What is a Grease Trap?

Grease Traps, also known as grease interceptors or fat traps, are easy-to-fit plumbing devices. They capture (or trap) cooking fats, oils and grease (FOGs) before they enter the central drainage system. Food service establishments such as takeaways and restaurants generate FOGs during day-to-day business. Usually, it happens when washing and cleaning utensils and equipment.

Stainless steel or similar is the robust material that makes passive grease traps. Additionally, they are an essential kitchen device which helps safely capture this waste product. Put simply, Grease Traps are one of the most cost-effective ways to trap FOGs. They are widely considered a must-have for all UK commercial kitchens.

Grease Traps Stop Drain Blockages

Did you know water companies in 2023 are more active than ever in tackling ‘fatbergs’ or public sewer blockages? In September 2023, Severn Trent Water announced they recruited 300 new staff to cope with drain blockages.

Every year, South West Water deals with 8500 blockages costing millions of pounds. Purchasing a passive or gravity-fed grease trap can help massively reduce FOGs entering your immediate drains and public sewers. Grease Traps only use water flow to separate FOGs. They are low-cost to buy and easy to maintain. Equally, they are also practically free to run, which is welcome news for many!

Do I need a Grease Trap?

You will require a grease trap or management system if you produce hot food commercially. Building regulations 2.21 Part H stipulate that ‘Drainage serving kitchens in commercial hot food premises should be fitted with a grease separator.. or other effective means of grease removal‘. Correctly sizing, installing and servicing a grease trap is therefore very important to be compliant. Also, to protect public sewers from blockages. The benefit of using a passive gravity grease trap is that no electricity is required. As such, they are often much cheaper to buy.

Different Types

Furthermore, an under sink commercial grease trap does not require expensive parts and servicing. It simply relies on the gravity flow of water. You’ll find everything you need at Grease Trap Store for a commercial kitchen grease trap interceptor. Please choose from our range of indoor under sink stainless steel models starting from 20 litres. Try our epoxy-coated grease traps if you require a more rugged, weatherproof outdoor fat trap. They are also suitable for underground. Prices start from as little as £140 + VAT with free UK next-day delivery.

Are Grease Traps More Important Than Ever?

Grease is becoming a huge problem. More people eat out than ever before, so more fat must be disposed of. But how does FOG become a problem? Well, FOGs are approximately 10-15% less dense than water, and once cooled, FOGs will begin to thicken and harden. It is at this point that it becomes a significant concern. At the time when you are pouring grease into the drainage system, it may seem trivial. After all, it’s likely to be hot liquid still. However, after a short cooling period, this liquid grease will solidify.

FOG’s and Grease Traps

As FOGs solidify, they line drain pipework and cause blockages. Blocked drains can quickly become a nightmare for businesses and the public alike. Drains can overflow, potentially damaging property. In addition, there is a significant environmental concern of contamination of local bodies of water. The fines are hefty if a business is found guilty of abusing public sewer systems or water supply. It also attracts substantial negative PR. Also, Grease traps help trap this grease and ensure FOGs do not become a problem.

Grease Interceptors

Grease interceptors, also known as fat traps and passive grease traps, are relatively simple devices. They serve a huge purpose. A simple, well-sized fat trap can save you time and money in the long run. Buying from Grease Trap Store guarantees you’ll receive excellent quality at an affordable price.

The grease trap will pay for itself multiple times over. Especially when compared to plumbing costs should a severe problem arise from a grease-related blockage or overflow. Shop for grease traps now for rapid next-day delivery!

Grease Trap Guidance & Tips

8 Grease Trap Steps To Consider

  1. Check your grease trap on a regular basis. Once a week is generally good, but if you can check more, we’d advise you to do so. Remember, also, to always keep a record of your cleaning operations.
  2. Empty your grease trap before it is full. The earlier the grease trap is emptied, the easier it is going to be to empty, not to mention clean it. Don’t let excess grease build up until the point where it is being discharged into the sewer.
  3. Depending on the size of the grease trap (and the size of your commercial kitchen), you may want to consider employing a trained contractor.
  4. Clean all grease traps in accordance with the manufacturer’s guidelines/recommendations.
  5. Once all the grease has been removed from the grease trap, it should be stored in a suitable container and ready for collection. A licensed waste contractor will dispose of the grease in a safe and correct manner. You have a responsibility and legal duty to maintain a record of waste transfer notes.
  6. Check your grease trap lid is secure along with any other components to protect against accidents.
  7. Once the grease trap is set up and operating, you should monitor activity. If there is minimal grease in the trap over a period of time, check that it has been installed correctly. You may have other appliances, for example, a dishwasher too close to the grease trap. The flow of water/detergent may prevent the trap from operating effectively.
  8. If you experience problems with your grease trap, you should always seek advice from the grease trap manufacturer, supplier or installer. We also supply a range of domestic fat traps starting from just £140, additionally with free next day delivery via our couriers.
