I started hearing an odd, pulsing sound from our Aqua-hot when a particular zone would come on.
Then, the noise became a LOT louder and constant.
I verified that it was the zone which supplied the Bedroom and Baths.
So, the research began. I determined it was a bad circulator pump and have since then learned those failed frequently.
Newell is replacing them with OASIS units now, yet Aqua-Hot sells Buehler pumps. I've got the Buehler kit on order since is nearly half the price.
The badder news is...a couple days ago, I found water under the coach and discovered a pool of water in my wet bay. Sooooo, I'm really hoping the two are related; in other words, I'm hoping the bad pump is leaking.
However, the leak has subsided so I'm wondering if, one, the fluid has dropped below the point of leaking or, two, I have a leak elsewhere and the reason for the noisy pump is CAVITATION and not bearing failure.
Anybody? Chime in...PLEASE!!
