    Grey plastic pipe in heating system.

    Doing some decorating I discovered that some of the central heating pipe work is grey plastic. System installed 20 years ago by previous owners. My question is was that normal practice back then and is it likely to cause any problems in future? All exposed pipe work to rads is copper.
