Hi all. I just installed this FlowVis in preparation for a TriStar VS900 variable speed pump being installed in the next few days.
My system is currently a Tristar non VS and it shows 1 HP and 1.85 HP (I think maybe it says SF here as well - service factor, whatever that means). I have a sand filter (S244T), 9 techno solis solar panels on the roof. The line from the skimmer is 2" and everything after the pump is 1.5"
Currently, with the solar off, the flow rate is about 55gpm and with the solar on, it's about 45gpm. The pressure gauge on the sand filter shows 21psi with solar off and 27psi with solar on.
I 'think' the 45gpm is good with the solar on, but I've always (since day 1 - in fact I think I might have posted a few years ago wondering if my pump was too powerful or my filter too small) wondered if the flow was too great for the filter. If I'm understanding the s244T manual correctly, the maximum flow rate for 1.5" pipe should be 45GPM.
What do you all think is a good flow rate to aim for with the VS900 when it gets installed? Opinion for solar on and solar off would be appreciated.
Thanks.
