Rigid syphon

Hi just to confirm does this look like a rigid syphon. Not seen in person but doesn't look like it one of the ones that splits so can replace the diaghram. Thanks

I'm not familiar with that particular one, but it looks to me as if you would have to remove the whole siphon from the cistern to replace the diaphragm. Would that be a problem?

No it wouldn't would be best to replace with a Dudley 3 part one or just an adjustable height one.

Im looking at it. If put a Dudley in would I be able to remove the yellow pin to split it? As the front of the syphon looks close to the cistern.

I agree that looks a problem - it's unusually close to the front, and the Dudley pin component is quite long.n

As you can see this syphon easily comes apart for future replacement of the syphon washer by unscrewing from the downward flush pipe, thereby eliminating the pin problem. They can be purchased from Wolseley. Hope this helps.

Thanks are the viva syphons any good?

They look just as good as any (I haven't personally fitted that make). There are lots to choose from.
