I got an Intelliflo VSF installed yesterday (I haven't updated my signature line because I forgot to write down the model number this morning).
The pump has a digital readout of RPM, Watts, GPM, and PSI. I recorded some values this morning:
Those are the values reported on the pump's lcd screen when I manually change the rpm (except the last column, which is the DE filter's gauge).
I am disappointed. I bought the VSP based on many users reporting positive outcomes running at whisper-quiet 1000rpm. For me, 1000rpm will take 35 hours to turn over a small pool, and will give no flow at all through the hottub (the hottub has a spillway into the pool, and thus requires more pressure to push water up and over the spillway).
To get any reasonable flow requires around 2500rpm, which is nearly as loud (perhaps louder) than my old Jandy 2HP pump. And the power savings are smaller than I expected, due to the high RPM required.
I'm guessing that my pump's digital readout is accurate and that my plumbing must have "high head," but I don't understand the practical steps of how to find the biggest problems and fix them. Pipes appear to be 2". I have pretty standard equipment, perhaps more right angles than strictly necessary. All equipment is at an elevation about 4 feet below water line.
What is the best way to diagnose the problem? Are there solutions that don't involve massive replumbling of the whole setup?
Thank you -

RPM | Watts | GPM | PSI | PSI on DE Filter Gauge |
1000 | 62 | 7 | 3 | 6 |
1600 | 190 | 12 | 8 | 12 |
2000 | 364 | 18 | 13 | 17 |
