Sealing Off the Overflow

Method 1: Using a Drain Plug

• Apply masking tape around the overflow opening, leaving a small gap for the sealant.
• Apply a bead of silicone sealant around the overflow opening, filling the gap.
• Smooth the sealant using a wet finger or a sealant tool.
• Remove the masking tape and allow the sealant to dry for 24 hours.

Method 3: Using a Plumber’s Putty

• Materials: Plumber’s putty, putty knife
• Instructions:
• Roll a small amount of plumber’s putty into a ball.
• Place the putty over the overflow opening and press down firmly.
• Use a putty knife to smooth the putty around the edges.

Method 4: Replacing the Overflow Gasket

• Materials: Replacement overflow gasket, screwdriver
• Instructions:
• Remove the overflow cover using a screwdriver.
• Inspect the gasket for damage or wear.

Tips for a Successful Repair
