The colors can be used to easily distinguish between hot and cold distribution lines. Orange PEX pipe is an oxygen barrier PEX pipe used only for hydronic heating applications.
What is black PEX pipe used for?
PEX pipe is approved for residential and commercial hot and cold water distribution systems, municipal water service lines, radiant panel heating systems, hydronic baseboard heating systems, snow and ice melting systems and building services pipe.
Why is PEX plumbing bad?
PEX plumbing system has been used for more years and therefore its failures has been observed and known. Its major failures is linked to piping and fitting. Piping fails when the pipes are exposed to chlorine that is within the water, exposure to direct sunlight before its installation.
What is orange PEX pipe used for?
Designed for use on hot and cold potable water lines, Orange PEX tubing is commonly used for radiant floor and hydronic heating applications.

What are the disadvantages of PEX?
PEX Plumbing Pipe Disadvantages While PEX has numerous benefits, it should not be used outdoors. PEX is vulnerable to UV rays, which leads to premature degradation and it will not withstand outdoor conditions of extreme cold. PEX is engineered only for indoor use. PEX can’t be recycled.
Should I use PEX A or PEX B?
PEX-A is the most flexible of all PEX tubing types, has little or no coil memory and gives installer an ability to repair kinks with a heat gun. 8 times the OD for PEX-B & C) is helpful, but offers little practical advantage in most cases. PEX-B is a clear winner in terms of price vs. both other types.
Is it OK to use blue PEX for hot water?
PEX without an oxygen barrier is designed primarily for use in potable water plumbing systems. The color of PEX does not change any of the tubing’s ratings. There would be no problem, for example, using blue PEX for hot water lines or red PEX for cold water lines.
What is the safest pipe for drinking water?
Copper pipes with lead-free joint materials are the best choice for water pipes. They are long-lasting and won’t leach chemicals into your drinking water. However, copper pipes are generally more expensive, and copper’s intensive extraction and manufacturing process presents some environmental trade-offs.
Should I replace copper with PEX?
While copper is an excellent material, no material is perfect. You can develop some problems with your copper pipes, and PEX is often a great replacement that can eliminate these problems. Keep hot water hot: PEX keeps the water warmer as it flows through the pipe so that you get hotter water on the other end.
Does PEX plumbing cause cancer?
New pex pipes can leach both toluene and ETBE, volatile organic compounds that are considered carcinogenic. These start at pretty high levels and decrease as the pipe gets older.
What type of PEX can be buried?
Yes. The high density polyethylene (HDPE) material in PEX is durable enough to tolerate being buried in concrete. Most often, PEX tubing is used in radiant heating under tile floors.
Where is PEX not allowed?
It was banned in California before 2010. Since then PEX is allowed to use for plumbing in California. PEX was banned by California’s Building Standards Commission because there was a concern that some chemicals may leak from the pipe into the water.
Can you run PEX under house?
If the piping is on the house side of the insulation, it should be okay. The crimp rings are okay but you need to really also buy the go-no/go tool to verify they are crimped properly. A simpler system is that used by Wirsbo (Uphonor).
