plastic water supply lines


Hi, I understand that in some Cities have approved a non copper water supply lines. Made of a flexible plastic, non toxic tubes. Any information on this product and is it on its way for national approval. I heard it does not sweat, holds the heat but will it get brittle after years?
Thanks

There are multiple alternatives to copper and cast iron.
There are PEX colored flexible plastic lines and CPVC off-white rigid plastic for hot and cold water supply lines, PVC rigid white plastic for cold water supply and primarily drain lines, and ABS black plastic rigid for drain lines.
Always check with your local Building Inspection Department for local codes. You have to anyway for permits and inspections.
Good Luck!
Mike

Mike's right. PEX (Zurn, Wirsbo, etc) and CPVC (such as FlowGuard Gold) are the two common plastic supply lines. Both are excellent products, and I think the benefits definately outweigh the minimal potential problems (neither will get brittle unless you try to cook them).

Some cities don't allow them. Typically, it is because of a building official that can't let go of the past and by accepting innovative products.

That's what they said about polybutylene. I don't really have a choice and install a lot of pex. When it comes to my house though I stick with the tried and true copper.

PEX has been on the market a long time. Polybutylene instantly proved itself to be a poor product.

Both PEX and CPVC are widely accepted. They are both good products, as is copper. In fact, if you are on a well, copper may not be a good choice at all. There are some things you need to know about using either PEX or CPVC but it's not rocket science and, once you take the time to learn how, it's pretty simple to install a water supply system using either product.
