“`Frequently Asked Questions
How do I know if my garbage disposal leak is coming from the sink flange?
Look for water pooling directly beneath the sink flange where the disposal meets the sink basin. If the leak appears at the very top of the unit rather than the sides or bottom, a failed flange seal is almost certainly the cause.
Do I need to replace the entire garbage disposal to fix a flange leak?
No, you typically only need to reseal or replace the sink flange itself. This is a straightforward repair that leaves the disposal unit intact.
What type of plumber’s putty should I use when resealing the sink flange?
Use a standard, non-staining plumber’s putty for most kitchen sinks. If your sink is made of granite or composite material, choose a silicone-based sealant instead to avoid discoloration.
