High pressure ball valves are used to refill water storage tanks. The arm on the valve, combined with a float means the water level should never reach the inlet. All high pressure ball valves are constructed to BS1212 Part 1 or 2.

Part 2 valves are generally quieter in operation and offer better protection against backflow.

Please note that high pressure ball valves are not supplied with floats. These need to be purchased separately.

All ball valves should be installed to WRAS specifications and a sufficient overflow should also be provided on mains water supplied systems. Further information can be found on the WRAS website.
