Just non-plumbing homeowner here trying to adjust my water pressure tank. I have a well and a gould diaphragm tank for water pressure. Had been noticing a gradual loss of water pressure in the shower when toilets are flushed and made it worse the other day when I added a new bag of 80/20 mix to the neutralizer. So now the pressure drops even more so. Checked the gould tank which is currently set for 67 psi with a cut in at 45 psi. The air pressure in the tank was 32 psi. So reading that it needs to be 2 psi under the cut in, I flipped off the power, drained the tank to zero pressure and tried to use a bicycle pump to increase the air pressure from 32 to 43 psi. Naturally, the tank sits under my basement stair well, so I'm kneeling and hunched over trying to use a bike pump attached to a nozzle at the top of the tank . . . best I can do is put the pump on the wall and lean into it to pump it. After 60 difficult pumps, got it up to 35 psi and needed a rest. Can't tell if it's just my bike pump not working well, or if the bladder is far more rigid than I expected, but is it normally pretty difficult to inflate that thing? I'm concerned that if I keep working at it that I might damage the bladder . . . if not my contorted body
