HI, Got the CSV1 setup with small tank as well. Everything going great for about 2 years, then suddenly this morning after a few showers and such, water pressure went to zero. Went out and checked, things seemed normal. Checked tank, and sure enough looks like the bladder is buster or something, water coming out the air nozzle when checking air pressure. Replaced with new tank and a new 40/60 cutoff/on switch, but when turning power to pump, comes on and just goes up to about 20 psi and stops. I replaced new switch with a 30/50 cutoff switch that has the auto shut off lever on the side, and I tried to hold that down to manually keep the pump on, but again, just goes up to 20 psi and shuts off. It will then just drain to 0 psi if I open faucet and the pump won't kick back on. I just had the well pump replaced last summer and it seems to come on. Pressure holds fine at 20 psi so I don't believe I have a busted pipe/leak anywhere. Super weird. Been really happy with your CSV1A, just wanted to make sure I wasn't missing some dumb step before calling a local company to come out. Thanks!
