Thanks Paladin for the info. I don't know how my thread title got changed.
The tube in question is not WE, tho it's not far off in price. Just out of warranty @13 months. I know for about seven months they only had 10-12 hours/week at most. To be honest, after sending the pair of tubes back to the mfr, I kinda thought they would make good on it. I think pride of product would warrant a one month grace. Especially on flat vacuum. But no. Even more confusing was the five months the tubes sat in their back room until I decided to rattle their cage and find out what was going on.
Thanks again
