A neighbor lady called me in a panic with a busted water pipe. I found that some 20 years ago, her husband (recently deceased) ran about 150' of 1" PVC to reroute the supply line from the original service entrance at one end of the house, around to the garage at the other end, where he was installing a water softener.
Twenty years later, this PVC is so brittle at the joints that a hard look will break it. The way the joints were breaking as I dug up a section to repair it, I've gotta think that it's a giant failure waiting to happen. Is PVC approved for an installation like this? Or does this need to be copper (this is in California)?
Follow-up question -- Is the jury still out on PEX (and PEX-related products)? With 20 years of landscaping in the way, it will be difficult to run a new line along the route of the existing, and it would be an even bigger PITA to try to route and sweat 100' of copper through the low attic of this rambling ranch house (thus the circumnavigation with the PVC). But she's having the place reroofed soon, and while the shingles are stripped off, it would be a snap to reach into the attic from outside and run PEX from one end to the other.
