PVC or chlorinated polyvinyl chloride plastic plumbing pipes:
This article describes the properties of polubutylene PVC & CPVC plastic piping and tubing used in buildings. We include information about failures and problems with some generations of CPVC or PVC plastic pipes and we describe good building practice installation details where plastic piping is being installed.
The articles at this website will answer most questions about plastic building water supply and building drain piping products, failures, and claims as well as many other building plumbing system inspection or defect topics.

Chlorinated polyvinyl chloride (CPVC) pipe is not as flexible as PB or PEX and the fittings are solvent welded (glued) rather than press-on. This pipe is likely to split if freezing occurs. CPVC pipe is suitable for use on both hot and cold water lines. - Home Reference Book, used with permission.

Watch out: PVC polyvinyl chloride pipe produced by JM Eagle Corp. is reported to be defective, leaking or breaking as early as in the first year after installation. Details are
Watch out: Using the wrong solvent adhesive, or not using it properly (including pre-cleaning the pipe joints) not only results in leaky plumbing, also the purple solvent cement makes permanent stains, as Oatey Plumbing points out:
PVC is Poly(Vinyl) Chloride, CPVC is Chlorinated Poly(Vinyl) Chloride and ABS is Acrylonitrile-Butadiene-Styrene.
PVC and ABS pipe are normally used for drain, waste and vent (DWV) systems.
CPVC is used for water distribution systems. It is important to choose the correct solvent cement or pipe glue based on the type of plastic pipe being used.
Our photo (left) shows a close-up of markings on PVC sewer piping. Note that we took this picture of pipes resting on a gravel driveway. You should not bury plastic sewer piping in sharp rocks but rather it should be bedded in sand and located 18" below the ground surface or deeper to reduce chances of damage from rocks or from vehicles passing overhead.

The following is excerpted from PLASTIC PIPE LEAK CAUSES
Early in 2010 New York Times reported that John Hendrix has accused PVC piping manufacturer JM Eagle of falsifying PVC pipe quality testing results, covering up the discovery that pipes that should last 50 years are failing as early as in one year, risking costly leaks and dangerous explosions.
Hendrix, former overseer of certification of a manufacturing process that tested PVC piping produced by JM Eagle said that the company had been selling substandard polyvinyl chloride or PVC piping since 1996 and that the company had manipulated pipe testing results. Hendrix said, according to the Times report, that less than half of JM Eagle's PVC pipe production met the required quality standards.
JM Eagle produces roughly 60 percent of plastic water piping sold in the U.S. and also distributes its products in Canada and Mexico.
Indeed the same Times article reported that some U.S. municipalities have already found leaking, cracking, and exploding PVC pipes made by JM Eagle, and some are joining the "whistle blower" lawsuit as a result. Litigation has been filed in the U.S. District Court for Central District of California, and has been joined by California, Delaware, Nevada, Tennessee, and Virginia. The Nevada state attorney general cited JM Eagle pipe that had been rupturing several times a year.
The article reports that Hendrix asserts having been trained to look for ways to blame PVC polyvinyl chloride piping leaks and breaks on the installing or maintaining contractors, but after being assigned to oversee pipe testing Hendrix found that the company was using lower grade raw materials (from Formosa) and had sped up pipe production without reporting these changes to pipe certifying agencies as required. He was fired.
JM Eagle disputed the allegations and said that tests were properly conducted and that the company stands 100% behind its products. JM Eagle Corporation is successor to Johns Manville Corp. and was created in 1982 after Johns Manville Corp. filed for bankruptcy to seek protection from asbestos claims.
In 1982 Johns Manville Corp's pipe division was bought by Formosa Plastics Group, a Taiwanese industrial group owned by Wang Yung-Ching, and at that time renamed JM Manufacturing, later renamed again to JM Eagle in 2007.
In April 2010, again reported in the NY Times, JM Eagle promised to guarantee its products for 50 years, including pipe that is already in the ground. "The warranty covers the pipe based on standards that were in effect at the time of the installation," the times reported. Links to and excepts from the JM Eagle pipe warranty are provided below at References.
Watch out: the same April 2010 Times article points out that municipalities had already reported pipe failures that "... may not qualify for a claim against the new guarantee..."
