You'll have to get a blue magic marker and color the entire cold line or the pex police will come and ticket you for code violation. **Joking!**Devil5052 wrote:I just bought 100 ft of 1/2" PEX Red tubing for $24.95 at Lowes. I want to run a short line for hot water to a sink & the rest for cold water runs to new sillcocks I will be installing. The red should be fine for both applications, right?
I believe the only reason for different colors is for future conveinience. If you tap into a line to add a fixture you'll know if it's hot or cold by color. They are the same pipe regardless of color. I do know some states now require all pipes to have decals on them telling what they are. Maybe the color coded ones don't need decals. I do not know if any plumbers are actually inforcing it, but Maine the law now says if any licensed plumber or heat person does any work in your house he is required to tell you of the law and insist you pay him to decal all pipes. Crazy!
