This document provides installation instructions for sealing and testing a drain cover. It lists the bolt and washer specifications for three manufacturers - Zurn, Watts, and Smith. The instructions explain that the user should remove all parts from the package and check that the correct number of o-rings, bolts, and washers are included. The o-ring must be securely seated in its groove to create a water-tight seal. Then the bolts and washers are placed through the cover holes and lined up with the drain holes before tightening the bolts to 40lbs of torque.
