At what level does your catchment have to be....

Beachboy,
Check your water filter your pressure will decrease by half if it is plugged up.

what should pressure be at for a 20 gallon tank? Currently pressure gauge says it's right below 40 psi

Within reason, the pressure is what you want it to be. To me, 40 would be good for a cut-in pressure, with 60 for a cut-off. The higher the range the more stress on the pipes, but it makes for more pleasurable use, but also heavier use. Most switches are preset at a reasonable level and it is not recommended to adjust some switches. Normally, the empty (of water) tank pressure would be about 42 for a switch setting of 40.

I just got my spare (yes I always have a spare) switch off the shelf. It's a Square D brand (Pumptrol) and it does come set for 40/60. It is adjustable.

If you are getting a reading of 40 on a waterlogged tank it doesn't tell you much. Water doesn't compress. You must have that head of air to get usable water pressure.

P.S.
A 20Gal equivalent bladder tank is, IMHO ridiculously small. That is the size I would expect to see on a small irrigation well used just as a buffer for the irrigation pump. But then I'm not on catchment and there may be catchment issues I'm not aware of. I have been dealing with well water for 25 years.

Also, I can't advise on costs as I don't know. You do get what you pay for and Home Depot is probably not the best place for a punp. They also don't cary the best tanks but the pump is usually a larger investment. I can't recomend a pump as your use is different from my experience. I'm sure you can get by with much less of a pump than me as I have a much greater lift as I have a well.

My bad! It's actually a 42 gallon tank! Since this is not my house, I called owner and informed her of situation.
Went out to garage yesterday afternoon upon returning from Hilo and noticed a new system. Not setup yet, but let's see what happens. It's a 42 gallon Flotec with a 1/2 hp pump from Flotec..
