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 water shut off valve (the little screw head).
Expect you've done it by now but if you have'nt ....
I would turn the cold water off at the stopcock.
Close your isolation valve under the cistern....
Flush the toilet and scoop out the remaining water.
Then undo the lower nut on the isolation valve (pictured).... then you can undo the wing nuts on the base of the cistern ... the whole cistern can then be lifted clear of the supply pipe and pan.
You then have access to the large washer/doughnut that makes the seal between the pan and the cistern.
