catchment pressure tank problem

[terracore]

Thanks for everybody's input. The pressure adjustment instructions were on the inside of the cap that goes over the pressure switch. Adjust one nut and both the low and high pressure setting change, adjust the other nut and only the low cutoff pressure changes. I adjust it up so it goes back up to 50 again but when adjusting the other nut down it doesn't seem to change. So instead of being 30/50 it's more like 35/50. It fixed the pressure problem and the pump does not run as much as it used to (its back to running once each time the toilet is flushed instead of two). I just wish I could get the low cutoff back down to 30.

I might look into it more again later but for now the immediate problem has been solved so I'll got back to solving other farm problems.
