FAQ

How do I stop my water pump from short cycling?

In order to determine if the short cycling is caused by a clogged filter, you can try the following steps. If your filter has a bypass valve, open it and observe if the short cycling stops. If your filter does not have a bypass valve, turn off the pump and the valves around the water filter. Then, remove the water filter cartridge and clean it thoroughly before reassembling it. If the short cycling ceases after this process, it is likely that the issue was indeed a clogged filter.

What causes a well pump to short cycle?

Water pump short cycling often occurs when there is a depletion of sufficient air charge in the water tank. This issue tends to be more prevalent in older homes that have non-bladder water pressure tanks.

Why does my well pump keep turning on and off every few seconds?

When the air pressure in the reservoir tank is insufficient, it can lead to problems with the pressure switch. This means that the tank may not accurately trigger the pressure switch, causing the pump to turn on and off unexpectedly. It’s important to ensure that the tank has enough air pressure to properly regulate the switch and prevent these issues.

Why does my pump keep kicking on and off?

If the condensation line is located in the upper 70 percent of the tank, it indicates a lack of air charge. This could be the reason why your pump is repeatedly turning on and off. This issue can be addressed by ensuring that there is a sufficient amount of air in the tank. This will help maintain a stable pressure and prevent the pump from cycling excessively.
