Hi people. Having a bit of a nightmare here. Trying to fix the toilet myself. It’s a closed coupled toilet. I replaced the valve and the flush for it but did a massive schoolboy error.. when I unscrews the cistern from the toilet the wing nuts fell, and there is zero access to them with taking the toilet out which I really don’t want to have to do because it has been there a very long time. Anyone got any ideas how I can secure the cistern back on to the toilet? I’ve uploaded a couple of pics. Thank you, Ryan.
