I do not know exacly but I would pick the lowest possible. The plastic lines do not like high pressure. I have and inside pressure relif and I hook up one on the hose to lower it more.

I think many of the fixed pressure regulators are set around 42-45 psi. I set my adjustable Watts unit at 54 psi and the tag on my internal Watts unit says 45 psi best I can remember.
