I bought a whole house water filter to hook up to the main water line. The plumber who came in said that he won't be able to install it because the pipe that comes from the ground hooked up to the copper pipe is plastic.
He says that this plastic is usually not used for that kind of water pressure for the main line and can burst at any time. If he starts cutting the pipe above it to hook up the water filter, there is a potential that the plastic could break/leak due to all the shaking etc. He has asked me to contact the builder/home inspector (as it shouldn't have passed the home inspection like that? ) and take care of this first.
Picture is below. The black color pipe is the one in question. Has anyone seen plastic pipes come up from the ground like that to the main line? Will it burst?
Update - new pics and details
Close up pictures on request. I looked the pipe closely. It is written 1 1/2" 0.1 / Plastic. (above the first ring at the bottom, you can see it in the second pic). House is built in 1993.
