GRP Break Tanks

Ensure Zero Backflow with a break tank

GRP Break Tanks Ensure Zero Backflow

Nicholson Plastics Break Tanks are manufactured from glass reinforced fibre (GRP) A break tank refers to closed tanks with an air gap, preventing any backflow of water into the system. This is to prevent any contamination into the mains supply of potable water.

Prevent contamination and create pressure zones

  • Having an air lock ensures no water is able to back flow into the mains supply eliminating any risk of contamination of main potable water storage.
  • Break tanks can be used as transitional tanks, which service as a divide for boosting systems into a number of controllable pressure zones.
  • Nicholsons provide insulated potable water storage tanks for domestic and commercial uses. All our tanks are manufactured from GRP glass reinforced plastic which is one of the strongest materials on the market.
