It’s not fun, but it will end and things will get better. Hang in there.

I would go check it daily with some 300 or 600 grit sandpaper. That got boring in a hurry.

No probs since the pump house was built. I sure wish the real estate agent wasn't so dismissive of it. Said it snows every ten years. (It snows 2 or 3 times a year here) and I had heat tapes installed at the same time.

I still carry sandpaper.

I have a two stage system with submersible pump and 2000 gallon storage tank. Must be a county fire code because everyone has one. Two pumps, each with a protection box. Quite the engineering feat.

Glad your switch was fixed. I know the feeling too "well". I keep contact cleaner spray on hand. Good for amps, radios and jacks. Avoid wd-40 for electrical work. It has paraffin in it, IIRC.

Mines under the crawl space. real pain going thru the window and on my hands and knees.
Just replaced the septic a month or so ago $11K.

I did have smaller parts such as the switch anf gauge replaced a while back. New protection box for the booster pump and new electrical panel (It's outside and breakers were oooold, even if boxed up )

Can you clean contacts, not just spray with solvent? My equipment is above ground away from the house though. 300 or 500 grit sandpaper is what I used to use. Power off!!!

Pump houses here look like outhouses. Much more pleasant.

Good luck.
