Did a full forum search for in-floor cleaner advice and it appears that most members would not install an in-floor cleaning system. Of course, I didn't find this website until AFTER I built my pool in Apr 2013! However, I really like the convenience of the system and, so far, it has kept my pool nicely clean with minimal effort (just a twice weekly brush and skim) from me. Since the pool is only 1 year old, I am still learning the finer points of my system. Like most folks, I want to run the system in the most efficient manner and take full advantage of the VS pump, etc..
My in-floor system is an A&A 6 zone system with 3 pop-ups per zone. My pump is a 3hp Pentair VS 3050. The pop-ups are A&A Gamma 4 venturi powered cleaning heads and my pool depth runs from 3.5' to 5.5'. I currently run the pump at 2800 rpm (max rpm is 3450) while in the cleaning cycle–which gives me about 25 psi measured at the top of the filter canister. (The skimmer and wall returns are on a separate line and run only in the filtration cycle when the in-floor cleaner is off.) I also have an EcoSkim venturi-powered skimming system that allows me to draw full suction through the main drain and still keep the skimmer operating.
My questions are:
1. What is the minimum pressure (at the filter canister) I should look for to run the pop-ups effectively? (The current "flow rate" is about 50 GPM read at the return to the floor cleaner manifold. Unfortunately, there is no pressure gauge at the return to the cleaner manifold.)
2. What nominal pressure should I look for during my filtration cycle? (Currently I run the filtration cycle pump at 1800 rpm which yields about 5-6 psi measured at the top of the filter canister.)
3. How often should I check the gearing in the cleaner manifold for wear?
Thanks in advance! BTW, I have completely embraced the TFPC chemistry recommendations and now have a sparkling clear pool at minimum cost!
