Replacing cistern valve question.

They look like two entirely different parts. Why didn't you get the right new part?

Edit, back in August I managed to source the correct valve for mine from Bathroom Spare Parts.

I have no idea what the real one is. This is an adjustable one from Screwfix and the closest that I can find.

I think it is this...

Cool, if this doesn't work I'll get that.
Thanks.

Personally I wouldn't be risking fitting a potentially ill-fitting part that might leak/fail (especially as it is, I assume, a concealed cistern so you won't know if it has worked)! 

I would not expect to be cutting but I would expect it to be adjustable.  Did it not come with any instructions?

All are adjustable - I changed ours from the old floaty ball to something like above on both the loo and the cold water header. Start off by adjusting so the water cuts off early, then increase the adjustment until it fills to the right amount.

No it doesn't. This is a flush valve. The floaty bit turns off the inlet water flow . It's adjustable for  the amounts of water going down the pan on full or part flush . 

Did you get a donut and bolts ? 

As long as it fits height wise it will be fine. Plus it looks like a newer qr version so if it fails prematurely the working part twists off  

Instructions were indecipherable. However it's fitted and works ...which is surprising.

Flush with success 😀

Way braver than me. My dad (electrical engineer), would try anything DIY but always avoided anything to do with water - I guess that rubbed off on me.

I'm the complete opposite. With water I can see if there's a problem. With electricity you don't know until you're dead on the floor or the house is on fire.
