Ah, don't be to glad. An Aquahot is no panacea either. I had one in my previous LXi. Lots of problems keeping them running also. The Hurricane is very similar to an Aquahot. Actually, The Hurricane is performing flawlessly, It's the distribution system that BB put in the coach that's the problem.

I also agree about flushing and direction. Hey, what if you close zone 1 and force all through zone 2.......easy enough to try without too much work, no?????????? This way the circulation pump it dedicated to zone 2 only to force the air out, if there is any???????

Pete,
In the pic I posted, you will see a yellow handled manual valve on the supply lines after a tee. that valve shuts off the front zone that is working properly. BB had to install that tee to reduce the flow to the smaller front circuit so that more fluid would would be routed to zone 2 which is a much longer loop with more registers. Closing that valve completely does dedicate the pumped fluid only to zone 2. I've tried that to no avail. George said that valve should remain in the half closed position to properly balance the circuits
