We are your polybutylene pipe replacement experts. Polybutylene is a form of plastic resin that was used extensively in the manufacture of water supply piping from 1978 until 1995. Due to the low cost of the material and ease of installation, polybutylene piping systems were viewed as "the pipe of the future" and were used as a substitute for traditional copper piping. It was used through the 1980's and early-to-mid 90's.

These are typically gray or white in color with a dull finish. Most are shown with pipe attached. Figure (4) is a new fitting.
The piping systems were used for underground water mains and as interior water distribution piping. Industry experts believe it was installed in at least 6 million homes, and some experts indicate it may have been used in as many as 10 million homes. Most probably, the piping was installed in about one in every four or five homes built during the years in which the pipe was manufactured.

How to Tell If You Have Poly

Exterior - Polybutylene underground water mains are usually blue, but may be gray or black (do not confuse black poly with polyethelene pipe). It is usually 1/2" or 1" in diameter, and it may be found entering your home through the basement wall or floor, concrete slab or coming up through your crawlspace; frequently it enters the home near the water heater. Your main shutoff valve is attached to the end of the water main.

Also, you should check at the water meter that is located at the street, near the city water main. It is wise to check at both ends of the pipe because we have found cases where copper pipe enters the home, and poly pipe is at the water meter. Obviously, both pipes were used and connected somewhere underground.

Interior - Polybutylene used inside your home can be found near the water heater, running across the ceiling in unfinished basements, and coming out of the walls to feed sinks and toilets. Warning: In some regions of the country plumbers used copper "stub outs" where the pipe exits a wall to feed a fixture, so seeing copper here does not mean that you do not have poly.

Will the Pipes Fail?
Oxidants in the public water supplies, such as chlorine, react with the polyethylene piping and acetal fittings causing them to scale and flake and become brittle. Micro-fractures result, and the basic structural integrity of the system is reduced. Thus, the system becomes weak and may fail without warning causing damage to the building structure and personal property. It is believed that other factors may also contribute to the failure of polybutylene systems, such as improper installation, but it is virtually impossible to detect installation problems throughout an entire system.

Vancouver Water Line Experts can replace your polyethylene water line with new water lines:

•Pipe-splitting. A wedge is pulled through the polyethylene pipe splitting as it moves through the old pipe. A new copper pipe is pulled behind the splitter. The new pipe is installed without digging.

•Excavation with a trencher. A small trench is dug to replace pipe in areas where the freeze depth is shallow.

•Deep trench excavation. In areas where pipes must be buried deeper, and feeding the new pipe behind a splitter doesn't work, a deep trench must be dug the length of the main water line.

When a leak in your water line is detected, it is very important to have your polyethylene water line replaced as soon as possible. This will prevent any major damages from occurring in your home, such as the growth of mold and mildew, rotting floor joists and ruined drywall. Our water line plumbers are experts in the field of water lines and assure you we will get the job done right.
