Warranty - The average industry warranty on a garbage disposal is one year; however, it is not uncommon to see manufacturers’ warranties that can extend up to ten years. As a general rule of thumb, the more comprehensive and longer a warranty is, the more confidence the manufacturer has in the product they have made, but this is not always the case, so it is still important to do your homework.
The metal sink flange that sits directly inside the sink drain is typically sealed around the top with plumber’s putty (a clay-like sealant) and then secured from under the sink with bolts. If the plumber’s putty deteriorates, or the bolts loosen, the flange can no longer form a watertight seal between the sink drain and the disposal—which could cause a leak at the top of the unit.
Garbage disposals help us get rid of food waste, so it’s not surprising that the appliance may be susceptible to gross smells. A capful of bleach or grinding up citrus peels can help eliminate any foul odors coming from your garbage disposal. However, if nothing seems to help your appliance in the smell department, it may be catching food particles within its crevices. We recommend disassembling your garbage disposal to clean it, or replacing it if it’s old.
Reattach the electrical wires. Unscrew the faceplate on the underside of the new unit. Match the colored wires on the power supply to those in the disposal’s electric housing and connect them using plastic wire nuts. Slip the copper grounding wire over the green screw at the far edge of the compartment. Replace the cover and tighten the screws.
Flange: The flange is the uppermost portion of the garbage disposal, where the disposal and the sink drain meet. The flange can develop a leak for a variety of reasons. Check that all the mounting bolts, typically there are three, are tight enough. Snug the bolts up with a wrench if you see water dripping from any of the bolts, being careful not to overtighten the bolts.A second reason the flange may leak is if the seal, made of “plumber’s putty,” has failed. You will need to loosen the retaining bolts until you can see a gap around the flange. Force enough new putty in the gap, between the flange and the drain pipe, to fill in all the space. Tighten the retaining bolts.
If water is leaking from the disposal it more than likely needs a seal replaced but also could be a more serious problem. A leak can occur at the rings that are installed around the sink’s drain hole, called the sink flange. In that case, it can either be that the rings need to be tightened or that the plumber’s putty is faulty and needs to be reapplied correctly.
Look for a jam. Something too tough to grind, such as a piece of glass, could be jamming the motor. Turn off the power and water, then unplug the disposal. (If it’s hardwired, turn off the breaker.) Remove the rubber baffle inside the drain-most just lift out-and shine a flashlight into the hole. Fish out the obstruction with a pair of tongs or needle-nose pliers.
Whether you repaired or replaced the leaking garbage disposal, test for any missed problem spots. Wipe the unit dry with a clean cloth, then unplug the sink drain (if plugged) and pour a few cups of dyed water into the drain once more. Use a flashlight to inspect the entire unit. If you don’t observe a leak, turn on the power to the disposal from your breaker box and plug in the disposal at the wall outlet.
Next, you’ll connect the wires that you disconnected from the old disposer, to the new disposer. If this isn’t a replacement project, and you’re adding a new disposer where you didn’t have one before, you’ll first need to call an electrician to run the proper wires and a wall switch to the unit. For our project, the electrical wires and switch were already in place.
The garbage disposal in your kitchen sink is a convenient way to get rid of scraps and leftovers, but when a foreign object like a glass gets caught in it, it can jam the mechanism and stop it from working. Removing a glass from a garbage disposal involves removing any large pieces of glass; dislodging the glass by inserting a wrench or broom handle into the bottom or top of the disposal; vacuuming the disposal; resetting it; or if none of the other steps work, removing the disposal and shaking out all of the glass. Read the following steps to find out how to remove a glass from a garbage disposal.
Start by turning off and unplugging the garbage disposal. Next, you’ll need the wrench that came with your disposal. If you don’t have it, you can buy a replacement in a hardware store that sells your disposal brand. Find the hex-shaped opening at the bottom of the disposal unit. Turn the wrench clockwise to dislodge whatever’s blocking the flywheel. When the object dislodges, you’ll feel the flywheel start to turn easily. Reset the disposal and run cold water while quickly turning it on and off repeatedly.
Even though a leaking garbage disposal is a fairly simple fix, there can be a few factors that can complicate the process somewhat. For example, there are a few different places within the connection system that may spring a leak, so often the hardest part of fixing a leaking garbage disposal is trying to determine where the leak is coming from.Aside from the obvious connections, possible areas for leaks include water inlets and outlets as well as rings and seals.
To be prepared, measure the distance from the outlet to the top of each disposal before you remove the old unit. If the new unit’s outlet is lower, you must also lower the tee that the discharge pipe connects to. Loosen the two nuts that connect the tee to the tailpiece above and the trap below. Try lowering the tee to see if the tailpiece is long enough. If it’s not, you’ll have to replace it with one that’s slightly longer.
