A grease trap is a device that catches grease before it enters the wastewater system. They are an integral mechanism for sewers, as they ensure that water flows freely in pipes and minimizes chances of blockages. To help you better understand how this device works, the drain cleaning team at Allied Reddi-Rooter in Cincinnati, OH, has created an easy-to-read guide to grease traps.
What Is a Grease Trap?
Sometimes referred to as grease interceptors and converters, grease traps have been used for over a century. Today, they’re installed in restaurants, hotels, and schools to limit the amount of grease that makes it into the municipal sewage system. They are usually made from plastic, concrete, stainless steel, or cast iron, and can be installed above or below ground. Sometimes, they’re placed directly inside of a kitchen, and other times, they’re buried outside of the building.
How Does a Grease Trap Work?
Since animal fats and vegetable oils are more dense than water, they do not dissolve with the substance. The grease trap takes advantage of this fact by slowing the flow rate so that wastewater cools and separates into different layers. While the grease rises to the top and is trapped, the solids sink down to the bottom and the water is filtered out. These solids are usually stored in a strainer until being cleaned out by a grease trap and drain cleaning company. If not cleaned out, fats and oils will back up into the plumbing system, causing an overflow inside your building.
Most grease traps should be inspected every two to four weeks by a grease trap and drain cleaning company. To learn more about grease traps and why it’s so important to get them pumped on a regular basis, call Allied Reddi-Rooter at (513) 396-5300, or visit them online for an overview of services.
