Several new items have been added to the ChemDrain line of chlorinated polyvinyl chloride (CPVC) chemical waste drain systems, including 8-in. pipe and fittings and a variety of drains. The 8-in. fittings include 1/4 bends, 1/8 bends, 1/16 bends, sanitary tees, wyes, combination wyes, reducing wyes, couplings, bushings and cleanout adapters. CPVC piping systems have a high temperature rating and are resistant to a wide range of chemicals, including acids, bases, caustics, salts, aliphatic solutions and other common agents used in chemical waste processes.
