I just filled my water tank and checked pump... it worked, phew. So
this is one case of pump surviving freezing, lucky.

Noticed my level indicator lights were weak and inaccurate. Turned out
to be less than tight spade connector (black wire?) at bottom. I had
gone over the entire water supply system last summer and had it
working well, must be a fatigued female spade.

This is for the old style, resistance based, water level system.
