I recently fitted Dudley turbo 88 siphons to all three of our toilets. The
short flush worked perfectly for the two upstairs toilets however the
downstairs cistern emptied fully every time no matter what.
I inspected all three and the only difference I could see was that the top of
the C link on the downstairs (faulty) siphon leaned away from the handle
whereas the top of the upstairs C links were vertical or leaning towards the
handle.
Therefore on the downstairs siphon I reattached the C link onto the next to
last hole rather than the last hole on the handle arm so that the top of the C
link leaned towards the handle.
This seems to have solved the problem. The short flush now works most of the
time although it helps to turn the handle quickly.
I hope this is of use to everyone.
