It's April 4th, the ground around our foundation just thawed

A consequence of that is that the sump pump is going into action for the 1st time in months

And the 'action' has had a bit of trouble. We have a double pump system, one pump usually runs, the other runs as a back-up. Mid afternoon the alarm went off. The primary pump wasn't working as the processor in the controller expected.

I thought maybe the contacts tripped by the rising of the 'floats' was somehow dirty or corroded. I played with lifting and dropping them multiple times. The alarm went off, and the primary pump started pumping... All good, at least so far.

So, I'm sending out a precautionary note to you fellow Wisconsinites. Spring has finally reached southern Wisconsin. It will probably reach you very soon.

You may want to do a routine sort of checking of your sump pump(s).

May your basement always be dry!

That is all.
