Underground water line - what type of pipe should I use?

Don Crump
by Don Crump
I need to replace about 1800 ft. of underground polybutylene water pipe that supplies water to my house from the connection at the street. Most people I've talked to say to use PVC that I can get in 20' segments and glue them together. But that would mean about 90 glued joints under the ground. If I do that, I'll be lying awake at nights worrying about leaks. I've done some research online and it seems my other alternatives with fewer joints are polyethylene and PEX. They come in rolls that I can find up to about 500 ft. That's a whole lot fewer joints and I can sleep with that! What do you say?
Thanks,
Don

  • You need to purchase the Poly. Although Pex may work fine, you need to check if the Pex can be buried. There are different brands of Pex as well as different types. Do not use PVC. Its not used for water as it can release harmful chemicals. I would however before you even go that far, is to check with the township on this. They may have special requirements on what type of pipe you can use. Also you will need to be licensed and bonded to connect to the street supply. Unless your making your connection past the meter where you are responsible for the pipes.
