We're in the design stages of having a new house built. We're getting conflicting advise on what type of pipe to use. There seems to be positive and negative for all 3 types. If you were building a new house what would you use?
1. PEX - Positives: ease of installation, cost, ability to run each line individually and shut off that line if necessary. Negatives: Not a "soldered/glued" connection, connection can work loose. Is this poly butalane all over again? Given time will PEX stand up over time?
2. Cpvc - Positives - glued connection, connection won't work loose. Cost is relatively cheap. Negatives - increased installation costs, longevity. My current plumber says that when he has gone in to replace a section of Cpvc in homes as new as 2 years old, when he goes to cut the pipe the pipe crumbles in his hand. He said this has happened to him several times.
3. Copper - Positives - soldered connections - long lasting. Negatives - High cost of materials, higher cost of installation, the builders in this area don't have plumbers used to dealing with copper, so not sure how good the installation would be. I've also been told that copper can develop pin hole leaks if water has a high acid content.
So what you would you have installed?
