Toilet syphon replacement

[stratplus]

The turbo 88 only seems to be available in 7.5-9.5". Tha current syphon measures 11" from top to bottom. Is this likely to work.

9.5L is 11 " from the bottom to the top/ overflow part

The 9.5 adjustable goes from 191-241mm. 275mm is 11". That link says the max it adjusts to is 241mm which I think is 9.5" not litres.

where are you measuring from bottom to water finished level?

if you want to wait till tomorrow i can measure one for you but 80% sure it will fit

In my experience of where I had to fit a lower Syphon, I find the normal water level is still achievable about the same. The 11" high syphons were well above the water line.
In fact, the lower syphon will begin to flush quicker and much easier when handle is pushed down because it now only requires a shorter lift of water inside the lower syphon to start the flush

I read the Dudley turbo 88 is 29.2cm high

Exactly that.
Doesn't matter how high the old syphon is as long as the water level is below the new syphons water line it'll be fine and different length c-links will make sure the handle can still settle roughly horizontal.

Snowhead measured a couple for me in a thread last year, here's his findings:

I've just measured a 9" as 10.3/4" maximum height including washer on the bottom to where the screw goes in.

From Dudleys website, bottom of page; Syphon, dual flush syphon, toilet siphon - Dudley Turbo 88.

254mm 10" part no.313879
That'll be 11.3/4" in real terms.

Ooops.

Just changed one of these today and fitted a Fluidmaster cistern kit to the cistern with flush lever.

The old one was knackered as the customer had adjusted and fettled with it over the years and finally managed to shear the part of the syphon that the linkage goes onto.

Fluidmaster dual flush kit with the cistern handle flush lever fitted no probs and all operates correctly and the flushes are more efficient than the previous setup.

Cheers,
