Dear All.
I have been at this install for the best part of the day , I am not sure where I am going wrong with it.

The toiled pan is right up against the wall (see attached photo). When I tighten up the plastic nuts under the pan to fix the cistern to the pan the cistern gets pulled forward towards the pan and away from the wall leaving about an inch gap at the top. Spirit level confirms cistern is leaning forward (no photo of that for proof but I did check). Sorry no photo of the gap. Gap is only a few mm at the bottom of the cistern and gets larger as you go up (rough mock up illustration attached)

I have stripped it all down a couple of times (not moved the pan though as its now fixed to the floor, probably a bit premature doing that) and tried re-adjusting the big rubber doughnut washer and the plastic bolts that hold cistern and pan together but it keeps happening.

I haven’t screwed the pan to the wall as yet as I was afraid that I might damage the pottery or cause a leek as the cistern is pulled closer to the wall. There is not a lot of give in it when pan and cistern are fully tightened together (about 3mm to 5mm). A lot less than the void

Any and all help appreciated.

Cheers
James

Don't do the nuts up so tight.

As above,if you find it leaks,purchase a better quality rubber doughnut and use that,the nuts do not have to be that tight ,just holding the pan and cistern onto the doughnut to seal

Thanks for the help Scruff and White Pan Man
Unfortunately I did try that but I get leeks from the holes that the cistern fixings go through unless they are sufficiently tight which in my case is so tight that the cistern gets pulled forward.

Should there be washers on the plastic threaded bolts before the plastic nut goes on (none were supplied) There are rubber washers on the top of the fittings (the part inside the cistern as seen in attached photo) but they don't seal unless nuts are overly tight.

If I was to silicon the underside of the rubber washer on the fixing bolts then tighten up and leave it till silicon sets making a permanent seal allowing me to than leave the nuts a little looser be seen as an absolute bodge (not something I would normally consider but getting frustrated with it)

To make matters worse I now have a slow release of water down the pan from the dual valve
probably caused by me messing about with it so much. This causes the filler valve (float valve) to run continuously any ideas on that issue also appreciated.

The bolts go through the cistern with the washers on the inside as shown.

The should be a nut on the outside holding it.

The leak is probably just a bit of grit on the washer, take the siphon out and clean it

Sorry for the delay getting back about this, its all fixed now.
As suggested the foam doughnut washer that seals the cistern to the pan was the issue.
It kept slipping out of position as the cistern was tightened to the pan.
This caused the doughnut washer to become malformed as more pressure was added when the plastic bolts we tighten. In essence the doughnut became thicker at the back and thinner at front creating a wedge style fitting.
This is what caused the cistern to tip forward the more the plastic bolts we tightened.

It was my lack of experience in these things that was at fault.

To fix the issue I just pressed the doughnut down over the threaded pipe as flat as it would go, held it for a minute then quickly flipped the cistern over and placed it onto the pan and started tightening up the nuts to hold the pan and cistern together before the doughnut had a chance to return to its original shape.
I wish I had taken some photos to post along with this but hind sights a wonderful thing.

Big thanks to all who helped and if my woes help another then its not been all bad.

If you come across this post looking for info on a toilet install than please have a look at this first.

Had I done so my job may have been swifter and easier.

To clarify my problem I have pinched an image form the above posting (thanks to the original poster for it and apologies for not asking before “borrowing it”)
