Question: How To Stop Pressure Tank From Short Cycling?


Why is my pressure tank short cycling?

Loss of air charge is, perhaps, the most common reasons your water pump will short cycle. If it’s in the upper 70% of the tank, then that means there’s not much air reserve, and likely this is the cause of your pump short cycling. To fix this, first make sure the air volume control valve is not dirty or leaking.

Why does my pressure pump keep running?

A well pump that repeatedly loses its prime likely has underlying problems. In many cases, the problem stems from a leak in the drop pipe. Other common causes include air leaks in either the impeller or the pump casing, faulty check valves inside of the well pump, or a damaged foot valve at the bottom of your well.

What causes a pressure tank to lose pressure?

A common cause is a failed check valve. The check valve or foot valve prevents the well pressure tank from sending water back down into the well after it has built up with water pressure. Another very common issue is the pressure tank losing its captive air pressure.

Why won’t my pressure tank fill with water?

How do you check a pressure tank switch?

Check and clean the switch relay contacts. Examine the four contacts for burning or pitting on the surface. If you see signs of damage, you may need to replace the pressure switch.
