If your well pump has lost prime, you should first check for any leaks in the system. Next, try to reprime the pump by adding water to the pump through the priming port. If this doesn't work, you may need to call a professional well pump technician to help troubleshoot and fix the issue.
Did you "RE-PRIME" the pump after you changed the pressure control switch? A likely reason you are not getting water would be that the pump "PRIME" was lost when you changed the pressure control switch. Pump seals can be burned up quickly if you run a jet well pump with no prime (lost prime) and will cause them to leak around pump shaft.
If you have a pump well, your holding tank may be flooded, and you will need to drain your tank and then refill it and it should hold its prime again. When a tank is flooded you will often hear your well's motor kicking on and off repeatedly.
Your pump lost its prime. Could be a bad seal in the pump head, a bad check valve, a leak in the suction line, or a dry well.
On well water, there is sometimes a reservoir that needs to refill. So if water stopped coming out of your tap, normally you just have to wait till it refills. IF YOUR PUMP IS RUNNING & NO WATER YOU COULD HAVE A LEAK IN LINE FROM WELL TO PUMP.THE PUMP SHOULD PUMP UP PRESSURE & THEN LEAK BACK DOWN IN PRESSURE. I HAD THE VALVE GO BAD AT THE END OF LINE IN WELL & INSTEAD OF PULLING LINE FROM WELL, I INSTALLED A VALVE AT PUMP THAT LEAVES WATER FLOW FROM THE WELL, BUT DOES NOT ALLOW WATER TO LEAK BACK TO WELL. A SIMPLE FIX. FIRST, DID YOU TRY PRIMING THE PUMP BY FILLING WATER PUMP THROUGH THE PLUG ON THE PUMP & 2ND. ARE YOU SURE THE WELL IS NOT DRY. IF YOU PRIME THE PUMP WITH WATER & IT PUMPS NOW THE WELL WATER IS OK,BUT IF IT LEAKS DOWN & LOSES THE PRIME, THE FIX ABOVE WILL REMEDY THE PROBLEM.
Your well pump may be losing prime due to air getting into the system, a leak in the pipes, or a faulty check valve. To prevent this issue, regularly check for leaks, ensure the check valve is working properly, and consider installing a priming device to help maintain prime in the pump.
If you are using a jet pump you must have a good foot valve, then remove the prime nut or gauge from the top of the pump and fill the pump and pipe with water. You may have to do this a number of times to get all the air out of the system.
A foot valve, in relation to a water well, is a check valve at he bottom of a well to keep the water from running back into the well from the pump when the pump is not running. If the check valve does not hold the water the pump will lose it's prime and will not pump water.
If the well pump is not holding a prime and spitting out dirt, it could indicate that there is an issue with the pump's seals or valves causing air to enter the system. Additionally, the presence of dirt could suggest that there is a blockage in the water supply line or the pump itself. It is advisable to inspect the pump, check for leaks, and clean or replace any clogged components.
There are a number of problems that might cause a well not to produce water. There could be some kind of electrical problem and the pump might not be powered up. Or the motor for the pump may have failed. The pump may have lost its prime and cannot pump water (depending on the type of pump), and the water table might have become lower and the pump is now above it and dry. Think about how the pump worked before, and how it works now, and then compare the two "observations" to see if there are any differences. Does the pump sound like it comes on? Open a tap and, while listening at the tap, have someone turn on the pump. Troubleshoot this and return with a more specific question if you can.
When a shallow well pump loses prime, first check for any visible leaks in the suction line or fittings that could allow air to enter. Next, inspect the foot valve to ensure it's functioning properly and not clogged or damaged. Additionally, verify that the water level in the well is sufficient to maintain prime. Finally, check for any blockages in the intake screen or the pump itself that could impede water flow.
A shallow well jet pump sits on the ground next to the well. To install it, connect tubing to the intake side of the pump and put a foot valve on the end of the tubing to control the water. Lower the foot valve and tubing into the well. Remove the drain plug on the pump and pour water in it to prime it. Replace the drain plug, connect the pump to power and turn it on.
Perhaps it has lost suction - is there a re-primer switch or handle on it ? Try re-priming your pump if it still doesn't work it needs a proper check.
