I recently picked up a Doheny house brand 1.5hp pump. The existing filter is a Hayward 210T and from what I can tell has a designed flow rate of 44 GPM. The pump is apparently 83 GPM (dumb I know, wasn't even thinking about it).
There is some, but not a lot, of sand settling onto the backwash discharge (about 10" at most out). The pool, which I'm now cleaning up, has gone from green to brown but has some leaves at the bottom form winter.
Wondering if I mis-ordered? The PowerFLo Matrix that this pump replaced also had a similar GPM in the 80s or so. Even the lowest 3/4 Doheny has a 62 GPM rating so just trying to figure it out.
Is this (sand during fist couple of backwashes) normal or did I really mess this one up?
