How to Fix a Blocked Kitchen Sink Drain from Cooking oil Build-up
When cooking oil or fat cool down, they tend to become solid. Whilst the majority will flow into the main waste water pipe, over time a build up of food particles and solidified cooking oils, has the capacity to block your kitchen drain pipes.
A blocked kitchen sink, is a breading ground for bacteria, and research has shown that more bacteria thrive in your kitchen sink than in your toilet.

The service can be carried out from outside your home in most cases, and the high pressure drain cleaning nozzles cut away the debris quickly. Even if the blockage is caused by tree roots, sand or most solid materials.
Another advantage is that the debris is blasted away completely and the pipe is cleared as if it was a brand new pipe.
