No other pieces are available but yes you can get a similar type of different material plastic pipes from professional hardware shop.They deals in this plastic piper.
Also if you get bigger pipe from required size then you can get the extra size cut from local plumbers who mostly deals in this types of jobs.
thanks.

I too have had this problem. No matter how i change the settings ..sooner or later the toilet starts to flow continually getting worse and worse. I have had plummers and friends etc see if they can make it stop and it is no better. I am very disapointed with it and will never ever buy Duravit again. I tried contacting them for help and got nowhere. Bad design. Waste of money.. I should have stuck with the old ball-**** system at B&Q.

You need a new fill valve,Get Fluidmaster style.That is if you have the old ball type.

We find toilet flappers the main reason there is septic backups(leaking flappers)
Good luck.

Depends on the model you have. Try the back of the unit or under the supply panel on the left side.

Contact Duravit or its distributor to request the manual.

Are you sure the flapper is dropping back down? Theflush handle may be sticking and holding the flapper valve up.

Remove and clean the flush valve and the flush valve seat(it is the flap that opens up to allow water to flush the toilet). Once the edges of the valve and the seat are cleaned, possibly with "0000" grit bulldog steel wool, it should not leak anymore. To make sure it is not leaking, once tank has refilled completely, put some food die in the tank. If, after 10-15 minutes, the water in the toilet bowl is colored, you have a leak from the flush valve. Replacing the flush valve is very easy - just bring the old one with you to the hardware/plumbing store and ask for a replacement. Blessings and good luck!!

Google the company they will have price and stockist in you area

I have the same problem - do you ever find somewhere to buy one?

pull the control section from the cistern. Normally they are only press plastic tabs and the whole unit lifts out.
