What causes a pump to short cycle?
What causes a pump to short cycle?
The most common cause of water pump short cycling is a loss of adequate air charge in the water tank. This problem is particularly common in those homes with non-bladder water pressure tanks that are older. Similarly, having too much air in the tank (overcharging) can also cause the water tank to short cycle.
Why is my water pump going on and off?
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.
How often does a water pump cycle on and off?
Short cycling of the water pump means that the water pump keeps turning on and off rapidly whenever you’re running water at one or more fixtures in the building. The pump on-off cycle may be perhaps every few seconds, or perhaps every 10-20 seconds.
What does it mean when a water pump is short cycling?
The “short cycling” water pump is turning on and off rapidly, perhaps every 10 to 20 seconds or even more frequently. Water pump short cycling can damage the pump or controls. Repair is needed at one or more of: the water pressure tank, water pump pressure control switch, water pump, water filter, or the well or building water supply piping.
How to diagnose and repair water pump intermittent cycling?
This article explains how to diagnose & repair water pump intermittent cycling – the water pump comes on when no water is being run in the building. Intermittent water pump cycling means that the water pump comes on for no apparent reason.
What causes a well pump to cycle on and off?
Blocked Water supply Piping as a Cause of Well Pump Short Cycling A blockage in the water supply piping. For example, a clogged or nearly-clogged water filter can cause the pump control to cycle on and off rapidly. This is because the blockage causes water pressure (between the pump and the filter) to rise very rapidly when the pump turns on.
