Fire Sprinkler Water Tank 

Fire Sprinkler Water Tanks, otherwise known as firefighting water storage tanks, are designed to safely store water to feed fire sprinkler systems or for on-site firefighting water storage. Our fire water tanks are available with or without Fluid Category 5 backflow prevention.

All our non-potable water tanks are suitable to be used as fire sprinkler water tanks.

Plastic Tanks For Fire Sprinkler Systems

Polyethene tanks, potable water tanks and cold water tanks have a distinct advantage over steel tanks as they will not rust and are very easy to maintain. Polyethene tanks are also very adaptable and can be fitted with numerous connection options to suit most installations. Our water supply tanks for automatic sprinkler systems come in a wide range of tank sizes depending on the volume of water that is required.

Additional Equipment for Fire Sprinkler Water Tanks

Fire fighting sprinkler tanks will often require some or all of the following depending on the specification requirements similar to drinking water tanks. These are priced upon application.

  • Taps and inlet valves.
  • Cat & mouse or electronic device to show the level of water in the tank.
  • BSRT fire fittings including couplings, adaptors, blank caps, flange adaptors and washers in 2 ½”, 4” and 5” variants.
  • Side access hatch for access to the tank for maintenance work
  • Raised AB airgap for CAT5 compliance side spill over weir and cowl.

Fluid Category 5 AB Air Gap Break Tanks  

In some instances, these plastic water tanks will have to be Fluid Category 5 to comply with the requirements of installation and use of cold water storage cisterns and sectional tanks connected to the public water supply (Water Fittings) Regulations 1999. 

Enduramaxx’s range of Insulated Water Tanks is designed for use where temperature regulation is key and the prevention of overheating or freezing of liquids paramount. For Insulation Performance Information click here
