Disconnecting water supply to toilet

[phil_cardiff]

Argh! I have a leak between my cistern and the bowl when it flushes. I reckon it's the rubber washer between the cistern and the bowl. Can I get to it? Can I hell. I obviously need to take the cistern off the bowl but need to disconnect the water supply 1st. Unfortunately I can't get my wrench onto the nut, pictured below, as the pan is in the way. Any ideas? It's the top nut as the one underneath it is below the isolation valve (the little screw head).

Cheers guys, so what we're saying is a tap spanner on the metal nut and if that fails some small grips on the plastic nut right at the top?

Or turn the water off at the mains,then undo the lower nut.

Then whilst it's off move the service valve lower down,for the next time.

I did think of that but was concerned that it would spurt everywhere?

Well grips aren't happening, there's just no room to turn it, even if I can get purchase on the nut.

Wish I knew if my water supply was tank fed or not. I don't think it is but not too sure!

Cheers Ferg.

Turned off the water at the mains, undid the bottom nut, still couldn't prise the cistern from the bowl! All wingnuts were undone too. Decided to give up for today so put the toilet back together and the leak has stopped. It won't last though.

I think there's just enough room for a basin wrench. The bolt is 22mm though so I'll have to order one or wait until the plumber merchant is open on Monday. Then I need to go back to the plumber merchant to get the right size donut. Happy days.
