Hello guys.
My Dual Flush Torbeck Opella cistern has an internal overflow. It is now necessary to change the bottom entry inlet valve.
Neighbours sometimes cause blockage in the drainage/manhole.
I now consider to convert the cistern to overflow externally.
How could I block off the internal overflow?. With a rubber bung of some sort?.
The photo show the hole is not totally round. Any ideas, please?
