the alarm keeps coming on for ten second before it starts pumping

This is a little cryptic.

This would be better posted in Plumbing, but here goes anyway.

If there is water coming in continuously, and there are two pumps, most likely the lead pump has failed, and the alarm goes on until the lag pump has lowered the sump level.

The control logic might also sound the alarm when the lead pump is called for, but does not respond. The alarm is sounded for 10 seconds, then the lag pump starts.

Just two possibilities, with more info, we could be more helpful. How many pumps? How many floats? Age of system. Type of control.

Could be that the alarm switch is set to activate before the pump switch. The alarm switch might need to be set higher or the pump switch lower.

how old is the system?

what brand is the pump?

does it have floats? if so, how many floats?
