Leaking enclosed cistern

[johnmcmullin]

My cistern is leaking where the central flush valve (not sure of correct terminology) connects via a pipe to the toilet.
Because the cistern is inside a tiled-in box, I can't see underneath of it, but, feeling with my hand, the leak seems to be coming from around the top of the connecting pipe where it enters the cistern. I can't feel a nut or washer on the bottom of the cistern so I'm wondering if it all should be sealed from inside the cistern. I've posted a picture.

I really want to fix it without dismantling the whole thing. I've attached a picture to help people understand what I'm talking about.

Many thanks,

John

You will need to cut an access to the front of the tile area. I see this all of the time. People want tiled bathrooms but do not think of the maintenance of the sanitary ware.

Post a picture of the front of the tiled cistern

That's what it looks like from the front. It's possible to get a spanner down beneath the cistern but you won't be able to see what you're doing at the same time. From the look of the first picture, I'd have thought that you could take the valve apart from above. I've got a plumber coming tomorrow.

Most concealed cisterns would have a large nut connecting the flush valve to the cistern, then there would be another compression fitting with another nut connecting the flush pipe to the flush valve so I'd be very surprised if yours wasn't the same.
