Replacing part of a toilet cistern flush system - possible?

54and56

Hi all,

The bottom retainer piece of the flush system which the push button screws through the cistern lid into has shattered resulting in nothing happening when the button is pushed down. The rest of the system works fine and with the lid off the cistern the toile can be manually flushed.

Rather than replace the full flush mechanism which in my case will definitely have to be outsourced to a professional plumber I'm trying to find out if it's possible to just replace the top part of the flush mechanism which connects to the push button and activates the flush.

The piece inside the pink circle has broken away, see area circled in blue below.

I guess my question is whether or not the top section circled in green below can be retro fitted to the existing flush mechanism thus removing the need to do a full replacement of the flush system or does the full flush system need to be replaced?

Appreciate your thoughts and guidance.

Search the likes of Amazon for toilet syphon replacement kit until you find a similar one to yours.

This looks similar https://www.amazon.co.uk/Twyford-Optima-49-Toilet-Cistern/dp/B0B7RZQK9C/

Use that as a refence for the name of the product you are looking for parts for then search for the parts for it and the manual.

If it is the Twyford Optima 49 then here's the manual https://siamp.co.uk/wp-content/downloads/manuals/50_5498_01_LD.pdf which indicates you can swop out the whole main section.

If you are sure you don't need the button (assuming I picked the right syphon) then this seems your cheapest option https://www.amazon.co.uk/Monaco-Optima-Toilet-Cistern-Without/dp/B08YNY6S9S

Fairly sure you can change just the parts you want because the unit is adjustable for different sizes of toilet cistern.

That's amazingly helpful @The Continental Op

Looks like mine is indeed the Twyford Optima 49 and what I need to do is source a replacement "Stirrup" mechanism or the whole syphon kit and just swap over the Stirrup section.

This looks to be on the money - https://amzn.eu/d/7TqxBfw

Yep thats the one I thought looked a good deal. I'd consider changing just the bits you need as you sometimes find there are generic versions of brand name things that aren't exactly the same. If you are lucky you can change the whole top section but if not then try just changing the adjustable top section.

If you have to its really not a big deal to change the whole unit. Only tool you need is a decent pair of water pump pliers.

FYI I ended up unscrewing the entire installed Syphon unit from the base in the cistern and simply screwed in the replacement using the original base / pan gasket and it is working perfectly. I didn't think the replacement unit would screw into the original strainer without there being some dripping but it seems to have formed a tight seal with no dripping so all seems well that ends well. Thanks for your help as ever @The Continental Op
