Septic Grease Trap

Pouring grease down the sink is a bad habit. Fat, grease, and oily substances solidify in the cool temperatures of your pipes, and over time, they accumulate and stick to the walls of the tubes, which can lead to clogs. Cue the foul odors, backups, backflows, and general unpleasantness. Fortunately for all of us, septic grease traps block wax, oil, and other fatty substances from clogging up your drains. This post will discuss maintaining your septic grease trap to keep your plumbing in great shape!

What is a Septic Grease Trap?

A septic grease trap, or grease interceptor, is a device installed in the plumbing system responsible for trapping grease, fat, and other oily substances before entering the septic tank. This helps to prevent clogs and backups by keeping these substances out of your drains.

Grease traps aren’t complex, but their design innovatively uses fundamental physics and biology to separate materials to keep your whole system working well.

There are two main types of septic grease traps: passive and active. Passive grease traps rely on gravity to separate the grease and oil from the water, while active grease traps use a pump to force the water through a series of filters that trap the grease and oil.

How do Septic Grease Traps Work?

Remember from science class – water and oil don’t mix. This is because water is denser than oil, so the oil will always float to the top. Grease interceptors work by taking advantage of this property. Any grease trap, whether automated or manual, separates FOG (fat, oil, and grease) from wastewater before it enters the drains. When wastewater goes into a grease trap, its flow slows down significantly so that solids sink to the bottom layer while wastewater stays in the middle and FOG rises to the top.

Water and waste enter the septic grease trap through an inlet pipe. The inlet pipe has a baffle, or curved wall, that forces the water and debris to slow down and enter the septic grease trap at a low velocity. This low velocity gives the solids time to settle at the bottom of the septic grease trap while oil and grease rise to the top and form a floating scum layer. In between the wastewater and scum layers is a clarified effluent layer that exits the septic grease trap through the outlet pipe.

The septic grease trap must be emptied regularly to remove the accumulated FOG. Grease traps should be cleaned out every three to six months, depending on the size of the septic grease trap and the amount of wastewater flowing through it. If a septic grease trap is not cleaned out regularly, it will become full of FOG and will not work correctly.

Why is it Important to Maintain Your Septic Grease Trap?

Maintaining your septic grease trap is necessary for several reasons. Septic grease traps are essential in keeping our sewage system running smoothly. When septic tanks and grease traps are not maintained, FOG can build up and cause clogs in the sewer lines.

  1. It helps to prevent clogs and backups by keeping grease and oil out of your septic system.
  2. It helps to protect your septic tank and leach field by preventing these substances from entering and clogging them.
  3. It can save you money in the long run by preventing costly repairs!

How Can You Maintain Your Septic Grease Trap?

You can do a few things to maintain your septic grease trap and keep it working correctly.

  1. Avoid pouring grease, oil, or fat down your drains. Just because a grease trap’s purpose is to trap grease, doesn’t mean you should dump oil down your drains with abandon.
  2. Carefully remove the grease tank cover so that you can access the notorious fats, oils, and greases.
  3. Slowly pour hot water on the fats, oils, and greases to liquefy them before scooping them out.
  4. You can also use enzymes or bacteria-based septic tank treatments to break down these materials.
  5. While septic grease traps are designed to be low maintenance, they need to be cleaned out regularly to prevent problems. Hiring a professional septic company to clean your septic grease trap is the best way to ensure it is done correctly and on schedule. A well-maintained septic trap will last for many years and provide your home or business with years of trouble-free service. Regular septic tank maintenance is the key to a properly functioning septic system.
