yellowing plastic

[Cgy_Spa]

Hoping that someone can help me out here...........

My spa has been up and running for 9 days now.  One of the air controls, the diverter, and two jets are starting to yellow.  They are gray plastic, and this is on a Hot Spot Sorrento.  Water parameters look ok (test strips)  Is this from the ozone, closing the cover too soon after shocking (I have only shocked once) ??

Any help is appreciated.

I'm going to take a wild guess, but I wouldn't expect any of those possible causes to occur after 9 days. Maube a problem happened in the plastic molding process. Ask your dealer, what he thinks, or one of the HS dealers might come along with a comment soon.

The plastic has not gotten notably worse, but I went in anyway today to talk to my dealer, and have the water tested.

The odd thing is, everything tested good.
Ph 7.6
Calcium 200
TDS 675
Alk 128
Bromine 9ppm  (I had shocked this morning)

He could not think of anything that could be causing the yellow plastic, and said that if it progresses, or bothers me to cal the service manager and he'll replace the components. (The "salesman" I bought the tub from is the General Manager)

OK, that satisfies me, but then I'm in the tub tonight and the wife tells me that her and my daughters white suits are yelowing as well!

Could this be a faulty or over active Ozone?  I really cannot think of anything else, except to drain/refill and throw something white in there afterward........

No one has ever seen anything like this before?

Your post has jogged my memory.  I am expecting delivery of my 06 Geneva next weekend.  It is a wet floor model and when wet testing I thought I noticed one of the gray diverter valves looking a bit yellow as well.  I have no idea the reason although I thought the chlorine probably caused it.  Either way I am curious what repsponses you are given and will call the dealer and ask about it.  I will let you know what she says.

Maybe it's the bromine?  I plan on using dichlor (chlorine) and will ask the dealer what they used.

It's Bromine granuals, not a floater.
Actually, it's 85% dichlor, 15% Bromine  (SpaGuard brand)

I think I'll pick up some 100% Dichlor (routine is the same) and buy a new white suit for a test.........

When I was using bromine, much of the plastic on my spa got a tan colored stain.
It was never there when I was using Baqua- it started appear shortly after we switched to Bromine.  It was pretty easy to scrub off with a scrunge pad and spa surface cleaner.  
 Now that we're using dichlor, the tan staining is gone.  
Maybe you're experiencing the same thing as I did.
