If the disposal’s still leaking, loosen the mounting bolts and push the sink flange up until it’s slightly higher than the surface of the sink. Apply fresh plumber’s putty to the threshold between the flange and the sink. When you’ve applied enough, re-attach the unit by putting the bolts back and tightening. Wipe away excess putty that squeezed out. Finish re-installing by replacing the disposal unit on the mount. Turn the disposal back on and look for leaks.

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.


Most plumbing problems associated with holiday parties are caused by improper plumbing maintenance and overestimations of your plumbing system’s abilities. Although it’s best if you have a professional plumber inspect your system before any large gathering, many plumbing problems can be prevented with a little knowledge and preparation before the big day. Remember, the best offense is a good defense. Schedule annual plumbing maintenance to keep your entire plumbing system healthy and efficient. Current problems will be addressed and future problems will be detected.
After watching this video, I decided I could replace my garbage disposer myself. Honestly, I think your site completely misrepresents how VERY difficult it is to hold up a 20+ pound disposal unit firmly up against the mounting hardware as you are literally crammed under your kitchen sink and then try and somehow get all three tabs to slide into place. I was very disappointed and, after 4 nights of trying and retrying, finally just called a plumber. Please don’t show anyone lifting something that is big and heavy and make it seems as light as a feather. Shame. Shame.

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.
Manufacturers’ warranties for garbage disposals range from one year through the lifetime of the unit. One of the best warranties in the industry is the one offered by WasteKing on all of their garbage disposals. Should your disposal system fail due to material defect or mechanical effort during the purchaser’s lifetime, WasteKing will replace the unit for free. This is compliance to the policies provided for by their lifetime warranty.
Installing a garbage disposal involves tapping into your home’s plumbing and electrical systems, and both systems need to be handled correctly to safely install your garbage disposal. Someone with a lot of experience can handle the job in 2 or 3 hours—or maybe even less. Attempting a garbage disposal installation without any training will likely take at least double the time required for a professional to install the garbage disposal.
With the garbage disposal shopping, I quickly learned that the big brands are Waste King and Sinkerator and that those were the two best places to start. After going over several models and two trips to two separate best buys (who, by the way, really need to amp up their customer service model) I cheated and had my mom choose one for me. Sue me. So she chose this particular brand, and wow—it works really well, I can’t believe how easy it makes my life. I can put bones, and tough food products down the disposal, and it makes cooking really simple. Go figure.

Modern garbage disposal units connect to dishwasher drainpipes.  This enables dishwashers to expel leftover food scraps and residue that would otherwise accumulate in the dishwasher unit.  A common source of leaks is the area where your dishwasher and garbage disposal connect.  These leaks most often occur when the hose’s clamp is not secure enough and when the dishwasher hose cracks.  To fix this issue, simply replace the cracked section of the hose or tighten the clamp.
