garbage disposal collarIf your garbage disposal has died and you need to replace it, you may be able to cut half the time of the installation…depending.

\

The mounting collar (aka ring or flange) is what holds the disposal to the bottom of the sink. You put plumber’s putty on the underside of the top half of the collar and place it in the hole of the sink. The bottom half mates with the top and then there is a tricky snap ring that holds them together. If these parts look good and are not leaking, you might be able to get away with not replacing them…if you buy the same brand.

\

Generally, disposal mounting rings are useful for only the manufacturer’s disposals. So if you buy the same brand and the old collar looks good, you might consider leaving the old collar in place and just twisting on the new disposal. If you change brands then go ahead and replace the collar.

The only thing you will save here is time. The most challenging part of the installation is the collar, so if you can avoid it you will save a little time. A new garbage disposal will come with the new collar, so if you want to , go ahead and replace it.
