Polybutylene Pipe: What Twin Falls Homeowners Should Know

Grey polybutylene pipe was used in many U.S. homes built from about 1978 to 1995.

How to spot it

Look for grey (sometimes blue or black) flexible pipe near the water heater, under sinks and at the main shut-off. It is often stamped "PB2110".

Grey polybutylene water pipes under a floor, joined with grey plastic fittings and copper crimp rings, with PB2110 printed on the pipe — What polybutylene looks like: grey flexible pipe, grey plastic fittings held by copper crimp rings, and printing on the pipe that includes “PB2110”.

Why it matters

Fittings and pipe can become brittle with age and fail without warning, causing water damage.

Insurance

Some insurers ask whether a home has polybutylene and may charge more or limit coverage. Ask yours what they require.

Your options

Replace it all at once, replace it in stages, or keep an eye on it. See polybutylene and repiping.
