Lurch,

Bt the way, you should have started a new tread, not bust into a (not off
topic) tread about plumbing !

Eh?

Well yes, I was a little surprised by that comment, too. I thought I had
started a totally new thread, and my newsreader (Outlook Express) gives
every impression of agreeing with me.

But if I didn't, then as I said, my apologies.
