CPVC pipes can withstand hot water temperatures up to 180 degrees F.

Why is CPVC bad?

Pipes made of CPVC are more likely to break in freezing temperatures than those made of other materials. Direct exposure to ultraviolet rays from sunlight can cause CPVC materials to degrade. CPVC produces toxic fumes when burned and can present serious risks in house fires.

Should I use PVC or CPVC?

We recommend the use of PVC for recreational use/building, cold water systems, vent systems, and drainage systems. CPVC is recommended for applications where the maximum temperature will exceed 140 degrees Fahrenheit, but stay under CPVC's max rating of 200 degrees Fahrenheit.

What kind of glue do you use on CPVC pipe?

The Oatey 8 oz. CPVC Cement is formulated to bond CPVC pipe and fittings in water-distribution systems. The solvent cement softens the surface of pipe and fittings to create a strong bond.

Can Schedule 80 CPVC be threaded?

Only Schedule 80 PVC pipe can be threaded. Schedule 40, Schedule 80 CPVC or SDR pipe cannot be threaded; molded threaded adapters must be used on those systems. The pressure rating of molded or cut threads must be derated by an additional 50% beyond the pressure rating for pipe and fittings.

What are the disadvantages of CPVC pipe?

Cons of CPVC Pipe CPVC can't withstand extremely high temperatures like copper pipe can. CPVC is not suitable for climates with extreme temperature variations due to its high thermal expansion coefficient. CPVC is more expensive than many other piping options.

Is CPVC illegal?

CPVC has been a nationally accepted material since 1982, but California has only permitted its use on a limited basis since 2001. ...

It breaks down the surface of the pipe it is applied to and chemically bonds pipes and fittings together. For this reason, you cannot use just any PVC cement to join these two materials together. CPVC, as we explained earlier, is a stronger version of PVC pipe with a higher melting point and tougher chemical structure.

What's the difference between PVC pipe and copper pipe?

CPVC is the same o.d. as copper, but since the wall is thicker, 1/2" CPVC is MUCH smaller than 1/2" copper. PVC is sch. 40 so its o.d. is the same as steel pipe but its i.d. is also smaller than steel pipe.
