I'm in the process of installing a iron and carbon backwashing filter and a whole house ro setup. I'm trying to figure out what is the best way to raise my cutin pressure from the well pump so that I always have at least 40psi at the inlet to the ro machine in the house. The well and pump is about 100ft away from the house. There is currently a 40/60 ps at the well house but by the time it reaches the ro inlet at the house a 100ft away I'm only getting 53/33 approx. I need the minimum pressure to be 40psi ,will switching out the 40/60 ps to a 50/70 give me the 7psi on the low end?
I don't need the cutoff any higher than 60psi just to bump up the cutin.
The pump is a goulds 3/4hp in a 135ft well with the water level at 90ft.
I have a goulds v260 pressure tank 84.9gallons.
I tried raising the pressure on the 40/60 a little and it went up to 68 cutoff in the well house and 60psi in the house but the cut in didn't seem to move much approx. 44psi in the well house. I wasn't sure if the 40/60 can be adjusted to accomplish what I want so only tried once.
The feed to the ro is 1.6gpm at minimum 40psi so I don't need much flow.
Will the 50/70ps get me what I need and how much will it lower the 22.8 gal draw down that is currently available at the 40/60 setting. The specs for the tank don't list a 50/70 setting . Is there a formula to calculate this? Thanks for any input?
