Why Is My Garbage Disposal Leaking?

Garbage disposals are an incredible kitchen appliance, and they’ve made food waste cleanup much easier.  Unfortunately, like any machine, these appliances can start to encounter issues.  If you’ve noticed water leaking from your garbage disposal unit, it’s best to inspect and see if you can discern the source of the problem.  There are a few reasons why your garbage disposal might be leaking, and most of them can be fixed yourself.  A leaky garbage disposal can cause water damage to your home, so be sure to take care of the problem as soon as possible.  If you’re stuck wondering ‘why is my garbage disposal leaking?’ then we’ve got the answers and solutions you’re looking for.  You’re going to need to check under your sink for the source of the leak, so be sure this space is accessible before you start.


Worn or Damaged Seals / Worn out Rubber Gasket

The most common reason people experience leaking with their garbage disposal is due to worn-out seals.  These seals can deteriorate over time or may have food particles stuck in them.  Be sure to inspect the inside for any damages.  The rubber gasket ring at the top of the disposal unit may also be the problem.  Extended periods of dryness may cause the rubber to crack and develop a leak.  Thankfully, these are usually simple to replace and can potentially be done yourself.  Take the old gasket to a hardware store and they should be able to help you find matching replacement parts.


Loose Piping Leaking Water

There are a lot of connective pieces to a garbage disposal system; sometimes, these connections can loosen and allow water out.  Check the connector between your disposal and the drain pipe or dishwasher hose; if you see water leaking from the connectors, this is likely a problem of loose drain lines.  Use a wrench to tighten the connectors and see if that fixes the leak.


Your Sink Drain is Clogged

Another common reason why you may be experiencing a leaky garbage disposal is due to clogged drain pipes.  When the drainpipe is blocked, water can back up and overflow from your garbage disposal.  If this is the case, use a drain snake to help dislodge the blockage.  If that doesn’t work, try mixing baking soda and vinegar and pouring that down the drain, then follow with hot water.  Sometimes the drain line cannot be unclogged without professional help; if you’ve tried to DIY with no success, don’t hesitate to call a plumbing repair service.


The Garbage Disposal is Damaged

If your garbage disposal is particularly old, it may be the problem.  The outer housing can crack and allow for leaks.  You may also find the unit is leaking because there has been damage done to it.  Utensils accidentally dropped down the disposal or other such accidents can damage the disposal.  Be sure to inspect your garbage disposal unit for any signs of wear; if there are obvious cracks or other damages, you may need to replace the whole unit and these types of damages are difficult to repair.


A leaking garbage disposal can be a real hassle, and can cause water damage to cabinets and other parts of your home if not addressed.  If you find there’s leaks under your kitchen sink, always be sure to inspect the disposal drain and unit for possible causes.  If you’re unable to fix the problem yourself, don’t be afraid to call a plumbing repairs service.  We at Mainline Plumbing deal with garbage disposal leaks and drain problems regularly, and would be happy to lend our services to you.  Visit our website to learn more about our different plumbing repair options, or give us a call and we can get your problem solved quickly.
