Hi all:
I have a Sundance hot tub. Over the last month, I noticed that the hot water return jet is jetting out a lot of tiny air bubbles. It never used to do that before.
I changed water and the filters today and it still does the same thing.
Do I have a problem? Is it a chemical thing? or do I have a leak? Is air getting into the plumbing/pipes for the water heating system?
Thanks you so much in advance!
Paul
