Gustavsberg TP-10 Membrane replacement

Our Gustavsberg 315 T4 toilet started leaking and after disassembly I found out that it was the membrane in the inlet valve. This is my own design thats worked for me. The membrane is slightly smaller towards the middle and I placed it in the inlet valve with the flat side up. I also upped the flow for my filament a little to make sure the membrane was watertight.
