Blocked Drains


If you run a commercial kitchen or are the owner of a restaurant then you may have experienced the misfortune of dealing with a blocked drain. Fats, oils and grease (otherwise known as FOG) can build up and solidify within your drains and pipework, causing blockages and potentially further damage to your waste water and sewerage system.

Maddison’s FOG facts:

  • Drain blockages account for over three quarters of sewer flooding incidents in the UK.
  • Detergent and bleach have an insignificant effect on clearing oils and grease as the chemicals become diluted in the sewer network.
  • Macerators exacerbate the problem, by grinding up food (including fats) and flushing it in to the drainage system, only to congeal and build up within pipes.
  • There are approximately 366,000 sewer blockages throughout the UK every year, nearly all of which are caused by FOG.
  • The average UK cost to customers of a blockage clearance by a private drain clearance company is £70 but can be much higher depending of the severity of the problem. This isn’t considering the loss of revenue if you are forced to close your establishment – which can be up to £1000’s in lost earnings.

Introducing Maddison’s Products of the Month – the Clover UltraFLOW Drain Doser and Zi-GEST enzyme drain maintainer formula. This grease-busting duo is your effective management of drain maintenance, to continually protect your kitchen waste water system.

“But how does it work?”

The UltraFLOW is a wall mounted automated dosing system which releases a perfectly measured amount of fat-digesting enzyme into your waste water system – which keeps your drains protected, around the clock.

“This sounds complicated…”

Getting yourself up and running with the UltraFlow is simple. The easy-to-install box is connected to both your supply of ZiGEST liquid and your drainage system - down the plug hole. You set the dosage and time you need to dispense the liquid (we recommend out of kitchen hours) and it’ll do all the work for you. We can set this up for you for a small fee. It is battery operated so no need to call out an electrician.

“I thought detergents don’t work on FOG?”

ZiGEST isn’t a detergent – it’s an enzyme which breaks down animal fats, proteins and starches, keeping your drain free of fatty build up and food residue. The formula is pH neutral so it’s safe to use within kitchen environments, drains and sewerage systems.

“This sounds expensive…”

The UltraFLOW system costs only £175, and a 5-litre bottle of ZiGEST is £23.50. If you compare this price to the cost of a call out, maintenance and covering lost earnings then it’s clear to see the system is an affordable way to protect yourself from the inconvenience and financial outlay of a blocked drain.
