Flow Free Drainage Ltd takes care of commercial kitchen grease management problems. Grease management systems such as grease traps are designed to protect your drainage system from becoming blocked or clogged by fats, oils, and grease (FOG).

Regularly maintaining and managing your grease traps is essential to stop a build-up of FOG substances and causing blockages, which will lead to disruption for your business. A regular grease management plan will prevent future problems and mean that no inconvenient delays to your day-to-day operations are caused. Our team will create a custom grease management plan with you so you can schedule for whatever suits your business best.

When maintaining your grease traps, we will remove the FOG substance and give it a deep clean to ensure that your grease trap is emptied of FOG and can work at its optimal level. It also ensures that fire risks are greatly reduced and eliminates hygiene concerns in your kitchen. Having grease trap management will also prevent your grease trap from creating unpleasant smells that would put customers off.

If your grease trap is damaged, our experts will come and fix it for you. A damaged grease trap can become a threat to their environment. For example, if your grease trap is overflowing, there’s a chance that the grease can spill onto the kitchen floor, leading to someone slipping and seriously injuring themselves. The risk of grease fires is much higher with a broken grease trap; this risks employees and customers’ lives as well as causing extensive damage to your business.   

We are known and recommended all over the South East for grease management, grease trap repairs and maintenance, and overcoming drainage problems for kitchens. Our years of experience help us to work efficiently. We provide an emergency service that is 24/7, so you can be assured that your grease management issues can be resolved by us quickly.
