Hello,
I have an older Zodiac Polaris 2hp 240v metal spa blower 1-566-03 that bit the dust. It really was over powering for our spa but the kids loved it. It only powers the 4 floor jets in the bottom of our spa not the side jets. I want to exchange it with the 1.5hp 1-516-03 hoping that it doesn't produce as much bubbles. Will this down grade still have enough power to blow bubbles through the floor jets of the spa..that's my only concern. The blower is about 45ft from the spa, 2" pipe, probably two 45deg elbows and guessing a check valve somewhere. Any advice would be appreciated! Thanks!
 
Thanks! If I'm running the calculation properly it looks like I have only 10" of water back flow and any of the blowers 1hp-2hp would work? Looks like I should be good with the 1.5hp blower I hope. Plan on buying it online and returning it would be a nightmare
