Due to its flexibility that allows it to expand and contract, PEX pipe is considerably more burst‐resistant than plastic pipe that is rigid and prone to cracking. CPVC is chemically welded together with solvent and glue. It was a two story house. Like CPVC, PEX has a higher thermal expansion coefficient than metal – it expands 1 inch per 10°F per 100 ft. length. PVC is still more commonly used for cold water and waste pipes, where it’s cheaper to use. PEX can also withstand high pressure. To help you make the best decision for your specific needs, we've taken the time to lay out the similarities, differences, benefits, and drawbacks of each type of pipe. Note: Using PEX tubing in a home run configuration may cost an additional $100-$250 for the multi-port manifold that divides the incoming hot and cold and sends it to the entire home. CPVC is more of a vanilla/cream color, and it comes in stick pipes where the fittings need to be glued together. This can lead to leaks that can be difficult to detect if they aren't in a place that's readily visible. CPVC piping systems, such as FlowGuard Gold piping systems, are immune to chlorine degradation due to the presence of chlorine in its polymer structure. BlazeMaster CPVC pipes, produced in SDR 13.5 dimensions with a Hazen-Williams C factor of 150, can improve the performance … PEX plumbing has been in use in Europe since about 1970, and was introduced in the U.S. around 1980. Plumbers installing FlowGuard Gold pipes and fittings can also save money. hbspt.cta._relativeUrls=true;hbspt.cta.load(4298533, 'dd7f08f4-1d20-46fa-ac6a-0a0289f667cc', {}); The ink from the print line on this PEX pipe has permeated almost completely through the pipe after less than 10 years. Recent third party research conducted by Home Innovation Research Labs, a subsidiary of the National Association of Home Builders (NAHB), found that CPVC installs about 15% faster than PEX in its most common configuration. PEX pipe is easy to install, requires fewer connections, and costs less per linear foot than other pipe options. The moral of this blog post is that you should always go with CPVC or copper. The test shows that CPVC pipes have a pressure rating of 73°F that is equal to 22.8 degrees in Celsius. Active 3 years, 3 months ago. FlowGuard Gold CPVC will not allow outside contaminants to enter your drinking water through the pipe without causing the pipe to fail. While a FlowGuard Gold plumbing system will never fail under normal use due to chlorine levels, ASTM F2023 is required to determine a time-to-failure for PEX systems under normal use conditions with chlorinated water. PEX is only tested to resist chlorine at levels up to 4.3ppm, and the use of chlorine-based disinfectants reduces the temperature rating of PEX by 40°F (from 180°F to 140°F.). Copper Pipe vs. PEX Pipe Copper Pipe . Choosing between CPVC “Chlorinated Polyvinyl Chloride” and PEX “Cross-linked Polyethylene” water supply piping for a replumb or new construction application can be a difficult decision that requires careful thought. just measure, cut and glue fittings together. PROS OF CPVC PIPE. Copper pipes are metal and more durable, while PEX, PVC, and CPVC pipes are plastic and tend to have a shorter lifespan. The presence of hot chlorinated water is known to cause PEX pipe to degrade causing pinhole leaks and pipe failures. These two materials may seem similar due to their flexible nature, but their composition, application, and installation, are totally different. Recent third party research conducted by Home Innovation Research Labs, a subsidiary of the National Association of Home Builders (NAHB), found that CPVC installs about 15% faster than PEX in its most common configuration. There’s good reason for that – they are tremendously durable and … PEX — Cross-linked Polyethylene. Because it is well insulated, both hot and cold water retain their temperatures for longer periods of time. And PEX fittings, including the body and crimp rings, typically cost several times more than comparable CPVC fittings, and take two to three times longer to properly assemble. Ultraviolet rays can come from the sun, fluorescent bulbs or new CFL lightbulbs. PEX Plumbing. My old house built in the 70s had galvanized pipe which developed small leaks and we replaced it with PEX pipe. It’s commonly found in hydronic heating and cooling systems, insulation material for high voltage electrical wires, piping natural gas, chemical transportation, sewage systems, and water lines. PEX, like polybutylene, is a European technology that is less resistant to water conditions and chlorination commonly found in the United States. This natural immunity means a CPVC system can withstand chlorinated water at the temperatures and pressures where PEX will fail. PEX piping has been used in hot- and cold-water distribution systems and for hydronic radiant heating in Europe for decades. I used it for quite a few years actually when I build on the Northeast and had a success of it. Whether you live in the far north where winters are long or in the desert southwest where temperatures can be sweltering in the summer, PEX pipe is sure to maintain its integrity.

CPVC pipe is also resistant to chemicals, their residues, and scale buildup, meaning that the purity of your water won't be compromised. CPVC can degrade more quickly, and it can split. To start, PEX pipe is approved for hot and cold water plumbing systems and recirculating/hydronic heating systems in all mechanical and plumbing codes in the U.S. and Canada. Under these conditions, PEX can fail rapidly – in some cases in less than 10 years after installation. The fittings used to fix CPVC pipe can crack or warp if they are dropped or the foundation of the structure shifts during a remodel or earthquake. According to a 2018 technical note issued by the Plastic Pipe Institute (PPI), it was found that any combination of these factors can significantly reduce the service life of a PEX pipe. If a CPVC joint is going to leak, it will do so in the first 12 hours under pressure. If any part of your water distribution system is exposed to sunlight, PEX pipe won't last. The main difference between CPVC and PVC is the range of temperatures each is capable of withstanding.CPVC can handle temperatures up to 200° Fahrenheit, while PVC peaks at 140° Fahrenheit. PEX is basically a flexible tubing that’s used for water piping. FlowGuard Gold pipes and fittings provides a straight, professional appearance, eliminating disorganized runs that make the installation look unprofessional and use more materials per home. CVPC pipe is made of thermoplastic and is used in sprinkler and drain lines as well as water‐based heating systems. PEX piping is known to leach regulated substances, including gasoline components such as MTBE, ETBE, TBA and Toluene, into drinking water. In addition, third-party research has found that CPVC installs about 15% faster than PEX in its most common configuration. So, PEX is no less! Is there something else you are looking for? Pex piping has been around for more than 35 years with over 12 billion feet of tubing installed worldwide and is backed by a 25 year warranty when installed by a trained professional.

Both types of pipe have qualities that make them especially useful in certain situations and not so much in others. It is made from high-density polyethylene that has cross-linked bonds in the polymer structure. CPVC is corrosion-resistant. Price. In some cases, just 1 month of exposure to UV rays can reduce the time-to-failure of PEX by up to 21%. It can also come free from its connections, leaving you with a lot of bills for repipe repair. CPVC is also resistant to corrosion and to freezing pipes, but it is not quite as durable as PEX.

While the PEX tubing may carry a temperature and pressure rating of 100psi at 180°F, the pipe is not listed to perform under those conditions in the presence of chlorinated water. This can cause leaks or allow heat to escape, meaning affected areas might not thaw. Also, PEX is susceptible to oxidative degradation and embrittlement when exposed to hot chlorinated water, while CPVC isn’t susceptible to attack by chlorinated water. Not only do FlowGuard Gold pipes and fittings have superior permeation resistance, but they are also backed by the FBC System Compatible program to assist manufacturers of ancillary products in determining their product's chemical compatibility with FlowGuard Gold CPVC.
