When we bought this house in 1995 - it came with the pool. It's been an adventure, and I've learned alot.
when we bought the house - the master bath had one of those "hydro therapy jet" tubs. A couple years later, when we did some remodeling and rearrainged the bathrooms - we discovered that the pump for the tub was a .75 HP Hayward PowerFlo II (without the strainer). Not knowing anything about it at the time, we kept it anyway as a "just in case".
Fast forward to about 4 years ago.At that time, we were using a Hayward 1.5 HP Superpump, that sat outside over the fall, winter and spring, sometimes with leaves covering / touching it. As you can probably guess - the outside of the motor rusted out / crumbled to dust.
What to do - I remembered we had the PowerFlo, and after checking Hayward's website - which said the PowerFloII is suitable for above ground and SMALL Inground pools - can lift up to 8 feet suction. I figured, WTH - even without the strainer, it should pump ok until we can get a permananent replacement. Plumbed it in, got 120V power to it, and after it was primed with a hose down the output - it did a pretty reasonable job for the 2-3 weeks until the Pentair SuperFlo in my signature came in and was put into service.
Since then, I did get the strainer assembly, and the last couple summers, I've thought about using the smaller pump instead.
The SuperFlo shows about 15-16 PSI on the guage, while the PowerFlo was about 10-11 PSI (as I remember). The waterflow is also "calmer" with the smaller pump, and I have a bit of an issue with real fine dust settling out with the larger pump (I can vacuum the pool and 2hours later the fine dust is like it never was vacuumed at all).
So - the question is - would the smaller pump actually help better with this fine dust issue ? Or do I just need to try it out and see what happens ? The smaller pump does use about 300 watts less power, and both pumps are single speeds. For that matter - is there a better solution for the fine dust (yes, I've thought ALOT about getting a robot cleaner). I would also like to get a heatpump for the pool (I got to 80 degrees from the Middle of July to the 3rd week of august - and yesterday it was at 75), so would the smaller pump be able to keep up with that as well ?
Thank you for your time and consideration.
