Tank Installation

The optional Poly A30 is a backflow and back siphonage prevention device also known as an AB air gap. It protects incoming mains water from contaminants which may have entered the cold water storage tank for processes which are carried out at the point of use or from water that has been added to the tank that isn’t mains supplied.

It is ideal for use in industrial situations such as in dentist’s surgeries (bodily fluids) and bakeries (yeast) or where water is fed to animals (disease).

It protects against the highest level, fluid category 5 risk laid down by the Department of the Environment and WRAS (Water Regulations Advisory Scheme).

The package includes:

  • A raised chamber which fits to the lid area of the tank
  • Extended ball valve arm which replaces the arm supplied as standard with the tank
  • Fixing screws
  • J4 Insulation
  • Seal
