What do you connect CPVC with?

Unlike green pipe (PPR) and metal pipes, which require heat and flame to weld joints together, FlowGuard® CPVC pipe and fittings use a process called solvent cement welding.

How do I connect CPVC to coupling?





Apply the CPVC cement evenly to the same surfaces, applying sparingly inside the fitting. Working quickly, align the pipe and fitting. Push in and twist the fitting back and forth to evenly distribute the cement and ensure a snug fit. Make sure the marks you made are aligned.

Can you melt CPVC pipe?

Other plastics, such as CPVC, do not crystallize and thus do not have a melting temperature. These are known as amorphous materials. As amorphous materials such as CPVC heat up, they never actually melt.

What makes CPVC pipe brittle?

Exposure of the pipes to certain chemicals cause the CPVC to soften. When this happens, the molecules are no longer locked in place and they start to disentangle from each other causing the pipes to become brittle.

Can I use PVC glue on CPVC?

A: yes. The solvent cement will work on the piping. We recommend the use of the correct Weld-On primer and PVC solvent cement for the particular application.

What is the best glue for CPVC?





Oatey® CPVC Medium Bodied Fast Set Orange Cement is recommended for cold water systems and hot water systems up to 200°F / 93°C. It is approved for Corzan® CPVC piping systems. Its medium body has excellent gap filling properties and is easy to apply.

Why do plumbers hate CPVC?

CPVC will expand when heated, and if the system is installed that does not allow the hot-water lines to freely move when expanded, this can cause a joint to fail,” he says.

What causes pinhole leak in CPVC pipe?

PVC pipe doesn’t just “wear out.” The water inside the pipe may have frozen and expanded, causing the leak. Or something rubbing on the pipe externally wore it thin in a spot. The leak may come from a joint, indicating the joint may have been incorrectly installed.

What is the life expectancy of CPVC?

50 to 75 years



CPVC (chlorinated polyvinyl-chloride) pipes are similar to PVC, but they’re usually a cream color that turns tan over time. You’ll usually see the letters “CPVC” marked on them. CPVC pipes usually last 50 to 75 years.

What is disadvantage of CPVC pipe?

The disadvantages of CPVC include that it is brittle and can’t withstand very high temperatures like copper can. Another disadvantage to CPVC is its high thermal expansion coefficient. Because of this, CPVC may not be the best choice for climates that experience wide variations in temperature.

Can you bury CPVC in concrete?

CPVC fittings are not harmed by direct contact with concrete. Expansion and contraction are not a concern for the pipe and fittings embedded in concrete. Proper design considerations must be incorporated in the portion of the system that is not embedded in concrete.
