Finding replacement chain pull toilet syphon

[meb97me]

We've got an old overhead chain pull cistern on our bathroom toilet. Ever since we've moved in it's always needed several pulls on the chain in order for it to flush. I'd like to replace/refurbish it but i'm struggling to identify the make or a suitable alternative. Does anyone have any ideas on a make or where to try. The usual plumbing places local to me have had no luck and neither has online searches so far

Here's some pics

Thanks

Pull it apart first and see what you're left with...it might be a load of scrap.
All it probably needs is a diaphragm and they're available in various sizes or you roll your own.

If you can get the plunger out you can "just" cut a new diaphragm from a piece of Damp Proof Membrane ( or a fertilizer bag )

Iirc some of these are 1.25” round type syphons, however some have a syphon reducer. You can still purchase high level cisterns, or convert to low level depending how your wc pan is setup.

As it's our only upstairs toilet i was hoping to be able to find a replacement/parts in advance rather than dismantle it/investigate and be without a flushing toilet as i wouldn't be popular in our house

Give us a pic of the cistern underside, if you can.....it could be awkward releasing the syphon unless there’s some sort of conventional nut.

That thing was probably the original installation when the place was built, wooden box lined with lead, I'd say it's easily 100 years old, so can safely say it is probably well past it's best. I'd seriously consider replacing the entire cistern, before you get taken short, (literally) if/when it fails.

The last time I saw one of these, the syphon chamber was made from ceramic.....
All the others had a bloody great cast bell to set the syphon off - don’t know what they were called!

That's the one!
Used to be my job to replace the chain that had invariably rusted through and was lying in the bottom of the cistern.

That's what buckets are for fill a bucket and use that to flush until the unit is fixed.

I'd seriously recommend that's either replaced or restored. All it will take is one slight leak in the lead liner and that could come crashing down, lovely period feature mind you and would be lovely restored.

They do look good restored
