Thanks for the responses guys, I am definitely going to use this to try and get a few grand knocked off our agreed upon price. Luckily the extent of the PB is only the 2 upstairs bathrooms and I've done quite a bit of copper myself so I think I'll just replace with copper - though I'm looking at PEX also. I just hope PEX doesn't become another PB in 10 years...
FWIW, this place does have the crimp type connections, but with the metal fittings, which I'm told are better. It's been leak free for 18 years and it looks like I'm going to replace it right away just for peace of mind so hopefully it holds our for a few more months.
On a related note, anyone have one of
these ? I'm thinking of putting one in for insurance, PB pipe or not. My wife and I are both away from home for long periods and the thought of a burst pipe flowing uninterrupted gives me chills...
