Everything the OP needs to know is in that post. Have the test done...and if it holds pressure, I agree that you have no problem.

The OP's original post was on 03-28-2008. Carl's post, which you quoted, was on 04-02-2008. I would sincerely hope that some conclusion has been arrived at since then........

How do you guys do that? I get to reading away thinking, "boy these guys are hot on the trail of a solution to a real or perceived problem" as in this case, only to find out the whole thing started years ago.......
