Charley... ahhh... I dunno why, but I thought you said sommat was wrong with a fitting or coupling or sommat? But, I read back and can't find it??? So, if not, how could a blockage be considered normal wear and tear?

Re the other... fact is, I have a lot of stuff like that. I keep a close eye on all sales and when I see sommat like that on sale, I buy it because it's nice to have when the shops are closed, you don't have to go to several shops looking for what you need, you don't have to overpay. Even the moisture meter... a good one will run $2-300, but it can easily save thousands. And, it comes in handy when you have a bad back and need your lawn mowed by the neighbour you helped out by pinpointing his foundation leak so he didn't have to tear out any more of the wall than necessary.
