Residential Grease Trap

Introduction

Residential grease traps have become vital for modern homes as they provide efficient waste management. They are a plumbing device that captures fats, oils, and grease (FOG) from wastewater and prevents it from entering the sewer system. The unit retains the FOG while allowing the treated wastewater to flow into the municipal sewer line.

How does a Residential Grease Trap Work?

A grease trap works on the principle of buoyancy. FOG is lighter than water, and therefore it floats to the surface. A grease trap has two chambers – the inlet and outlet. In the inlet chamber, wastewater enters, and the FOG rises to the top. As the wastewater flows into the outlet chamber, the FOG floats to the top, where it collects. The treated wastewater then exits the trap through the outlet and enters the municipal sewer system.

Types of Residential Grease Traps

There are two types of residential grease traps – passive and automatic.

Passive Grease Traps

Passive grease traps are the most common type used in residential settings. Passive grease traps use gravity to separate FOG from wastewater. It is a simple system that does not require any electrical components. The trap is located under the sink or in the basement, and wastewater flows through the unit by gravity.

Automatic Grease Traps

Automatic grease traps are an advanced type of grease trap that uses a pump and sensor to remove FOG from wastewater. They are more expensive than passive grease traps, but they are very efficient in handling large amounts of grease. The unit is installed in the kitchen or basement, and the wastewater enters the trap through a pipe. The FOG is then pumped out of the trap automatically, leaving treated wastewater to enter the municipal sewer system.

Benefits of a Residential Grease Trap

The main advantage of having a residential grease trap is that it helps to prevent blockages in the sewer system. Without a grease trap, FOG can build up in the pipes, causing blockages and sewer backups. Sewage backups can result in costly repairs and health hazards. By capturing FOG, a residential grease trap reduces the amount of FOG entering the sewer system, preventing blockages and backups.

Another benefit of a residential grease trap is that it reduces odors in the kitchen. FOG that is not trapped can accumulate in the pipes, causing foul smells. By capturing FOG, a grease trap keeps the pipes clean and odor-free, making the kitchen a more pleasant place to be.

Cleaning and Maintenance

It is important to clean and maintain a residential grease trap to ensure it continues to function efficiently. The trap should be cleaned regularly, depending on the amount of FOG produced. Passive grease traps should be cleaned every 90 days, while automatic grease traps can go up to six months between cleanings.

To clean a grease trap, the FOG must be removed from the trap. The FOG can be disposed of in the trash, but in some cases, it can be recycled. After the FOG has been removed, the trap should be scrubbed clean with warm water and soap. The inlet and outlet pipes should also be cleaned to prevent blockages.

Conclusion

Overall, a residential grease trap is an essential device for modern homes. It is a simple, yet effective way to prevent blockages in the sewer system and reduce odors in the kitchen. By investing in a residential grease trap and following proper cleaning and maintenance procedures, homeowners can ensure that their plumbing system operates smoothly and efficiently.
