At Hank & Sons Plumbing, one of the most common home plumbing problems we encounter is clogged kitchen sinks. In most cases, homeowners are able to clear the clog on their own. However, clearing stubborn clogs may require the services of an experienced plumbing professional.

Kitchen sinks can become clogged for many reasons. Trying to pass too much material down the drain at one time is a major cause of kitchen sink clogs. Another is placing the wrong items down the drain.

While a common plumbing problem, kitchen sink clogs aren’t necessarily a minor one. Clogs can damage your pipes and cause corrosion. Backed up, overflowing kitchen sinks have the potential to cause significant damage to your home.


The good news is that most kitchen sink clogs can be prevented. One of the best ways to avoid kitchen sink clogs and prevent damage to your drains and pipes is to be careful about what you dispose of down your drains. Here are twenty things that should never be placed down a kitchen sink drain:
