Plastic is resistant to frost. If during the freezing of the water in the drain there is a deformation of the pipe, then when thawing ice, plastic will restore its shape. Plastic structures are made of rubber seals. Plastic can expand in strong heat. But, the rupture of the details in the design will not occur, because the rubber seals give the mobility of the entire structure. If, instead of rubber compounds, glue is used, then special elements of expansion material are installed, which will provide mobility of the parts of a plastic drainage.
