Toilet Flush Button Stuck

[andytbker]

Hi,
For a while now one of my flush buttons on the toilet has started sticking down and so it just continues flushing. I can get it to pop back up by wiggling it around a bit but this is starting to get quite annoying.
Is there any part of the system I could easily replace myself that would fix this?

Best to replace the flush as I’ve never seen that type/make before

I normally fit fluidmaster

 

[andytbker]

Thanks, I've been looking at replacement flushes like fluidmaster but they all look completely different to mine, will they still fit?

 

[ShaunCorbs]

Yes only difference is some are 2” others are 1.5” but the fluidmaster normally comes with an adapter for both

Is that a combined fill and flush valve? If thats the case you will need to change both.

I don't know, can you tell from these photos?

I have never seen that sort of arrangement before. That is a flapper valve. If you disconnect the small tube from the valve in the middle will the toilet still fill? Just check the small tube doesn't have any holes in it. It looks like when the fill valve fills the cistern the tube may help to close the flush and lift the buttons back up.

Thank you, yes that definitely looks like mine, although I can't find anyone actually selling them or one like it?.
Should I disconnect the one end of that tube and just try flushing again to test it?

You could disconnect the tube, if the cistern fills ok you could just replace the flush valve. But I think I would replace both as you could well be in the same boat in the future. If you do, make sure you buy a fill valve with a brass tail.

It’s a trap primer found mostly on the American side let’s water through after a flush

Thank you, could you point me in the direction of someone supplying them, I can't see anything the same on screwfix

 

[ShaunCorbs]

You shouldn’t need one so just any push button siphon should do etc

 

[andytbker]

So I would just connect the new siphon back up to the thing on the left? Or is that not necessary at all?

 

[ShaunCorbs]

You would need to replace both fill and flush valves

 

[andytbker]

So would this do the job?: Fluidmaster Button Cable Dual-Flush & Bottom Inlet - https://www.NoLinkingToThis/p/fluidmaster-button-cable-dual-flush-bottom-inlet/58353

 

[andytbker]

Would really appreciate someone letting me know if the one I've picked above would be suitable?

 

[ShaunCorbs]

Yep that will be fine

 

[andytbker]

Thank you

Hi all,
I've bought the new part and started dismantling the toilet. I've removed both the plastic nuts holding the cistern in place. But how do I undo the inlet valve? I've undone the plastic nut but the cistern will still not come loose. I've tried undoing the top metal nut but when I turn anti-clockwise it turns the whole metal assembly and lower metal nut too. Should I be holding the lower nut with grippers before undoing the upper nut?
Attached is a photo of the assembly.
