First time here looking for confirmation of my research or a different opinion. I've read the Hydraulics 101 post (which, by the way, is outstanding) and gone through all the calculations on the detailed spreadsheet. It comes up with TDH=56 and GPM=63. For 19k pool and 6hr turn I need at least 53gpm. Where I'm stuck is on velocity. Guidelines indicate a maximum flow rate rate of 38gpm on suction side at 6fps. If the target flow rate is supposed to be between the turnover minimum and the velocity maximum, then the math doesn't work. The plumbing is 1.5", which I suspect could be the issue. I hope not. What am I missing here? It ran for 2 months last fall after being installed and didn't blow up. Maybe I've been at it too long now and my brain is fried. This all started because I want to install a heat pump and I wanted to make sure the flow rate was compatible.
On secondary note, it also seems the filter is too small based on the guidelines. The S220T has 2.6sf of effective filter vs. at least 3.6sf recommended for my size pool.
Forgive me I've just overlooked something obvious. New Pool Owner.
Thanks
