Well folks I ended up here looking for answers. We own a major plumbing company in Texas. We have been in business for 40 plus years. From football stadiums to fixing faucet drips. We do it all. Just for the record we used dura pex tubing for a period of time and 3 - 4 years later it is coming back to haunt us. Splits along the tubing just like the ones in the pictures in previous post. It has been a total nightmare. From leaks in the slabs to ceiling leaks and major damage all over the place. It is all the same dura pex made by nibco before 2006. The tubing was flawed from the very beginning. It is unfortunate for the hard working plumbers out there besides us and the homeowners etc.. that have to go through this. We plumbed numerous very large apartment complexes with dura pex. We have spent 40 years as a credible and reliable company and suddenly something like this raises questions to our customers. And who can blame them ?
I found some good info here and hopefully it will help in our decision in which road we will take to resolve this problem. We purchased it from Moore supply, the major national plumbing supply, and they are helping greatly with the cost etc.... Afterall they sold it to us.
I hope this helps. I realize most of the post are dated back a bit. The more info the better.
