Ouch, throw out my “analysis” of your system...it was based on the high gpm. I’m with Bama Rambler (and you), your new pump is definitely a smaller horsepower than your old one. The actual GPM number is probably much lower than 95gpm. One reviewer on amazon for your pump indicated a significant drop in gpm when they used it to replace a similar rated pump in their system (they had a flow measuring device)...I would post but I can’t find it again. There are no pump curves available for your pump so it would be difficult to find the real gpm. Mas985 would be one who might have an answer.

It works (so far), but with conditions. I purchased a used one from Amazon warehouse, if came in with original box and packing materials, looked new except it was not prewired for 230.. no problem. I could have looked it over real good before installing because after firing it up and troubleshooting air leakage I found a crack in the housing guess I just found why someone returned it. I siliconed the crack and up and running with low air leakage. I have a flow meter on my pool equipment (if you don’t and do your own maintance... GET ONE). With my Pentair WhisperFlow 2hp my flow is 88 to 90 GPM, with the 2 hp Xtremepower pump I’m getting 60 GPM, no other changes. Needles to say I will be rebuilding the WhisperFlow PDQ. Would I purchase again, for what I did and needed No, I would have just purchased all the parts to rebuild my failing WhisperFlow because I did not realize how inefficient this pump was. Good luck all

Joe, if this is the case, there is no way to raise the PSI in your system without a bigger pump. My IFCS is one of the early versions and was thrown together by the installers...even though it has some deficiencies, I believe that they overdesigned some aspects of the system so that I have more leeway on my PSI. For instance, there are only 2 popups on most of my zones...except for ones with the steps.
Your system sounds to me like it is “just” operating at 14psi (max pressure of filter). If it continues to work for you, that actually is the most energy efficient spot for its operation. However the two issues you will have to keep an eye on are (1) the “throw” of your popups (are they actually sweeping and “cleaning” your pool floor and walls to your satisfaction) and (2) as your popups “wear” just a little bit, do they stop rotating? There may not be enough pressure in your system to make these “slightly worn” popups operate correctly.
If I were you, I would give it a go and see how it works out.
