	PVC pipe is not as commonly used due to concerns with lack of watertightness and other inherent disadvantages. The major disadvantage with PVC pipe is the bell and spigot joint connections. This type of joint connection has the potential for leakage or can separate as the embankment dam settles. The bell and spigot joint integrity must be tested for leaks to ensure that the gasket has not rolled off during installation. Use of PVC bell and spigot joints should only be considered for nonpressurized, low hazard dam applications. PVC is typically available in sizes up to 48 inches in diameter.

PVC pipe is not as commonly used due to concerns with lack of watertightness and other inherent disadvantages. The major disadvantage with PVC pipe is the bell and spigot joint connections. This type of joint connection has the potential for leakage or can separate as the embankment dam settles. The bell and spigot joint integrity must be tested for leaks to ensure that the gasket has not rolled off during installation. Use of PVC bell and spigot joints should only be considered for nonpressurized, low hazard dam applications. PVC is typically available in sizes up to 48 inches in diameter.
