Is CPVC the same size as PVC?

Is CPVC the same size as PVC? No. CPVC is measured by O.D., which makes its sizing similar to hard copper. PVC is measured by I.D., which makes its sizing similar to iron pipe.

Are PVC and CPVC fittings interchangeable? 80 PVC and sch. 80 CPVC will fit together because they have the same ID and OD. The same is true of schedule 40 PVC and CPVC, but that type of CPVC is rarely used. One major difference between these two types of piping, when it comes to sizing, is the fact that CPVC is made in two different sizing systems: NPS and CTS.

How do you tell the difference between PVC and CPVC? They both are strong and rigid forms of pipe, and they can be found in the same pipe and fitting sizes. The only real visible difference may be in their color – PVC is generally white while CPVC comes in a cream color.

What sizes does CPVC pipe come in? Industrial CPVC pipe is manufactured by extrusion in sizes from ¼” to 12″ diameter to Sch 40, Sch 80, and SDR (Standard Dimension Ratio) dimensions. CPVC pipe for plumbing systems is manufactured by extrusion in sizes ¼” through 2″ copper tube size (CTS) dimensions.

What happens if I use PVC glue on CPVC?

When working with CPVC piping, use multipurpose PVC/CPVC glue or a CPVC glue; glue made specifically for PVC will not hold properly on CPVC and could lead to leaks or breakage. CPVC pipes can withstand hot water temperatures up to 180 degrees F.

Why is CPVC bad?

“Over a period of time, it gets brittle and cracks and breaks and the glue joints continue to deteriorate through the pipe and go bad,” Rainaldi said. Plumbers said Florida’s heat and chlorine in the water is also bad for CPVC pipes. “With CPVC, this is a very common thing.

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.

Can you use CPVC for water lines?

CPVC tubing is ideal for water supply lines. It’s easy to cut and assemble, using compression of cemented fittings. It’s durable too. Harsh water won’t harm the material, unlike copper, which will erode from acidic water.

Why is CPVC used for drinking water?

Thus, CPVC Pipes ensure safe potable water for communities across the world. The reason why FlowGuard® Plus CPVC pipes are the safest pipes for drinking water is that the materials that are used in the creation of CPVC prevent biofilm formation on the pipes.

Are there different types of CPVC?

ASTM has established a number of standards to verify the long-term performance of CPVC pipe, fittings and solvent cements. Following are three of the many standards Corzan CPVC satisfies: ASTM F441: Standard Specification for Chlorinated Poly (Vinyl Chloride) (CPVC) Plastic Pipe, Schedules 40 & 80.

Do you need primer with CPVC glue?

Primer is needed to prepare the bonding area for the addition of cement and subsequent assembly. Use a proper applicator, such as a dauber, swab or paintbrush, approximately half the size of the pipe diameter. Apply the primer to the inside of the fitting socket and to the outiside of the pipe end.

What does CPVC stand for?

CPVC (chlorinated poly (vinyl chloride) is a strong and rigid thermoplastic material that is used for hot and cold potable water applications in residential construction. Because of its makeup, CPVC is immune to damage from highly chlorinated domestic water and has a higher temperature tolerance than PVC.

Can you mix Schedule 40 and 80 PVC?

As mentioned earlier, both schedule 80 and schedule 40 PVC pipe have the exact same outside diameter. This means schedule 40 and 80 pipe do fit together and can be used together if necessary.

What kind of glue do you use on CPVC pipe?

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.

What color is CPVC glue?

CPVC cement is either yellow or orange, depending on the brand of pipe.

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.

What is the life expectancy of CPVC?

According to the experts at the International Association of Certified Home Inspectors (InterNACHI), CPVC pipes are expected to last for 50 to 75 years under optimal conditions.

Is CPVC illegal?

The new regulations approve CPVC pipe for use in residential water supply piping systems. CPVC has been a nationally accepted material since 1982, but California has only permitted its use on a limited basis since 2001. The commission’s vote was unanimous and CPVC will be placed in the 2007 California Plumbing Code.

Why is PEX better than CPVC?

CPVC Pipes Offer Better Water Pressure Than PEX

With PEX, the pipe fits around the outside of the fitting so the internal diameter of the pipe is reduced at each fitting—even when “full flow” expansion fittings are used. Depending on the fitting used, this can reduce the internal diameter of a ½” pipe by 21% to 35%.

What causes CPVC pipe to brittle?

When CPVC pipes are first manufactured they are highly ductile. 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.

Does CPVC get brittle with age?

Will CPVC fail because it gets brittle? When properly installed and handled, CPVC will not spontaneously fail due to brittleness. As CPVC ages, it becomes more rigid giving it increased pressure-bearing capability, but this increased rigidity comes with reduced ductility, sometimes referred to as “brittleness”.

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.


CPVC tubing comes in nominal sizes ranging from 1/2 to 2 in. copper tube size (CTS), and pipe sizes ranging from 1/2 to 24 in. (Sch 40/80) iron pipe size (IPS). CPVC tubing is SDR11 (1/2 to 2 in.)

What is the burst pressure of CPVC pipe?

Burst Pressures: Safety Factor Considerations

At room temperature, FlowGuard Gold® CPVC is pressure rated to 400psi and at all normal operating temperatures (up to 140°F) FlowGuard Gold CPVC is pressure rated above 200psi.
