For restaurants small and big, a grease trap is an important part of the plumbing system. With the amount of grease and fats that go down the drain, a lot of harm could be done to the plumbing of your building as well as affecting the city’s public sewer system. This is why you will find legislation requiring grease traps to be installed. For the most part, a grease trap will be maintenance free, having no moving parts, but they do need to be emptied fairly frequently depending on the size of the trap and the amount of grease that your business generates.
It is very important to have a grease trap that can handle the load put on it by your use. If it is too small, it could leak grease into the public system. On the other hand, if it is too large, hydrogen sulfide gas could be generated. This gas could then convert to hydrochloric acid that will damage metal and concrete.
