Fixing a leaky PVC pipe is quite simple and involves searching for the source of the leak and using rubber sleeves and fiberglass tape to seal off the leak. Leaks can run up utility bills and cause physical damage to the surrounding structures; fixing the leak as soon as possible will help keep the damage minimal and avoid costly repairs.Know More
The following steps show one method fixing a leaky PVC pipe.
Search thoroughly for signs of leaks. Mark the areas where the leaks are spotted.
After marking the area or areas where the leaks are, turn off the main water supply line.
Turn on the taps to relieve the remaining water pressure in the pipes. Make sure to completely drain the remaining water in the pipes.
Neoprene couplers, which look like rubber sleeves, can be used to seal off a leaky pipe. Often used as a device to secure two pipe joints, the rubber sleeves are held in place either by a C-clamp or a stainless steel hose clamp. If these devices are available, use them on the leaking area on the pipe.
Alternatively, a fiberglass tape may also be used to seal a leaky portion of the pipe. However, make sure that the pipe is dry when taping up the section and allow for the tape to settle into the pipe for 10 minutes before turning on the water supply again.
PVC glue can be used on CPVC pipe but doing so will often result in leaks and degradation of the seal on the joints, so it is not recommended. PVC and CPVC are made up of similar chemical elements, but they are not interchangeable.Full Answer >
To bend PVC pipe, put a cap on one end of the pipe, fill it with clean, dry sand, then put a cap on the other end as well. Next, heat the pipe and the sand carefully with a heat gun, then bend the pipe slowly into the desired shape. Allow the pipe to cool for at least several minutes and then empty the sand from the pipe.Full Answer >
CPVC pipe differs from PVC pipe in that it withstands a wider degree of temperatures and contains more chlorine. PVC pipes can handle temperatures up to 140 degrees Fahrenheit according to ASTM standards. CPVC pipes can take temperatures up to 190 degrees Fahrenheit.Full Answer >
The "Standard Specification for Poly(Vinyl Chloride) (PVC) Plastic Pipe, Schedules 40, 80, and 120 guide," also listed as the ASTM D1785, lists the outside and inside diameters and wall thicknesses for PVC and CPVC pipes between 1/2-inch to 16-inches in size. The most common are Schedule 40 and 80 pipes.Full Answer >
