What Causes Greasy Pipes?


Pipe grease is caused by cooking oils that seep into your piping system via leaks or spills over time. These cooking oils are lightweight containing mostly glycerin and animal fats. So they will easily slip past seals in your plumbing system. When these oils reach your drain pipes, they will harden as they cool and create a grease buildup on the inside of the pipes. It is important to deal with this problem quickly because these greases can cause blockages in your piping system that are incredibly difficult to remove.

Grease buildup usually happens behind kitchen appliances, on the floor beneath them, and along walls where there is a lot of moisture as a result of condensation. Kitchen sinks are particularly prone to this problem because it is here where oils are most likely to leak out onto the counter top or floor below where it can easily splash out when water is running.


One of the most likely culprits for kitchen grease buildup is your refrigerator if you have one.
