That's it Harvey. I thought that was what we were talking about. Didn't mean to create a thread hijack.
I have my RO running to a res. and from there I have an "Aqua Medic" auto top off unit. I only set it up very recently but so far it works really well.

Thats ok. Your pump is for input pressure, I meant pressure created on the output by a float valve closing. No pump can do that, but pressure bladders like spectra pure sells with their units will.
