Cat 5 Booster Sets & Water Tanks

Complete pump supplies have a wide range of CAT 5 Booster Sets for domestic and light commercial uses.


A CAT 5 water booster set is a type of booster pump system that is used to increase the pressure and flow of water for applications that involve Fluid Category 5 (CAT 5) water. CAT 5 water is water that is considered to be a serious health hazard because it contains pathogens, radioactive or very toxic substances. This type of water is often used in commercial settings, such as abattoirs, farm wash-down areas, and dental practices.


Our Domopac CAT 5 packaged water booster sets typically consist of a pump and a tank complete with an AB Type air gap. The pump is used to increase the pressure of the water, the tank stores the water, and the AB air gap prevents contaminated water from flowing back into the mains water supply. Compliant to to WRAS regulations 1999 and BSEN 13077:2008.


Since 1999 it has been illegal for commercial organisations to put a hosepipe directly onto a tap to wash down machinery or a vehicle. It is essential to incorporate a back flow prevention device to ensure no back flow and syphonage leading to contamination of the potable water supply by bacteria returning up the hose pipe into the mains water supply.


Applications for CAT 5 booster sets:

  • Bin wash down/Bin stores
  • Garden irrigation
  • Laboratories
  • Hygienic Rooms
  • Veterinary Surgeries
  • Bib taps
  • Multi-story window wash

When choosing a CAT 5 water booster set, it is important to consider the following factors:

  • The size of the application
  • The amount of water that will be needed
  • The water pressure and flow requirements

The sets can be provided with single or twin pump fixed or variable speed pumps. We can also offer a combined all in one CAT 5 Booster Set, the set is a free-standing unit enclosed in a 25mm insulated GRP Tank with a CAT 5 AB Air Gap.
