Hi everyone. First post. I have been reading up and followed and learned a lot. Just purchased a house with a 10k pebbletec pool and the Jandy Stealth promptly died. We had other issues prior to that which I have resolved but nothing major. I have disassembled the Jandy DEL60 DE filter and cleaned that out just before the Stealth died miserably - it's about 12 years old so I'm not surprised.
So after replacing with an intelliflo 2 VST I have a few questions. I'm going to try and use the intelliflo GPM calculator by MAS. I think that will help me set my RPM for at least one turnover of the water - I know the new Intelliflo is slightly more efficient but it will give me a good starting point and I can go down from there I assume.
1) My psi on the DE filter was always around 8 psi but now after install the PB had the high/skimmer setting at 2750rpm which has the pressure up past 20psi on the filter gauge. Is this an issue? It then looks like it is "dirty" but I know it isn't because it was cleaned a couple weeks ago from top to bottom and then recharged with DE by weight (literally got a scale out). Should I just not worry about the psi being higher when it is running in that higher speed?
2) The paramount in ground system was serviced (replaced module inside) prior to purchasing the house because the popups weren't working but the gauge has always read 10psi or less. In the manual I have for that system it says 14psi is the reading it needs to show. I think it is off because the water is coming out of the in floor cleaners at a very forceful pressure at the 2750 rpm on the intelliflo. Should I be concerned about the reading on the gauge? It doesn't seem to go over 10psi. Get a new gauge? Everything cycles correctly it seems.
I know that the minimum I'll probably run the pump is around the 800-1000rpm range which as I have researched seems to be where the efficiency is worth it without going so low to not be worth the trade off. At this rate the DE filter gauge doesn't read anything above a few psi and the paramount although cycling doesn't show much as far as psi as well.
3) Also I have a waterfall that has some funky chips/cracks/chunks down to the rebar. It also appears to be leaking through the concrete. I'm thinking someone will have to be called to repair it but I'd like to get everyone's opinion on this. I don't think it is something I want to tackle myself.

Ok thanks for any info and help. This forum has been super helpful in learning about pools.
