Most people don't think about the garbage disposal until the night it stops working. When it does, the kitchen gets a lot harder to use, and the sink above it often starts backing up too. It helps to know what wears a disposal out, what keeps it running, and when a repair makes more sense than a replacement.
What kills them is rarely age alone. It's the slow accumulation of the wrong things, fibrous stuff wrapping the impellers, grease building up until the motor strains, foreign objects that fell in unnoticed, and the classic, running it dry without water. The signs usually tell you a lot about what failed. A hum with no spin usually means a jam, which is often fixable. A leak underneath usually means the seals or the housing, and that can be fixable or a sign the unit is near the end of its life. Total silence usually means the electrical side or the motor, and a disposal with a dying motor usually isn't worth reviving.
Jams get cleared, fixable failures get fixed, and when replacement is the right answer, the options get laid out plainly, horsepower matched to how your kitchen actually cooks, installed properly with the plumbing connections done right, because a bad disposal install shows up as a leak in the cabinet. Everything gets explained in plain English so you can decide what to do.
