"My automatic pump stops and starts constantly, how can I make the pump run longer?"
A pump short cycling is a function of the basin diameter and the "on/off" pumping
range. Since the basin is in the ground it is unlikely that it can be enlarged. If you have an automatic unit which has a self contained float switch the "on/off" pumping
range cannot be adjusted. But with a nonautomatic unit controlled with a pump switch you can have flexibility in the pumping range adjustment. Short-cycling can decrease
the service life of a switch assembly. If this occurs, an automatic unit can be converted to operate with an external pump switch which will expand it's pumping range and
decrease the amount of short cycling. Installing a check valve in the discharge line will help decrease short cycling.
