Our spa is pretty far from our equipment, so we have a spa blower that sits on top of a pipe -- it looks like the current Polaris QT blower, 240V 2A, plastic case.
Back in 2007 or so, pool water backed up into it (yikes), so the maintenance guy elevated it, but it's never worked properly since -- shuts off after just a couple of minutes. To fix that, he drilled some air holes in the pipe directly underneath the blower (presumably to relieve pressure) and that let it run longer between shutoffs, but it still doesn't make it past 15 minutes. I recall it going the full 30 before the water backup issue.
So I'd like to replace it. AS I said, I found the Polaris QT blower but there are also metal Zodiac blowers that cost $60 less, along with a bunch of other brands.
Should I replace it with another QT, or are the metal ones more rugged? Which is quieter (don't want to annoy the neighbors), and are all the connections compatible?
Any advice or recommendations for something I can swap out myself would be most welcome. (I can safely handle the wiring.)
