Thanks Tom.

The O rings are only a few years old at most. Sounds like either my install of an O ring was flawed at time of new tank install, or recent removal and re installation of the metal vent pipe, w/o replacing that O ring, was the wrong thing to do.

It just seemed unusual that it would leak now given I've put quite a few miles on since vent pipe work.

Neil.
