I have a 16x32 in-ground pool: 20k gallons, skimmer and main drain, 1.5 inch black flex pipe and connections, has about 10 right angles in the plumbing, 3/4 Hayward SuperPump-over 15years old.
The pump runs, but will not prime, tried half a dozen times and it has a low volume high pitched swirling sound. it has been acting up lately, especially when trying to use the pool suction vacuum attached to the skimmer. It looses pressure after 5 minutes of cleaning. My last attempt to prime the pump was to use a large shop vac, sucked water from the pump side till water came into the pump basket, turned off the lines to lock in the water, quickly closed the basket lid, opened lines and no still no prime. The skimmer basket is clean, impeller clear.
Funny thing is that i have an old back up pump that someone gave me, attached that and it didn't prime either. Did a little research on that replacement pump, and found out it's for an above ground pool. It doesn't self prime!
So I guess, my trusty and rusty superpump just died on me and i'm racing to find a new pump soon, before my water turns. I've been looking into the 2 speed pumps, to save a little money on electricity. The variable speed pumps seem too pricey, especially since i live in CT and only use the pool for 3-4 months.
Could anyone led me in the right direction?
So far, my research has brought me to the:
Hayward SuperPump SP2607X102S
Pentair SuperFlo SF-N2-3/4A
Whisperflo 3/4hp, 2 speed- has 2 inch connections, is it too powerful for my lines.
Are there anymore that i should consider in that price point? i like to stay under $600, if i can.
Is 3/4hp correct for my size pool?
I'm not a slave to the hayward brand, but from what i've read on this forum, the 2 speed superpump looks like it might be the right fit.
Any help would be appreciated.
