Secure the ring by breaking the round clip springtime or break ring right into the groove on the flange tailpiece.

3. Tighten Up the Placing Ring Assembly
Tighten down the mounting setting up by tightening the three mounting screws, tightening up each a little at a time to gradually apply also stress. Tighten up the screws until the sink flange is tight against all-time low of the sink as well as excess plumbing technician’s putty has actually oozed out around the drain opening.

When the drain connection is made, link the dishwashing machine line, as appropriate. Move the dishwater hose onto the disposal nipple, and protect it with the clamp given by the maker.
