A piece of "Thompson FlowGuard Gold CPVC 4120 SDR 11 Potable Water" pipe developed a pinhole leak in an interior wall. When the sheetrock showed obvious signs of water damage I removed the sheetrock and exposed the leak. The licensed plumber I had in to repair the leak - he replaced the section with copper - said that the pipe is brittle like potato chips and crushed an end to show me how it shatters. The professional plumber version of the listserv has a posting by "ProTech" out of FL complaining about this "defective" pipe:
"Default Defective FlowGuard Gold cpvc pipe
I've been getting a lot of leak calls on clvc lately where the pipe splits down the center no where near a fitting. I decided to cross section the pipe and found extrusion defects on the inside wall of the pipe. The defects are little valleys that run the whole length of the pipe.

So why has this not resulted in law suits?

Pictures and video to follow."

Our house was built in 1997 by a large homebuilder Centex (now absorbed into another builder) in a mass tract building project (143 homes, Castle Chase subdivision in McDowell Mountain Ranch in Scottsdale, AZ. The plumber named 3 other nearby subdivisions by that builder that uses FlowGuard Gold plumbing pipe. The fact that this house was built as part of a mass-built tract would discount any claim by the manufacturer of FlowGuard that the pipe must have sat out in the sun and deteriorated. Would welcome getting in touch with others who have had problems with this pipe.
Thanks,
Craig

You could always start one. See if you can find the law firm that sued the polybutylene pipe manufactures.

I have heard from plumbers that they are noticing CPVC pipe becoming brittle especially on the hot water lines.

My Flowguard Gold 1/2 inch pipe broke at the cut off valve last week. It was behind a laundry tub and very hard to get to. Should have had nothing to cause it to fail. Very concerned about the rest of the house as it was used everywhere.

One more reason to repipe with PEX. CPVC will get brittle with age and won't cut. It just shatters if you don't round the cutter on the perimeter, sort of like cutting copper.

Our FlowGuard pipe sprung a tiny spray leak within a wall behind the shower head. Soaked the wall and had to break in and get plumber to replace section of defective pipe. Home built in 1997 in Scottsdale, AZ. I too am concerned about how much pipe we have within the walls and what a disaster it would be to have similar leaks. My understanding is that there are a lot of homes that were built with FlowGuard pipe that have had such problems. I saved the piece of the defective pipe that developed a spray leak. Would like to compare notes with people with similar issues and see if we can get pipe manufacturer to replace defective pipe.

I'm with you. My house was built in 1996. I am outside Atlanta. The problem occurred in the basement garage. It isn't that cold there. My entire house is plumbed with it. I am so frightened my upper floor will spring a leak and I won't know it until it hits the first floor or the basement. I can't go thru $1,000 deductibles each time with all the possibilities. Let me know if I can help in anyway. I have extra piping here, with the 1996 date on it.

Hi, I'll keep your contact info. I wonder if there is any possibility of a class-action lawsuit on this? Replacing the in-wall pipe would be incredibly expensive. We don't have basements here in AZ, so that's not an issue. The carpet got soaked, but we're just about to replace flooring, and will use porcelain wood-look tile that wouldn't be ruined by moisture, like wood flooring would. Let me know if you hear anything and I'll do the same.
Thanks, Craig Hutton

Sorry, this site can't be part of any under taking of any law suit.
