Alison Asked :
Hi I havent' received a response to my query from a couple of days ago - please could you respond. I am asking whether this wall hung pan QS-V43395 is compatible with this cistern QS-V39530

Answered By QS Team :
For Duravit Darling New pan we recommend a frame and cistern and not just the cistern on it’s own. Therefore this will be 111.383.00.5 For 111.383.00.5 -- Refer this url Alternatively you can use Duravit DuraSystem Standard Toilet Frame Refer this url

Natalie Asked :
I see on the data sheet for the Geberit QS-V39530 that the height of the unit once installed is 108cm from the floor. I am wondering if this is a fixed height as I would like our boxing in to be shorter than this. Can the black flush pipe be adjusted to make the unit closer to the pan and therefore reduce the overall floor the top of boxing in height?

Answered By QS Team :
Sorry for the delay responding, the flush pipe to be reduced by 8.5cm as per technical drawing of the cistern. You Can Download the Product details and Technical drawing PDF from the link below.

Alan Asked :
I have several of these units installed at place of work and one of the cistern water continually flows how can i adjust this

Answered By QS Team :

There can be two main reasons for water to be running into your WC, both of these problems can usually be determined with on simple test and remedied by serving the correct valve or seal. You can watch the video link here: https://www.youtube.com/watch?v=9D4Fhcq8PLo

Water isolation test:

  • Turn off the supply of water to your WC, if you have a concealed cistern there should be an internal isolation tap inside your cistern which only cuts off the water to the toilet.
  • Leave for 15-20 minutes and check to see if water is still running into the pan.

If water still runs into pan:
Water is escaping underneath the flush valve even though the valve is closed.

  • It is most likely that the flush valve seal has become compromised, remove the flush valve (the valve in the centre of the cistern) and check the bottom for the seal.
  • If the seal has perished cleaned, replace with product code: 816.418.00.1
  • Check that the basket seal is clean and re-seat the basket

If the water stops running into the pan:
The cistern does not know when to stop filling, so it fills up too much and the water trickles over the overflow pipe.

  • It is most likely that the fill valve seal has become compromised, remove the fill valve (the valve at the side of the cistern) and check the blue arm for the seal inside.
  • If the seal cannot cleaned, replace with the correct product code for a side fill valve: 240.771.00.1
