Flush valve replacement.

[RayW]

Does anyone recognise this flush valve? It's broken and tends to let water pass ...

I have got the same toilet in my garage and was from B&Q

Looks very cheap and nasty. I have replaced relatively similar-looking mechanisms because they were not working. You don't have to stick with the same make and model flush valve, you know.

Save yourself the grief mate , bin both valves and swap to Fluidmaster ( screwfix sell them )
Job done.
