Welcome to our forum.
I have never seen the gurgling occur personally but it is evidently something that needs to be addressed. I spoke with a technician at Watkins and was told that you should contact your dealer and request an air adjustment valve part # 73808. This will control the amount of air introduced into the ozonator.Terminator
When you take the hose off of the generator the gurgle gets even louder. Put the hose back on and it quiets down a little.
You'll always hear something if you listen close enough but it sounds like in your case you don't have to concentrate too hard to hear it and it just needs a little adjusting.
If taking the hose off resulted in less restriction and more noise afollowed by you putting the hose back on and getting noise abatement a bit I do believe putting a metering restrictor on the inlet to the ozonator will allow you to ever so slightly reduce the flow to the ozonator and making it quieter. You'll always hear something if you listen close enough but it sounds like in your case you don't have to concentrate too hard to hear it and it just needs a little adjusting.
Bump for MLG.
Thanks Reese!!! This was quite an interesting thread, and definately sounds (pun intended) like my problem. I wonder if I could put on that valve..... [smiley=undecided.gif]
