Grease Trap Essentials – A Guide To Proper Installation And Maintenance

Grease Trap Perth is an essential part of modern kitchens. They intercept and separate fats, oils, and grease (FOG) from wastewater before it enters sewage systems or septic tanks.

As wastewater flows into the trap, it slows down, allowing the less dense FOG to rise while solids settle to the bottom. This separation helps prevent clogged drains and sewer lines.

Grease traps are vital for preventing fats, oils, and grease (FOG) from flowing into sewer systems, where they can cause costly and dangerous clogs. They are required by law in many commercial kitchens, hotels, restaurants, food-processing establishments, and supermarkets, where large amounts of FOG can be generated.

Regularly cleaning grease traps prevents the accumulation of FOG, which is a primary source of sewer backups and foul odors. Additionally, it keeps wastewater flowing properly through drainage systems and reduces the risk of contamination to municipal water supplies. A regularly cleaned grease trap also ensures compliance with local plumbing codes and regulations.

Before starting the grease trap cleaning process, it is important to take proper safety precautions. Rubber gloves and a face mask or nose plug are recommended for protection from the fumes produced by degreasing chemicals. The grease trap should also be emptied before beginning the cleaning process, and all materials, including scraps and cleaning residue, should be disposed of by environmental regulations.

During the cleaning process, it is essential to use only chemical-free cleaners. The use of harsh detergents and solvents can cause the trapped FOG to separate from the rest of the wastewater, resulting in a less effective grease trap.

Once the grease trap is clean, it should be tested to make sure it is functioning properly and there are no blockages or leaks. It is also a good time to perform any necessary maintenance, such as sealing leaks or replacing baffles and gaskets.

While many municipalities set minimum and maximum grease trap cleaning frequencies, it is best to service your grease trap regularly to maintain a high-quality oil-to-water ratio. A dependable technician can help with a thorough cleaning, inspection, and repairs to keep your kitchen running smoothly and efficiently.


A grease trap is a plumbing device designed to intercept and separate oil and grease from wastewater before it enters sewage systems and septic tanks. This prevents the accumulation of FOG in these systems, which can lead to blockages and costly repairs. It also helps restaurants avoid environmental damage and comply with local regulations.

Choosing the right type and size of grease trap for your restaurant is an important step. There are many different models and sizes available, and the laws regarding placement vary by state. Be sure to consult with a manufacturing professional, as well as your local commercial kitchen regulations, to make the best choice for your business.

Once the grease trap is installed, it is important to make sure that it has a proper connection to the sewer line. A poorly connected grease trap can cause leaks and other problems, leading to expensive repair bills. To prevent this, always use a primer and cement for ABS piping or thread sealant for metal piping.

Grease traps must be cleaned regularly to keep them functioning properly. This process can be labor intensive, so it is important to gather the right tools before beginning. You will need a crowbar and wrench to remove the lid, as well as a large garbage can, trash can liners, and cleaning supplies like gloves, a steel pot scrubber, and dish soap.

To protect your hands and your environment, it is important to wear rubber gloves when handling the grease. It is also a good idea to wear a mask or nose plug to protect against odors while working. Additionally, it is a good idea to use a utility sink to wash your hands afterward.

A grease trap must be pumped out when it reaches about a quarter of its capacity. This will help to reduce foul odors, as well as ensure that the trap is doing its job by separating FOG from wastewater.

It is recommended that you use strainers or filters on your sinks and drains to help minimize the amount of solids that can make their way into your grease traps. Using these types of devices can also help to extend the lifespan of your traps by protecting them from debris that can clog them.


If you want to avoid costly grease trap clogs and keep your kitchen running smoothly, you must follow proper cleaning and maintenance procedures. This includes regularly removing and disposing of fats, oils, and greases (FOG) from your trap. Here are some important things to know about the cleaning process:

The First Steps

Locate your grease trap and remove the lid. Place a bucket underneath to catch any water or grease that spills during the removal process. It’s also a good idea to wear gloves during cleaning to protect your hands from bacteria and other harmful chemicals. You’ll also need a scraper and a high-quality grease trap cleaning solution.

Once you’ve gathered all the necessary tools and supplies, it’s time to start the cleanup process. It’s important to remember that it’s always best to clean your trap using cool water. Warm water causes grease to float to the top of your trap, making it harder to remove and scrape off.

After you’ve finished scrubbing and scraping your trap, it’s important to test it before putting it back together. If you see water flowing through easily, then your trap is ready for use!

Before reassembling your trap, it’s a good idea to take photographs or diagrams of the different parts to ensure you get them back in the right order. You’ll also need to check local regulations for guidelines on how to dispose of your grease and waste.

If you don’t have the time or energy to clean your grease trap, consider hiring a professional service provider. Professionals have the experience and equipment needed to efficiently and effectively clean your trap, ensuring it’s working properly. They’ll also be familiar with local regulations and compliance standards, which may affect your business.

Keep in mind, though, that while hiring a professional service may save you money in the long run, it can be more expensive upfront. Plus, you won’t have full control over their cleaning plans and may not be able to schedule services during busy hours. It’s also important to choose a company with the proper certifications and insurance coverage to guarantee their work.


Most homeowners are familiar with the concept of DIY home improvement projects. Depending on the scope of the project, however, some tasks are best left to the professionals. This is certainly true when it comes to installing and cleaning grease traps, which are essentially large plumbing devices that collect FOG before it enters sewage systems, water treatment plants, and septic tanks, where it can cause clogs and other costly problems.

The installation process is a crucial part of setting up your grease interceptor to function optimally. After the trap is in place and all of the inlet and outlet connections are made, it is important to test the system to ensure that it is operating as designed. Once the trap is in working order, a regular maintenance schedule should be implemented to keep fats, oils, and greases from building up.

Grease traps should be inspected and cleaned at least monthly or as needed. Once the grease level reaches 25% of its effective depth, or every three months (whichever comes first), it’s time to call in licensed septage haulers. Professional maintenance keeps your kitchen running smoothly and averts the risk of costly sewage backups, foul odors, and other unpleasant issues.

During the maintenance process, it’s recommended that you use a degreasing agent to break down any remaining grease build-up. It’s also important to make sure that all of the FOG is removed from the trap and disposed of properly. It is never acceptable to simply dump excess FOG down a drain. FOG will solidify in the pipes, creating clogs that can cause wastewater backups, foul odors, and damage to the pipes themselves.

When partnering with a company to perform grease trap maintenance, it’s important to choose one that uses a certified and trained crew. This will not only help to ensure the cleanliness and safety of your employees, but it will also improve the efficiency and effectiveness of the maintenance process by allowing for more thorough cleaning and inspection.

It’s also important to consult with a professional to determine the optimal grease trap maintenance frequency for your establishment. A quality provider will help you develop a scheduling system that meets your needs while maintaining compliance with local regulations. Failing to maintain your grease trap can result in clogs, sewer backups, and even fines.
