Your garbage disposal gasket is the top rim where the rubber seal mounts to the flange. If your disposer is leaking from this area, the cause could be a leaky gasket. Gasket leaks can have several causes: ageing gaskets can develop leaks; long periods of disuse can dry the gasket and cause it to leak; if your garbage disposal was removed and then replaced, the gasket may have been improperly sealed; if the gasket is not locked evenly on all three sides, it will leak.
Garbage disposals are considered nearly essential for modern kitchens. Installed underneath the sink, they grind up food into particles that will easily flush down a drain. A common problem with garbage disposals is that they will become jammed if too much food is pushed into them or a foreign object falls inside. When jammed, the circuit breaker may trip, cutting the power to the unit. When that happens, it will appear that the garbage disposal motor has burned out even though that may not be the case.
A garbage disposal unit (also known as a garbage disposal, waste disposal unit, garbage disposer, or in Canadian English a garburator) is a device, usually electrically powered, installed under a kitchen sink between the sink's drain and the trap. The disposal unit shreds food waste into pieces small enough—generally less than 2 mm (0.079 in)—to pass through plumbing.
What's up with that scary loud noise when you turn it on? There are some reviews that make this sound like it is eating a spoon (a LOUD, disturbing, and/or startling snap or click noise, etc.). I have to say that was one of my biggest reservations when I ordered this thing, having read the reviews. A fairly large slice of reviewers commented negatively on it. Here's my take... The motor is 3/4 HP compared to my little dinky 1/3 HP motor on my old one. That is a lot more horsepower and, consequently, a lot more torque. The little "teeth" that do the waste grinding that sit in the base of the chamber spin freely. When you turn it on, the little grinders snap into place like how your head gets whipped back on one of those crazy spinning carnival rides. It's just from centrifugal force setting the blades into place. The fine print in the directions tell you that it is part of the anti-jam mechanism. It's not startling or even disconcerting to me or my wife. We didn't blink an eye. I couldn't scare my children by turning it on. It just makes a bit of a click when you turn it on. No biggie. Full disclosure here - ours is mounted to the bottom of a heavy, porcelain coated cast iron sink. Our sink may be better at handling the torque and may dampen the sound and vibration more than a thin stainless steel sink. Our sink weighs probably 75 pounds. A stainless steel sink weighs 7 pounds. A heavier sink can probably handle a garbage disposal operating under full load better than a flexible, lightweight sink. That's not why we got the sink but I think it's probably a benefit to damping sounds and vibrations.
If your garbage disposal is making a clicking or rattling sound, there may be some food particles that will not grind up inside. Remove power from disposer, reach into the sink hole with a pair of tongs and remove anything that is still down in the disposer. Test your disposer to be sure the noise is gone. If not continue troubleshooting your disposer issue (see below).
