While there is no set optimum run time for a sump pump, there are some guidelines you can follow to ensure the pump runs at an ideal cycle. For efficient pumping, the unit should be able to operate comfortably. An optimum sump pump run time is when the unit has a good flow rate and pumps effectively without placing too much stress on the pump.
Understanding Sump Pump Operation
Different sump pumps can operate in various ways. A duplex station controlled by a lead panel operation is typically designed for 10 startups per hour. Grinder pumps are intermittent-duty pumps, so they’re not ideal for applications needing long operating cycles.
The primary purpose of any sump pump is to move excess water from a property’s basement to another area. If there’s too much water and the pump doesn’t have adequate basin or pumping capacity, and vice versa, it may affect the run time.
What Is the Ideal Sump Pump Run Time?
It’s best to avoid short cycle times, which can place undue pressure on the pump. Fifteen to 20 cycles per hour could overheat the pump and the starting components. A longer cycle time is OK if the pump is designed for it.
Ideally, you want to set a minimum target of one minute or longer cycle time, with a rest period of at least five minutes between each activation.
How to Adjust Your Sump Pump Run Time
As there’s no set run time, ensure the pump can handle the application. Get a basin of a suitable size in relation to the amount of water being pumped, and modify the pump’s operating range to achieve a good balance. You can adjust the pump’s run time by doing the following:
- Ensure the pump can accommodate the size of the area effectively.
- Get a larger basin diameter if you have a large area or the pump’s run time is too short.
- Get a backup sump pump if you have heavy-duty applications.
- Adjust the pump’s on/off operating range to avoid short cycling times.
- Check the sump pump’s float switch.
