My wife and I are currently on the tail end of our live in flip. All things considered, things have been pretty smooth but one mistake was very costly in time AND money. I represented us as our agent in the deal and should have know that these tract style homes built in the 90's have a high probability of polybutylene plumbing. We did the typical inspection, which turned up nothing as the stubs were all copper. The seller filled out the disclosure stating they were unaware of what type of plumbing it was. Being an agent, I always have these types of things in mind for my clients and inform them about PB plumbing and similar issues whenever in neighborhoods known to have used PB. With everything going on, it just slipped my mind and I didn't look into it any further as there were already so many other repairs we were thinking about. After investigating what we thought was a small roof leak ended up being a pipe leak and BAM, there was the big, ugly grey piping staring me in the face. So roughly $8,000 to replumb the entire house and have all the drywall and paint fixed (after we were already done with drywall and paint) plus right in the middle of COVID, pushed us weeks back on a lot of the progress we were making. Insult to injury, nothing will kill your budget more than not having a kitchen, and having to eat out for almost every meal.
Needless to say, I will always be digging through attic insulation to try and find what kind of piping was used in the future lol.
