My gauges are old. I don't want blather. I want facts. And references.

I always search first, so, I already did my search and posted the results.
But maybe someone else out there is a better searcher than I am and can
provide a reference. Surely I'm not the best there is.

I did follow up on the suggestion to call Coke (even though I'm using
Trader Joe's bottles).

The Coke plastic PETE bottles (from 20 oz to 2 liters) are either tested to
150 psi or to 250 psi (I'm waiting for them to confirm by mail which ones).

It would be nice to have more references though as I can't be the best
Internest searchist out there....

Coke bottles used for water heater expansion tank

I would be leary about the ability to withstand 150 or 120 PSI being
valid at the highest temperature that can be encountered in this
application. I have had experience with boiling water causing PET soda
bottles to soften and go out of shape without any significant pressure at
all.
