Universal Flush Valve Toilet Repair Kit

Unfortunately, some of our cisterns are manufactured with the outlet spigot moulded in as part of the cistern body, and are used with a push fit flush pipe. In these cases, the Niagara pneumatic flushing valve that we use could only be replaced with another like for like Niagara flushing valve. If the cistern has a more conventional flushing valve fitted, connected to the cistern by a back nut, with a flush pipe connected by means of a cone ring and cap nut, then it would be possible to replace the existing flushing valve with other type of flushing valve.

Our current range of fully compliant Hydroflo inlet valves, come pre-fitted with a flow regulator, so no need for a flow restrictor. Our previous range were supplied with a flow restrictor, which needed to be removed for water pressures below 1.5 bar. As these inlet valves operate on an equilibrium principle, which uses the supply water pressure against itself to operate the valve they are suitable for use on water pressures between 0.1 bar and 14 bar.

If a Hydroflo inlet valve is not closing off, it may only need for the diaphragm washer and filter to be cleaned. Remove the large white nut attached to the float arm, This will give you access to the diaphragm washer, remove the washer, and clean with running water. To remove the filter, use the white key stored on top of the blue overhead discharge nozzle. This has a Bayonet fitting to help remove the filter unit. Clean the filter of any dirt and debris. Replace the cleaned filter and diaphragm washer, and re-assemble the unit
