Installation Notes
Before fitting, check that the waste outlet and waste pipe are suitable for a 40mm / 1½” trap. Cut the waste pipe cleanly and make sure it is fully seated inside the Multifit compression outlet. Tighten the compression nuts securely by hand, then run water through the waste and check all joints for leaks.
