the house is being shoved back down into the pump. If it’s winter in your area, the pipes connected to your jet pump may also have frozen, restricting the amount of water passing through the system.
