Sink Repair questions, answered by experts

Once you have your garbage disposal disconnected, you can remove the mounting bracket by unscrewing the bolts that are holding the bracket. You can back them out just enough to pop off the snap ring, which prevents the bottom portion of the bracket from disconnecting from the top when you unscrew the bolts. Use a regular screwdriver to pop off the snap ring, and the rest of the components should fall off by themselves.

Yes, plumber's putty ensures a solid bond between the drain assembly and sink. Silicone is a good alternative if you prefer not to use plumber's putty. However, plumber's putty typically isn't visible from the outside of the drain, as you can wipe away any excess when done.

Yes, it is often possible to replace an undermount sink without removing the countertop, but success can depend on the countertop material. For materials like granite, the process is relatively straightforward. However, laminate or uniquely shaped countertops might need to be removed or modified.

The process typically involves shutting off the water supply, disconnecting the drain and plumbing pipes, cutting through the old silicone seal, and carefully lowering the sink from below. This requires a good understanding of plumbing and the right tools. If you are not confident in performing the replacement yourself, it is recommended to hire a countertop specialist or a plumber to handle the task.

While unplugging your garbage disposal and plugging it back in may help, most units have an actual reset button, a bright red switch found on the underside of your unit. If your garbage disposal needs resetting, you may notice this button sticking out about a quarter of an inch from the surface of the unit, with which it’s usually flush. Simply depress this reset button to reset the unit, and then test to ensure it’s working about 10 minutes later.

Leaks, clogged drains, cracked basins, and worn-out seals are common problems that may require professional repair.
