Nate, is yours a permeate pump?.... it should only have isolated the membrane outlet from building up over 5psi back pressure on the membrane.
To be honest, I love mine... efficiencies went way up, water usage went down and prefilter life went way up
They are only useful with systems that use the air tank though... as the air tanks fills with water the back pressure on the membrane outlets goes up and up. This increase in back pressure results in a decrease in pressure differentail across the membrane. This results in a proportional drop in rejection ratio, commonly known as "creep". Also the brine rate goes up proportionally as well, wasting water.
Can you verify what type of pump it is?
It seems like you are referring to a booster pump which is totally different, has a different purpose and would be plumbed totally different.
Permeate pumps do not build up additional pressure, they only isolate
