Whether you’re putting in a new sink or simply replacing old piping, Oatey’s catalogue contains all the necessary tubular piping for any type of plumbing scenario. Piping comes in plastic, brass and semi-cast material; although, any type of pipe material can be combined with another. Tubular also comes with and without a cleanout--a fitting that is used to easily access plumbing for cleaning without having to remove the entire fixture. Piping also comes in different diameters, including 1-½ in. (suited for kitchens and laundry rooms) and 1-¼ in. (typically suited for bathrooms).
