Hey all. Thanks for the help in advance. I purchased a house about 1.5 years ago and it came with some pretty old equipment. Has a sand filter that I believe is a Triton TR100 and had old pumps. 2" plumbing. I replaced my old single speed pump with a Hayward Tristar 950 VS with Omni Hub last year and so far love the automation and such I gained. Now, I am trying to work on tuning everything to the speed I need and such. My pool is a decent size at about 30,000+ gallons. ( I filled a set volume and timed it then when filling the pool I multiplied that by time taken to fill) Now here is where I need help. I have always had what I consider pretty high pressure of 30-35 psi on the filter reading depending on what is open and shut and the such. I recently swapped the sand for FilterBalls as well. I put in a flow meter and on highest setting (3450 rpm) I get about 70gpm and on Med (1725) I get about 15-20 gpm. Doesnt that seem really low? Even on high I would have to run my pool about 8 hours just to turn it one time. Also, is it normal that if I bypass the Mastertemp 400 my system pressure lowers about 5 PSI?
