Clogged Pipes: What Not to Put Down Your Kitchen Drain

The inspiration for this post came from a pipe that we recently had to remove from one of our properties that was badly damaged due to improper items being disposed of down the drain (pictured). As you can see, the pipe was severely clogged due to things such as grease and coffee grinds being disposed of in the kitchen sink.
In a nutshell, the only things that should go down your kitchen sink drain are water and dish soap.
No Grease Please!
In general, we have found people feel that it is alright to dispose of grease down a kitchen drain, as long as they run the water. However, even if you flush water along with the grease, grease can still harden inside your pipes. What you may not know is that many pipes in San Francisco apartment buildings have several hundred feet to travel, so it is almost a certainty that any grease disposed of in your kitchen drain, regardless of whether you flush it down with water, will still harden along the inside of your pipes and cause slow and clogged drain issues later on down the pipe. (Pun intended!)
Other Items to Not Dispose of In Your Kitchen Drain
Additional items that are commonly found clogging a kitchen pipe include:
- Coffee Grinds
- dinner scraps/food
- hair
