Monday evening ended with the house booster pump running slightly longer than normal and sounding off, quieter. Funny how tuned into "normal" sounds one gets.
Wednesday morning confirmed water pressure too low to the house, meaning that our large storage tanks were empty. The pump wouldn't turn on manually. With a bit more digging, the coil on the contactor had infinite resistance, so it was time to call the well drillers who do the pump maintenance that I don't have the skills/parts for. Their lead Mr. FixIt is referred to as "the professor", and he definitely lives up to the name. I always enjoy learning from him. They said he'd be out on Wednesday, so I briefly hot wired the pump, bypassing the contactor to get some extra water for the cows. A few hours later I got a text telling me that the professor would be coming Tuesday and arriving shortly.
When he arrived, I got a quick grilling on the issue and my attempts to diagnose it, and then he dug in. Half an hour later we had a new coil installed, and a working pump. The old coil was cracked and looked as if it had a minor explosion inside. The nice thing about these Furnas (Siemens) contactors is that each inner component is replaceable, but there's a price for that. The UL listed backup contactor that I ordered from Amazon $26, the matching Siemens version is around $900... I'm ok putting a $26 part on the "just-in-case" shelf, but a $900 part, not so much.
I suspect that the coil took some damage in the lightning strikes that took out the microcontroller last year.
As the main water tanks were low, as in empty, I took the opportunity to chlorinate the tanks as they were filling.
I need to noodle on an alarm setup for when the pump doesn't respond to a call for water to head off empty tanks before they happen.
Not sure what I will get up to today; it might be a recovery day. So far, it doesn't look like the solar storm last night did any damage, but I haven't done the rounds yet. No visible aurora here.
All the best,
Peter
