Hey
Been reading a bunch of posts here, think I have it somewhat figured but looking for some guidance. Looking to get a more ‘constant’ pressure from my well. Current setup is a 40~ gallon pressure tank, Franklin 1/2hp 5gpm submersible. 30/50 psi pressure switch. All located in the basement of the house. Going to be trenching over to a barn in the next couple weeks from the well, teeing into the existing line/hydrant. Well is 105’ deep, pump landed at 85’, static water level 17’. Pitiless adapter at 10’. Flow tested the well at 5 gpm. Looking at the csv12550, would you recommend leaving pressure switch at 30/50 or going to a 40/60? Or would a csv12560 be better with a 40/60 pressure switch. Looking for 40-50 psi for showering etc. Thanks in advance!

With only a 5 GPM pump your pressure problem could be from a lack of flow instead of pressure. A 10 GPM, 1/2HP would be a much better fit for such a shallow well. A 3/4HP, 10 GPM would be even better.
But you can get what you can get with the 5 GPM pump. That pump lifting from 17' can make 155 PSI, which is 5 PSI higher than we recommend for the CSV125. We have some fudge factor figured in, so it will work. But the higher the pressure setting the better. You can use a 50 PSI in the CSV125-1 with a 40/60 switch. But you have plenty of pump pressure to turn up the switch to 50/70 and use a 60 PSI CSV125-1. If the 5 GPM volume is not your problem, the 60 PSI pressure would be such strong shower pressure than soap would no longer be needed. Lol!
