CPVC piping is used in many residential, commercial and industrial plumbing systems. This type of pipe is ideal for moving all types of water from hot and cold potable to acidic water. As of 2010, CPVC piping has been approved by all building codes in the United States. Manufacturers of plastic piping are subject to the National Sanitation Foundation’s auditing system.
Consumers can purchase lengths of CPVC piping in a limited range of diameters and tube thicknesses. Typical CPVC piping for plumbing applications is available in sizes ranging from between 0.50 to 16.0 inches, according to Engineering Toolbox. Metric sizes are as readily available as standard sizes. Pipe fittings made out of CPVC tend to be bulky because of technological limitations.
This type of piping is considerably lightweight, lighter than all other types of piping approved for use in plumbing, according to Builder’s Websource. Their lightweight construction makes them more prone to cracking. They are more prone to crack than most other types of piping on the market. CPVC piping is very susceptible to cracking during an earthquake.
One of the biggest advantages linked with plastic plumbing is that it is quite resistant to condensation, abrasion and corrosion. CPVC piping remains some of the cheapest piping on the market and is considered to be the easiest type of piping to install. According to Savvy Café, the flexibility of CPVC piping eliminates water hammer. High impact strength and non-conductivity are two more benefits offered by this type of piping.
Despite the many benefits, there are certain disadvantages linked with CPVC piping. This type of piping can easily melt when exposed to flame and will encourage bacterial growth if improperly maintained. Some consumers have noted a plastic-like taste associated with drinking water distributed through CPVC piping. Savvy Café claims that some of the solvents consumers use to join together plastic plumbing components contain volatile organic compounds (VOCs).
