What type of toilet system is this?

Thanks. Would I need to replace the inlet valve to do that?

Yep I've cleaned around the bottom where the seal goes - even when it closes off properly there's a very faint trickle all the time so it's not perfectly sealing.

Thanks for your help. Appreciated.

The inlet valve will have an adjuster but tbh I can`t see where it is in the photos, pretty sure somebody here will know.

Hi guys! Sorry to revive an old thread.

So the situation hasn’t improved much even with the flush valves being replaced. I’ve asked two plumbers who think it’s because of small lime scale deposits coming off and not allowing it to seal. They haven’t mentioned replacing the inlets.

Is there another system I could explore replacing these with that don't have these issues? If so what would they be? I can then ask my Plumber for pricing. It’s getting super annoying as 2ish times out of 10 it’ll experience this problem and I have to remove the shelving to gain access to the cistern to sort it.

Thanks for your help,
Dan

I've been out to a very similar situation, it was a Grohe cistern and the flush valve was passing. I can't say it was the same design though as it was a good few years ago..
The one I saw needed a different cistern to change the brand of the flush because the fitting at the bottom where the flush valve sits was not standard and the underside was moulded with the plastic cistern - so couldn't fit any other flush valve in there.
If your flush pipe is a standard size you could just replace the whole cistern with one from most plumbers favoured brand - Fluidmaster.
