All I can tell you at this point is to keep on them, for everything, it sounds like the service company is trying though..
I'm going to try to be an optimist; the spa just ran its morning one hour filter cycle - which for the past two weeks consistently resulted in the sound discussed previously - and today the sound was quite normal. Maybe it was related to the Ozonator/plastic plug after all?
Just curious, are those of you who are dealers aware of the plastic plug that needs to be removed from the jet that the Ozonator is connected to?
So far, I feel like my dealer dropped the ball on three things:
1) After I explained that this was my first time owning a spa or pool and that I knew absolutely nothing about chemical strategy, they did not tell me what now seems to be simple and obvious; never add chemicals when the water is not circulating.
2) They did not ensure the valve for the waterfall feature was properly installed from the factory. The first time I turned the valve 1/4 turn it blew out, resulting in a powerful geyser spraying my brand new tongue-and-groove ceiling until I could scramble to the control panel to turn-off the pump.
3) They did not know to remove the plastic restrictor in the jet after connecting a dealer installed Ozonator.
