When I got home yesterday, three things about the cabin’s water were clear: It worked, the pressure was high normal, and the toilet valve had been leaking for quite some time. Normally that last thing would have had me worried about the level in the water tank but the gauge said everything should be fine. Therefore one of the items on this morning’s chore list was to check and see if everything was really fine…
…and everything was fine, though a good deal lower than it should have been given that I topped off the tank before I left. I’m afraid my septic system got a bit of a flush while I was gone but it probably did no harm and the tank level wasn’t so low I’d have expected to see low pressure at the gauge. I’m going to go ahead and let the tank level drop for a month or two, so I can get a better idea how that affects the pressure.
Also I think I’m going to retire the Interstate batteries in the relatively near future. None of the cells are absolutely shorted, but the specific gravity readings are all over the place. It’s hard to be sure because I have the fans on and the sunshine is kind of iffy so even though it’s near noon the batteries still haven’t gone into float which makes me think maybe I should test the charge controllers next time I have full sun. They both might be getting long in the tooth themselves, though I don’t really know what the usual service life of a charge controller even is.
I’m very happy to have had an opportunity to compare the Interstates with some badly-abused Trojan T-105s because there’s a real qualitative difference – I’m not especially unhappy with how the Interstates lasted, I always knew they weren’t top of the line, but my electrical system has come up in the world since 2013 and I won’t be buying any more of them.
In fact I might even be retiring the old Trojans before too long, since it appears an opportunity to do so might be arising. When you live ‘way out in the boonies without regular transportation, opportunities come when they come and it’s best to be ready to land them when they do.
