Reasons Why Restaurant Grease Trap Cleaning is Imperative

A grease trap is an important component, which is installed under the kitchen restaurant to prevent oil, fat, and grease that is flushed into the drainage system from entering the sewer lines. These traps segregate the oil and grease from solid waste and water. As oil is light, in weight, it stays on the top and solid waste sinks to the bottom of the trap. Water that flows in between these two layers is flushed into the sewer lines but when the top layers are solidified, water is blocked. This eventually results in sewage backup in kitchens drains, which can be very messy.

It is nearly impossible for a commercial kitchen to work in full swing when the grease traps and drains are blocked. Proper drainage is essential for kitchen sinks and dishwashers to function appropriately. You can prevent restaurant plumbing issues by regular cleaning and maintenance of grease traps.

Why Grease Trap Cleaning is Essential for All Restaurants?

Prevents Foul Odor

Grease interceptor system prevents FOG from entering the sewer lines by proper segregation of sewage water. In due course of time, the residual grease tends to accumulate and stick to the walls of the trap. This can happen even if the trap is pumped regularly. The solidified grease blocks the kitchen drains and causes backups and foul odor. It also leaches the FOG into the sewer lines, which can block the main pipelines. Therefore, in order to prevent clogging of grease traps and ensuing foul odor, these interceptors must be cleaned regularly.

Clogged pipeline

Grease traps function consistently in a busy commercial kitchen by collecting FOG and allowing the solid waste to settle below the tank. However, the grease needs to be scraped off the walls of the tank, washed, and cleaned regularly to prevent clogging of sewage pipelines and filthy backups in the kitchen sinks. Overflows and backups in the kitchen can lead to expensive damage and loss of business which can be avoided by emptying these traps frequently.

Costly replacements

In due course of time, the oil, grease, and solid food particles that are collected in the grease interceptors begin to release harmful sulphuric acid, which can be extremely toxic for both humans and animals. The powerful acid, which is released from the waste collected in these traps slowly, begin to damage the inner walls of these interceptors. It even has the ability to destroy the steel walls of these traps. The replacements of these traps are relatively expensive which explains why it is so important to clean these kitchen traps.

Different companies provide different services, therefore you need to understand the demands of your restaurant and then choose wisely. Although grease interceptors need to be emptied and cleaned every 90 days, it must be cleaned more frequently if you own a busy restaurant.
