How do you know if the pump is 150 or 95? My warranty card had 150 on it also. But I have a 95gph pump like I ordered. It has been almost 2 years now, but there was a stamped letter on the pump or housing that identified whether it was a 95 or 150. I can't remember what they were right now, memory is fading fast. I will see if I can find a post or info that I had from back then.
The pressure should be determined by the pressure spring, mine is at 18psi and that is certainly not a problem.
