I have a white sink with a disposal, and the chrome flange just doesn’t look good with the white sink. Do they make a white flange for this, and if so, is it something easy to replace?
You are in luck! They certainly do make a white disposal flange, and it isn’t very hard to replace it.
Once you have the flange and are ready to start, I would suggest lying a thick towel down on the cabinet lip. You’ll see why in just a few minutes of working inside the cabinet, lying on your back. Begin by disconnecting the pipe leading from the disposal to the drain. If you have PVC drain pipes, you may be able to loosen the couplings by hand, but if not, use a pair of channel–lock pliers. Once the drain is away from the disposal, you’re ready to remove the disposal from its mounting.
From below, just at the top of the disposal, you will see a ring (usually chrome colored) with a loop. Using the disposal wrench (an elongated “S” tool), insert it into the loop (using a screwdriver if you don’t have the wrench), then turn the unit clockwise. Be prepared as you do this, as the disposal will drop down into your hands, and it is somewhat heavy. When it does come down, set it aside.
Next, you will see a retaining ring which surrounds the flange. Using a screwdriver, pry one end of the ring down and the rest of the ring will come off. Be patient here; getting this ring on and off is usually the hardest part of the job. When the ring is off, unscrew the three screws which compress the mounting ring from the flange. You’ll then be able to drop the mounting ring from the flange. With that done, push the flange up and into the sink.
You’re now ready to install the new flange. Take some plumber’s putty and roll it in your hand to form about a ½” snake, which you will wrap around the rim of the flange. Set the flange into the hole, and if there is any writing on the top of the flange (the manufacturer’s name), it looks better if this writing is readable from the top. Next, you’ll simply reverse the process of installing the mounting plate.
Before you’re able to tighten the flange, the retaining ring has to be reinstalled. If you have any trouble, it may help to have someone press down on the flange from above. With the mounting ring secured, lift the disposal in place, insert the wrench and turn the ring counter-clockwise to tighten it. Reconnect the drain pipe and test for leaks. You’ll notice that the plumber’s putty has squeezed out from the new flange. This is normal. Just scrub the excess away until you can’t see any more.
