STARSTAR Black Flange for 3-1/2 Inch Sink Drain

How to Install the Sink Flange

Step 1: Prepare the materials and tools. - Make sure you have the necessary sink flange, washers, and nuts. - Gather tools such as a rubber mallet, a screwdriver, and a wrench.

Step 2: Position the flange correctly. - Align the flange with the 3.5-inch opening of the sink, ensuring it is perfectly centered. - Gently tap the flange into place using a rubber mallet to avoid damaging the sink or flange.

Step 3: Secure the flange with washers and nuts. - Place a washer over the flange, then tighten a nut using a wrench. Apply a thin layer of plumber’s putty on the edges for a better seal.

Creating a Tight Seal Between the Top of the Sink and the Flange

Step 1: Apply plumber’s putty. - Butter up the edges of the flange with plumber’s putty to create a watertight seal. - Ensure the putty is evenly distributed around the flange.

Step 2: Apply even pressure. - Press the flange firmly against the sink, ensuring the putty is compressed. Use the rubber mallet to gently tap the flange into place again.

Additional Tips for Plumbers

Step 1: Check for leaks. - Turn on the water to check for any leaks around the flange. Tighten the nuts if necessary.

Step 2: Ensure compatibility. - This flange fits standard garbage disposal units with a 4.5-inch rim diameter and a 1-5/8-inch depth. - It is suitable for all types of garbage disposals, whether embedded or three-bolt processors, for a 3.5-inch standard socket.

By following these steps, you can easily and securely install the sink flange, ensuring a tight seal that meets your plumbing needs.
