BSEN 13280:2001. If required, grade 316 S/S bolts may be placed throughout the tank.

Additional components

5. Raised Float Valve Housing

Permits the float valve to be mounted at a higher level on the tank, therefore increasing the usable volume of water.

6. Tank Division

All buildings requiring un-interrupted water supply should install a divider in the tank. The divider allows one side of the tank to be drained down for maintenance, while water supply is maintained from the second segment of the tank.

7. Ladders

Where the tank height is greater than 1.5m, an internal and external ladder is recommended.

8. Condensation Trays: Available for every size tank if required. Condensation trays are supplied in sections and bonded into a single unit on site. A condensation tray can only be supplied with tanks that have an internally flanged base.

9. Connections: Our sales team will discuss various options available.

10. Side Access Hatch: A side access hatch is beneficial where height restrictions apply. It also permits access, if in the event of personnel getting into difficulties inside the tank, while carrying out maintenance work.
