Not only can CPVC be used above the maximum service temperature of PVC, but its increased temperature resistance enables it to perform better at temperatures within PVC’s working range. For example, even below 140°F (60°C), CPVC is superior to PVC in terms of impact strength and tensile strength.
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 is the advantages of CPVC over PVC?
Because of its makeup, CPVC is immune to damage from highly chlorinated domestic water and has a higher temperature tolerance than PVC. Chlorine-based disinfection is used by water companies to kill disease-causing bacteria before water enters your home.
What is a disadvantage to CPVC?
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.
Which is cheaper PVC or CPVC?
PVC is less expensive than CPVC, and both materials are cheaper than copper, iron or stainless steel pipes. PVC pipes are sized by the nominal pipe size (NPS) sizing standard (NPS references the pipe interior diameter).
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. Cut the CPVC pipe to size with a fine tooth saw.
Which pipe is better PPR or CPVC?
1. Physical Properties. With 60% greater tensile strength and nearly twice the flexural strength, CPVC is a stronger, more durable piping material than PP R. Due to its strength, CPVC can withstand more pressure, which means same flow rate with smaller pipes.
Which pipes are best for plumbing?
Copper pipes are probably the most traditional plumbing pipe used due to their extensive duration and reliability. They provide superior corrosion resistance, great material to be used for hot and cold water, and it can be managed easily.
Why is PEX better than CPVC?
Some plumbers prefer PEX in new home construction over CPVC because of its flexibility, resistance to failure by freezing, and resistance to chemical attack when in contact with other products containing chemicals.
How long does CPVC pipe last?
Chlorinated polyvinyl chloride (CPVC) pipe is a thermoplastic created by the chlorination of polyvinyl chloride (PVC) resin. It has been available since the mid-1960s, and has an estimated lifespan of 50 to 80 years, with an average of 70 years.
Should I use CPVC or PEX?
CPVC is More Effective at Maintaining Water Quality than PEX
Third party studies show that CPVC piping, such as FlowGuard Gold pipes and fittings, consistently demonstrate a lower risk of biofilm formation than PEX.
Why do CPVC pipes fail?
Failures occur when the combination of stresses exceeds the strength of the original material that has already been reduced by quality issues or chemical stresses. The reverse is also true: high-quality processed CPVC may be able to withstand some mechanical stress and contact with chemically incompatible materials.
Which is better HDPE or CPVC?
The CPVC show good performances toward the supported internal pressure, support up to 160 bars, and a brittle behavior. Meanwhile, the HDPE pipe can support up to 70 bars and show a ductile behavior.
Why is CPVC used for drinking water?
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.
Can you use PVC for drinking water?
Most schedule 40 PVC found in homes and offices is white pipe with a National Sanitation Foundation (NSF) rating for potable water.A possible solution is to replace your PVC pipes with an approved material such as CPVC (a stronger type of PVC) or copper. Both materials are considered safe for potable water.
Can you use PVC for cold water lines?
PVC is normally used for cold water pipes only, as heat can eventually break down the plastic. Always check with local code restrictions before using PVC pipes for hot water delivery lines. In homes plumbed with first-generation plastics, the cold water lines are often PVC, with CPVC used for hot water lines.
Can oatey PVC cement be used on CPVC?
This milky-clear, low VOC, all-purpose cement can be used to solvent weld all schedules and classes of ABS, PVC and CPVC pipe and fittings up to 6 in. diameter with interference fit. Oatey products have earned the trust of plumbing professionals for over 100 years.
What color is CPVC glue?
Orange
Oatey Medium Orange CPVC Cement

Do PVC and CPVC have the same OD?
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.
What is the best pipe for hot water?
CPVC
Chlorinated Polyvinyl Chloride Piping (CPVC)
CPVC is suitable for hot water and drinking water, unlike normal PVC. Compared with copper, CPVC pipes are smoother, and they produce less noise when water flows through.
Which CPVC pipe is best?
As one of the best cPVC pipes and fittings, Ori-Plast products are versatile to fit a diverse range of applications and come with ISI mark (ISI 15778) and with global quality standards certification of ASTM F441/F441M. Ori-Plast is a leading brand in the field of plastic pipes and fittings for the last 5 decades.
