Leaks in plastic water supply piping: this article describes the causes of damaged or leaky buried plastic water pipe & resulting poor water pressure, poor water flow, or water leaks in water piping between a well or municipal water service main & the building. Knowing just what kind of leak is occurring in a building helps pinpoint the problem and also helps specify the necessary plumbing repair. The articles at this website will answer most questions about diagnosing and repairing pumps, wells, water supply systems, and building piping.

If your building water supply is provided by a private well see WELL PIPING LEAK DIAGNOSIS. Also see Water Supply/Drain Pipe Leak Types and see Thawing Frozen Pipes which addresses how to find frozen and burst pipe leaks in buildings, and see Repairing Burst Leaky Pipes.
Leaks in Municipal Water Service Piping
As Carson Dunlop's Home Reference Book points out,
While the comments below originally described the cause of a leak in plastic well piping, the same conditions can cause a leak in buried municipal water supply piping between the building and the street. As Carson Dunlop's Home Reference Book points out,

Defective PVC Polyvinyl Chloride Pipe Production, Leaks, Explosions, & Whistle Blower Lawsuit - JM Eagle
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.
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..."
The Kitec system was a collection of brass plumbing connectors intended for use with PEX type plastic piping. Kitec, also in some sources spelled Kyetec is a brand of brass plumbing fitting that was recalled in 2005 by its manufacturer, IPEX, due to its tendency to quickly corrode. - Wikipedia  For details about PEX piping see PEX PIPING INFORMATION
Because Kitec PEX fittings were used widely across the U.S. and under other names (below) in areas of Canada, the risk of plumbing leaks due to corrosion (dezincification) at these brass-to-PEX connectors & fittings continues in homes where they have not been replaced.
How to Identify Kitec or IPEX Plastic PEX Piping Connectors & Fittings
The Kitec Class Action Settlement
Kitec plastic pipe and fittings has agreed to settle class-action suits in the United States and Canada for $125 million. The piping system that is the subject of this action was used in roughly 292,000 U.S. and Canadian homes beginning in 1995. Quoting

Kitec Kytec IPEX Class Action settlement details
The settlement covers properties where Kitec plumbing (typically blue plastic for cold water lines and orange for hot water lines) was used in both the U.S. and Canada (excluding Clark County NV, the subject and area of a previous Kitec pipe plumbing failure case in the mid-1990s.). There are also distinctive brass connecting fittings (photos at the Kitec website). After attorneys fees, administrative costs and payments to the class representatives in the suit, more than $93 million is expected to be available for claims.
The distribution plan anticipates two payment steps, starting with an eight-year period for initial claims based simply on the cost of repairing or replacing the broken pipe or failed fitting. If there’s money left over after the first phase, a second, pro-rated, payment would be sent out to offset the costs of having the plumbing replaced or cover other uncompensated damages. People must decide if they’re in or out of the settlement by Sept, 30, 2011 and if they opt out, must notify the judge and attorneys for both sides in writing. Judges in Dallas, and in two Canadian provinces will hold fairness hearings on the proposed settlement between Nov. 17 and Dec. 1, 2011. A website has been set up to administer the settlement, as we detail just below. Quoting:
ALL PERSONS THAT OWN, HAVE OWNED, LEASE, OR HAVE LEASED, AND ALL THOSE WHO HAVE OR MAY PURSUE CLAIMS THROUGH OR IN THE NAME OR RIGHT OF THEM, buildings, HOMES, RESIDENCES, OR ANY OTHER STRUCTURES IN THE UNITED STATES AND CANADA THAT CONTAIN, OR AT ANY TIME CONTAINED, KITEC PLUMBING SYSTEMS AND/OR COMPONENTS. YOUR LEGAL RIGHTS ARE AFFECTED WHETHER YOU ACT OR CHOOSE NOT TO ACT. PLEASE READ THIS WEBSITE CAREFULLY. 
Kitec class action settlement deadline
As of the latest information we have found, homeowners wishing to file a claim to participate in the Kitec® PEX settlement needed to file a claim by 31 March 2012.
The claims adiminstrator's website is www.TotalClassSolutions.com/Settlements/Kitec.
The Kitec class action legal counsel can be contacted at:
In March 2012 the U.S. District Court for the District of Minnesota court-ordered homeowner notification program was scheduled to begin. People who own or previously owned a building where Plumb-PEX plumbing components were installed are notified of a proposed class action settlement involving Radiant Technology, Inc. and Uponor, Inc who sold Plumb-PEX insert fittings and stainless steel PEX tubing clamps. Those components may have leaked, or may leak, causing building damage. The defendants denied all claims of the lawsuit but have agreed to settle the case. 
Plumb-PEX Settlement Details
RTI Plumb-PEX Plumbing System fittings and components including
Plumb-PEX Settlement Provisions
The settlement reimburses for property damage caused by a qualifying leak in the Plumb-PEX installation, and it provides for possible repair or replacement of the RTI Plumb-PEX installation in structures suffering two or more "qualifying" leaks.
Plumb-Pex Class Action Settlement Deadline
Watch out: If you are eligible for a claim under the Plumb-PEX settlement, you must file your claim within 18 months of the notification date of 22 March 2012
