2 Questions: Basin brackets and 'Unusual' WC

[WaterTight]

Unos :-

Seems like these type of basin brackets are usually used with makeshift packing of anything to hand between bracket and basin to try and get it to sit upright because basin usually wants to hang forward a bit. Is there a better less bodgey way to get these to work properly and hold basin tight and flat to wall? Got one that needs rehanging because silicone and makeshift packing could no longer hold it back and it now sits a bit forward. Seems a common prob from ones I've seen.

Dos :-

This WC is leaking when flushed (see green slime.) Not seen one like this before. Apparently someone put in new syphon and inlet and won't come back now it leaks. Would it have needed a custom close couple kit washer/plate instead of standard one it looks like he used or has he just not lined it up correctly/overtightened/generally mucked it up? How does it seal/flush between cistern and pan within that white plastic joining set-up?

Thanks

WC is a twyfords. If it is leaking where the plastic bit goes in the back of the pan there is a rubber flushpipe connector in there. Change it. The donut was a foam one.

If your struggling with the basin, try a bit of rapid set tile adhesive.
as for the bog...

on those twyford pans use some plumber mate as well as the flush plug
