1950 built house.
At sometime sewer and water line replaced both in same trench.
Sewer is ABS.
Water line is some type of blue poloy pipe. Was is it?
A light color blue and not like the old blue/grey quest pipe.
Was connect with a barb fitting and hose clamp just like I have seen with the black poloy pipe used for main water lines.
Looks and feels like the black poloy pipe but a blue color.

thanks
