Universal Syphon Toilet Repair Kit

Yes! The Turbo Edge is the only toilet syphon that will retrofit onto existing Dudley downlegs (including the Turbo 88 Adjustable and Fixed Height, S44R and S1-11 syphons).

A syphon can be used as an internal overflow device, as long as the spill over point of the syphon is below any other external hole within the cistern body, normally the lever hole.

To convert the Turbo Edge syphon to single flush mode, disconnect the lever and unlock the yellow snap pin from the syphon. Remove the top spillover section, the remove the main blue upleg body section. Remove the metal C link and washer to release the piston rod. Remove the piston assembly from the upleg body section. Replace the stepped plastic washer on the top of the piston rod with the single flush plastic washer stored on the rear of the body of the syphon. Reassemble piston to the upleg body section, replace the C link, refit the upleg body to the white downleg, refit the spillover section and lock in the yellow snap pin. Replace the lever assembly and reconnect to the C link.

To find the correct height of the required syphon for a cistern, measure the depth of the water level line, within the cistern, normally marked at the back of the cistern, and then add 1” or 25mm to this measurement. This will give you the height of the required syphon. (Cisterns fitted before 2001, would have an original syphon in them that would be approx. 1 ½” or 40mm taller than the current requirements).

When fitting a syphon to a close coupled toilet, you need to ensure that the threaded tail of the syphon is trimmed back, to ensure that the syphon flush is not throttled back, giving you a poor flush. We recommend that the tail is trimmed back to 2-3mm from the back nut.

A syphon is measured from the bottom flange of the threaded tail, to the spill over point of the syphon, this is the effective height of the syphon. When choosing a syphon the height stated will be the height to the spill over point and not the overall height of the syphon (i.e. an 8” syphon would be 8” to the spill over, whereas the overall height would be 10”)

The operation of the dual flush syphon, is to flush and release the lever to give you a full flush, and to flush and hold the lever down, to give you a reduced flush. By holding the lever down, this lifts up two washers (one small blue plastic and one small black rubber) that are located immediately below the metal C link. When these washers are lifted up, this allows air to enter the syphon and breaks the syphonic action, the water level in the cistern will drop to just below the top of the syphon body, therefore giving you a reduced flush.

A syphon will internally overflow when the water level within the cistern reaches the spillover point. The water will trickle over the spillover point, and run down the downleg of the syphon, and into the toilet bowl.

The Turbo Edge toilet syphon has a very easy to activate flushing mechanism that makes it easy to flush for the young, old and people with disabilities.

These are to reduce the flush volume of the syphon within the cistern. By removing the plugs you will reduce the volume of water supplied on the full flush. If no plugs are removed, the water in the cistern will drop to the bottom of the syphon body. If the bottom plug is removed, the water in the cistern will only drop to this level. If the top plug is removed, the water in the cistern will only drop to this level.

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
