Hey all,
Last summer I completed my Owner build of a 900 sq ft free form pool. I have 4 IntelliFlo XFs and my main filtration one has given me issues with flow since day one. At 3400 RPM in pool mode, I can’t get north of 70 GPM no matter what I try.
Main pump services pool and spa. Pool side, there is a 3” main drain suction, and 2x 2” skimmer lines. On the return side, every return is individually plumbed - so that’s 8x 1.5” returns and 4x 2”.
In addition to IntelliFlo, I have a Quad DE 100 filter with no multi port valve, propane heater and heat pump.
In normal operation, with bare minimum flow going through heaters to trigger them, I’m at around 55-60 GPM at 3400 rpm with a clean filter. 48-50 GPM at 2800 rpm.
I have tried completely blocking off the heaters and removing the filter cartridges and internals, and I still cannot exceed 70-72 GPM at full speed. Based on pump curve I fully expected well over 100 GPM and designed my infloor off of 90.
My spa booster pump achieves 95 gpm at the top end, and I think that’s more jet limited than anything (12 jets on that).
Any thoughts? It really makes my in floor completely useless.
