Top Causes of Garbage Disposal Leaks

There are many reasons why garbage disposals leak, from incompatible plumbing fittings to improper installation. But the top causes of a leaking garbage disposal are generally loose sink flanges, damaged or detached drain line connections, and damaged internal seals. Be sure to routinely clean and service your garbage disposal by a licensed and certified and trusted plumber to prevent major issues such as these. More importantly, if you notice garbage disposal leakage, act fast, immediately in fact, because small water leak can quickly turn into a disaster.

Garbage Disposals That Leak from the Top

The most common cause for a garbage disposal that leaks from the top is a loose sink flange. Fortunately, this is a minor and quick fix, so long as you know what you are doing, or you hire a professional to do it for you. A sink flange is a component that connects the garbage disposal to the sink. Sometimes, the plumbers’ putty can wear away, causing the flange to become loose. To fix, loosen the bolts, add some more plumbers’ putty around the seal of the sink flange, and then tighten the bolts back up. If you see that there is plenty of putty, simply check that the bolts are tight enough, as this could be the overall cause of the loose flange.

Garbage Disposals That Leak from the Bottom

A damaged, cracked, or worn out internal seal is the common cause of a bottom-leaking garbage disposal. In this case, it means that the garbage disposal is the component that needs repaired. If the water is leaking from a crack on the outside of the garbage disposal, it cannot be repaired, and instead, the entire unit must be replaced. Sometimes, the disposal unit gets shifted around as a result of storing items underneath the sink. Check that is it properly aligned, and make any necessary adjustments to put it back into its place.

Garbage Disposals That Leak from the Sides

A side leak on a garbage disposal unit typically indications a poor or lost drain line connection. In many residential kitchen systems, it is common for a dishwasher to be connected to the garbage disposal via a drainpipe, which directs all the collected debris and dirty water out of the house after the dish washing cycle. In some cases, the metal clamp that keeps the drainpipe in place can come loose or detach if the screws and rubber gasket sealing the pipe loses adhesiveness. Check this metal clamp to see if this is what’s causing your garbage disposal to leak. Tighten them back up with a screwdriver, and then check to see that the actual hose to ensure it has not been torn or compromised in any way.

Garbage Disposal Maintenance

It is important to stay on top of routine maintenance when it comes to your home’s plumbing systems. After all, it is one of the most vital systems in a household. But typically, the garbage disposal is overlooked. On a routine basis, you should clean out the disposal to eliminate food and solid residues, sanitize it to eliminate bacteria and other contaminants, and most importantly, have it inspected and serviced by a licensed plumber when it starts to show signs of problems.

Garbage Disposal Leaks

There are many reasons why a garbage disposal might leak; however, the top two causes for garbage disposal leaks are a defective gasket or a defective flange. Take a look below to learn more about each, including how to fix them.

Leaky Gasket

When a rubber gasket gets old, or goes unused for a long period of time, it can dry up and develop a crack, which in turn leads to a leak in the gasket. It can also be caused by improper installation. But how do you know this is your problem? If the leak is coming from the top rim where the seal mounts to the flange, it could be caused by a leaky gasket.

To repair a leaking gasket, you will need to replace it with a new one. Visit your local home improvement store to purchase replacement garbage disposal gaskets. They are inexpensive, but just be sure to get the right kind. There are some garbage disposal units that require a special type of gasket. If in doubt, refer to your owners’ manual.

Leaky Flange

Another common cause for a leaking garbage disposal is a defective flange. A disposal flange can develop a leak if the plumbers’ putty dries up, or if the bolts that connect the flange to the sink comes loose. How do you know if this is your problem? If the leak is coming from the very upper portion of the unit, it could be a flange leak.

To repair a leaking flange, there are a few options depending on the cause of the leak. The unit may just need to be re-tightened from underneath the sink, or the flange itself will need to be replaced. In other causes, the unit might need to be removed so that the plumbers’ putty can be reapplied, or so the flange can be released and the garbage disposal can be rehung.
