    Pump sizing for the spa

    So, to summarize - which IntelliFlo? VF seems expensive. Granted, flow control is cool, but is it really worth that much? i1 looks like a "restricted" edition of VS, to satisfy California and Arizona compliance rules. No go. VS and XF look the same to the naked eye, feature wise, except that...

    Pump sizing for the spa

    check Indeed, it rains pretty hard here, but there are two things that bother me as far as wet factor is concerned - one, there is a pool pump with 1HP motor that worked for 10+ years without skipping a beat, less than 10ft away, and two, if I remember it right, bearings were dying before the...

    Pump sizing for the spa

    Doesn't look like it. Drain goes to the skimmer, where a divider is used to control which part of water gets from the top and which from the bottom. I don't know what the pad is, so can't answer this question. Unfortunately, replacing any plumbing is out of question at this moment - previous...

    Pump sizing for the spa

    /me sigh... Live, learn, die stupid :) Looked almost identical to me. Granted, I didn't think of finding performance curves for the current motor. ...especially coupled with the fact that it needs to run all year with ambient temperature ranges 32F-70F in the winter and 90F-120F in the summer...

    Pump sizing for the spa

    The idea was to run the pump on low speed for filtering (especially given the fact that filters are more effective at lower flow rates) and switch it on to high only when jets are needed. Yep, "up to" $200. 11018 is about $150 more expensive than 340043, so it's worth it. Somewhere between...

    Pump sizing for the spa

    In other words, running 340043 at low speed will suffice for filtering? Filter: Sta-Rite Posi-Flo II PTM100 Pump: Ultra-Flow of unknown model, the only marking I see is "Label #988719400" Motor: Emerson K63CXESE-4792, but there were other manufacturers' motors dying with exactly the same...

    Pump sizing for the spa

    Existing 1.5 HP motor kept dying about once a year (bearings every time), I've finally lost it and decided to replace it. The question is, was the pump sized correctly? Here's what I have so far: - Spa size is somewhere between 1100 and 1500 gallons; - Head is about 60ft, if I'm getting it...
