Special Features
Every Hydroflo valve is fitted with a silence tube (inset 4) for exceptionally quiet after
flush filling.
A useful key (inset 5) is attached to the divertor allowing quick and simple removal
of the filter without any risk of damage.
The unique float stem (inset 6) is securely retained by the float arm, making it
impossible for the float to become detached once installed. The float height can be
simply adjusted whilst the float arm ratchet enables very precise final water level
adjustments to be made. Once set, the float level stays firmly in place.
With health and safety firmly in mind, Hydroflo valves boast two built in backflow
prevention devices. An air break above the silence tube and a special membrane
inside the head of the valve stop bacteria that may be present in the cistern from
entering and contaminating the mains supply. This makes the Hydroflo one of
the safest valves available.
The telescopic bottom inlet version extends from 203mm (8") – 292mm (111/2")
to fit most cisterns, providing an extremely convenient solution. When tightened,
the locking nut clamps firmly to the valve stem for secure height adjustment.
