Is your sump pump going off regularly without anything happening to set it off? If your sump pump alarm keeps going off, you may need to change something to make sure it only goes off when there’s actually a problem, and not for false alarms.
Make sure there aren’t any ways for water to get on top of the sump pump. If your sump pump is in a particularly unlucky space, water could pour on top of it in certain situations. You should also check to see whether the sump pump alarm is going off for a good reason. If it is, but it’s going off too frequently, you may need a more powerful pump.
If your sump pump alarm is going off because your power has gone out, then you may want to think about investing in a battery backup. The battery backup makes sure that your sump pump is still working, even when the power is out.
