For example, Uponor offers ProPEX fittings and valves that directly connect the PEX pipe right to the water meter.

Is CTS pipe the same as PEX?

Notes: PEX tubing sizes are denoted by CTS (copper tubing size), not OD (Outside Diameter) or ID (Inside Diameter). OD of PEX, copper and CPVC pipe with the same size (CTS) is the same. This is why push fittings can be used with all of these pipes.

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.

Is PEX pipe better than copper?

Copper Pipe Lifespan. PEX pipe is not only cheaper than copper but more durable too. PEX is immune to corrosion and mineral build-up, and it’s not affected by electrolysis, which can cause small pinhole leaks in copper piping. PEX pipe is more resistant to bursting in freezing conditions than metal piping.
