I am trying to replace the siphon on ac lose-coupled WC. I have turned off the water supply via the gat valve, and unscrewed the 2 screws that help support the cistern to the wall. The WC has an older overflow connector that goes outside, and I can loosen that ok, the problem is: The wing nuts are so stiff and I am not sure how to get them out! I don't want to crack the pan or cistern! I thought wing nuts went through the bottom of the cistern and connected the cistern to the back of the pan. These ones connect to the back of the pan but don't seem to come through into the bottom of the cistern!?? How will I get them out easily and are the wing nuts supposed to be this way?!!! Thanks for help !!!
the wing nuts typically sit on a bracket on the bottom of the cistern and dont go through it.
If you are replacing the whole toilet dont even bother with these just rock it out from the wall after undoing the wall and floor fixings and disconnecting the cold feed. it is easier to cut through the plastic overflow if you arent re-using it.
If, amazingly you have a cistern that will actually fit the pan if you are just replacing the cistern, I suppose you will have to cut through the bolts under the pan. Try some wd40 and a good set of grippers first.
sorry my previous post was a bit confusing! Basically I want to replace the siphon in my WC as it is not flushing properley as the disahragm is worn. I just cannot undo the wing nuts as they are really stiff and rusty and just wondered how to ease this problem? Should I use WD40 ? What tools should I use to undo the wing nut? I am worried in case I crack the pan that's why I am asking for help here!!! Thanks all.
