I just finished replumbing my system. I have a new Hayward VSP2302 with a Apollo VA-52 DE filter. During the refit, I replaced 3 elbows with straight runs and the remaining 3 elbows with sweeps. I have a Flowvis flow meter on the system.
So my question: if I dial the RPMs on the pump down to about 1000 rpm or so, the PSI on the filter drops to 0. I know I'm getting flow - the meter shows 20 GPM and I can feel it in the nozzles. Is there a minimum flow needed for effective filtration, or is this just showing me that I'm getting flow with minimal resistance and all's well?
