Grohe 0.82m WC Concealed Cistern

Neil Asked :

I have a height restriction of 1m for the toilet with a concealed cistern and a depth restriction of 200mm for the cistern. Will the Grohe WC Concealed Cistern 0.82m - 38422000 work with a back-to-wall toilet (Duravit #215009) and Skate Cosmopolitan flush plate 38732000 in the space available? Please could you tell me also what fixing kit I will need for the flush plate and whether I will need anything else other than the extension pipe 37489000.

Answered By QS Team

The 200mm depth will be enough as the cistern needs 140mm. This cistern is universal and, therefore, can be used with pans made by different manufacturers. Also, the plate comes with a frame, which is attached to the inspection shaft, which is a part of the cistern.

1. Does the cistern come completely assembled? 2. Does it overflow back into the toilet?

Answered By QS Team

The cistern 38422000 does come complete and ready to use. However, it does not include the flush pipe extension, which needs to be purchased additionally. The overflow is designed for the water to flow back to the toilet pan.

What is the maximum height of this cistern? I only have about 470mm in height available from the top to the flush pipe. The flush plate is on the front.

Based on the information you have provided, this cistern may not fit. It is, however, the shortest that Grohe offers.

John Asked :

Grohe WC Concealed Cistern - 38422000 I am unable to centre the cistern with my WC. I need to offset to the right by about 200mm. Would I be able to fit a flexible flush pipe to connect cistern to WC?

Answered By QS Team

Grohe doesn't manufacture a flexible flush pipe. You can use a generic one from a plumbers merchant but this will affect the flush velocity so it may not clear waste.
