If you run a commercial kitchen, you’re probably no stranger to unpleasant drain smells, slow sinks, or surprise plumbing bills. These issues often have one thing in common: fat, oil, and grease (FOG) buildup in your pipes.
Every time you wash pots, pans, and plates, traces of grease go down the drain. Over time, that grease cools, hardens, and sticks to the inside of your plumbing. This leads to blockages, odours, and expensive repairs.
Why FOG Is More Serious Than You Think
Grease isn’t just a nuisance. It’s a legal and environmental hazard.
Under the Water Industry Act 1991, it’s a criminal offence to discharge matter that interferes with public sewers. This includes grease and food waste.
Local water companies can fine businesses or pass on the cost of clearing blockages. In serious cases, this can mean thousands in damage and even temporary closure.
Common Signs You Have a Grease Problem
- Drain smells that won’t go away
- Sinks draining slowly
- Water backing up during busy periods
- Repeated callouts for blocked pipes
- Grease found in interceptors or traps during inspections
If any of these sound familiar, it’s time to act.

What’s the Best Way to Stop Grease Blocking Your Drains?
The most effective solution is installing a grease trap, a device that removes FOG from wastewater before it reaches your pipes.
But not all grease traps are created equal.
At Catercall, we recommend the Big Dipper. It’s a compact, automatic grease trap that actively removes grease with minimal effort from your staff.

- Automatically separates and collects grease
- Reduces odours with a sealed, hygienic design
- Fits easily under sinks in tight kitchens
- Cuts down on costly pump-outs and emergency callouts
- Keeps you compliant with UK drainage regulations
It even meets tough industry standards like ASME A112.14.3, so your kitchen stays up to code without the stress.
Say Goodbye to Grease Headaches
Don’t wait for a blocked pipe or a fine to take grease seriously. The Big Dipper gives you reliable, low-maintenance protection and peace of mind.

Frequently Asked Questions
Do I need a grease trap by law in the UK?
Yes. UK water companies require food businesses to manage FOG. Failure to do so can lead to fines or prosecution.
How often should a grease trap be cleaned?
With automatic systems like the Big Dipper, basic maintenance can be done daily by staff, avoiding the need for regular pump-outs.
Can I install a grease trap myself, or do I need a professional?
While some grease traps are simple to fit, we always recommend using a qualified plumber. A proper setup ensures the unit complies with water company standards and performs at its best from day one.
What size grease trap do I need for my kitchen?
The right size depends on your kitchen’s daily volume, sink setup, and local regulations. Catercall can help assess your needs and recommend the correct Big Dipper unit for your space and output.
