How a Grease Trap Works


A grease trap is used to trap grease that may enter the drain, before it can enter the city sewage system.  The grease trap is a very simply device. As we all know, grease will float on top of water. So by placing the entrance and exit holes in the correct place the water and grease can enter the trap at the top, but only the water can exit at the bottom. In this video you can see a demonstration of this process.
