Install New Washer

What happens here

With the internal stem assembly removed, locate the small screw at the end of the stem that holds the rubber washer in place. Use a screwdriver to remove this screw and the old, likely worn-out, washer. From an assorted flat bib washer and screw set, select a new rubber washer that precisely matches the size of the old one. The video indicates a 'double zero washer' was used in this instance. Apply a small amount of silicone grease to the new washer to help with sealing and to prolong its life. Secure the new washer to the end of the stem using the screw and screwdriver.

Goal: Replace the worn-out rubber washer causing the leak.
