How many years do garbage disposals last? One the average, quite a long time. In fact, with adequate care and proper maintenance, garbage disposal units can be of good service for about 8 to 15 years. This means the blades remain efficient and the motor has not burned out yet. This being said, neglecting garbage disposal leaks will significantly decrease this effective service life.
Trim the discharge tube as needed. If you’ve upgraded to a larger disposal or one of a different model, there’s a good chance that the discharge tube won’t be the right length to connect to the ground plumbing valve. Fortunately, this is a simple fix—mark the spot on the tube where it should line up with the drain pipe, then cut it to size with a hacksaw. It should be a perfect fit.[19]
Place a 1/2 inch rope of plumber's putty around the drain opening in the sink. Drop the new sink flange into the drain opening and press it into place. Placing a weight, such as a disposal, on top of the sink flange will help hold the sink flange in place while mounting the sink flange to the sink. To avoid scratching your sink or the flange, place a towel between the sink surface and the weight. (See Fig 4)
Garbage disposals first appeared in households in the 1930's and 1940's. These appliances, which are installed under a kitchen sink, can make a cook's life easier by trapping and shredding food waste items, allowing it to pass through the plumbing system. Although these popular appliances make cooking and cleaning much more convenient, they do require regular maintenance to keep them running at optimal performance. When it is time to replace your garbage disposal's blades, you can save time and money by doing it yourself.

Dispose orange peels, or any citrus rinds, to freshen the disposal and keep it smelling clean, but cut them into slices first as large pieces of citrus peel, e.g. half a lime, can jam a disposal. You can also use pieces of citrus fruit that may be too old to consume, as long as they're not too spoiled to smell nice. You can freeze these pieces first, if you wish.
Thanks so much! Clear, easy to follow instructions. We were able to follow step by step and got it done. I read somewhere that they used a car jack to hold the disposal when taking it off and putting it on. That was a really helpful tip for anyone else doing this. They’re fairly heavy. Also, it leaked when the gasket was just placed in the hole. We actually had to take it apart and put the gasket over the plastic pipe, then when you tighten the metal plate to connect it to the disposal, that sealed it. Anyway, thanks again. Being able to do this on our own saved us quite a bit of time and hassle.

Another common cause for a leaking garbage disposal is the disposal flange. A leak at the very most upper area of the garbage disposal could be the garbage disposal flange which goes through the sink. A garbage disposal flange should be sealed with Plumber’s putty and then tightened from underneath the sink. If this is not tight enough or if it has managed to come loose (which can happen) then the garbage disposal will have to be taken down so the flange can be resealed and then the garbage disposal can be rehung.
