How to Fix a Waterlogged Well Water Pressure Tank. Your pump is running almost constantly and you figured out that it is because your tank is waterlogged. A waterlogged pressure tank on your well system leads to pump motor burnout, so you need to correct the problem and fast. Here is how to fix a waterlogged well water pressure tank to keep an expensive well pump in good working order.
Turn off the power to the pump. The pressure gauge on the tank will cause the pump actuator to kick in if you don't. Find the breaker for the pump and flip it if your pump does not have a power switch.
Attach a garden hose to the drain on the tank. You will usually find this at the bottom of the tank on most models.
Open the valve and drain all the water out of it. Depending on the size of your tank, this may take a few minutes.
Shut the valve. Check the air volume control, if your tank has one. Also check the pump actuator and be sure the setting is right for your tank and pump.
Flip the breaker or switch to turn the power back on to the pump.
Listen to the pump. If it is still short cycling, meaning turning off and on in rapid succession, you may have a bad bladder in your tank and you might need to replace it.
