I've been using a Kreepy Krawly for the several years. It does a decent job but it tends to get stuck in corners way too often. It also tends to stay towards the deep end and not so much in the shallows.
I'm having to do one of two things:
1. Either replace my entire filter pump, or
2. Replace the motor on the filter pump
I, presently, have WFE-3 Pentair Whisperflo (3/4 HP) that I need to repair/replace since it recently stopped working.
I've read the section on pump sizing and I realize that using an automatic pool vacuuming device (like the Kreepy) creates significant additional resistant on your pool's filtration demands. I can understand why the mfgs don't discuss this issue much since most homeowners would not be thrilled about having to spend several hundred dollars (or thousand) in filtration upgrade just to use their product...
Question #1: If I went up to 1 HP (vs the current 3/4HP pump used), would that allow for greater suction by the Kreepy and, subsequently, keep it from getting hung up in tight corners so often?
Question #2: How can I calculate for the additional resistance created by the Kreepy? Is there a general run of thumb, ie. plus 1/4 HP or 1/2 HP when using this type of equipment. I'm using close to 30' of hose, alone!
Question #3: Can you mount a 1 hp Whisperflo motor on a WFE-3 Whisperflo Filter pump? What is the specific specification that determines if I can or cannot?
Thanks for your help!
