Villeroy & Boch Subway Back To Wall Close Coupled Pan & Cistern

[ILK]

Hi,

Would someone be able to advise me on the fitting of a Villeroy & Boch Subway Back To Wall Close Coupled Pan & Cistern?

I have fitted several Close Coupled BTW WC's before and all have involved securing the cistern to the wall. The V&B BTW cistern does not have any holes to fix the cistern to the wall. On closer inspection V&B market the WC as 'Floor Standing, Back to Wall' and recommend that there is a gap of 10mm between the wall and the WC/Cistern. I can't get my head round the reason for this 10mm gap. The cistern does fit nicely and securely to the WC but why a gap? It kind of defeats the true meaning of the term 'Back to Wall'.

Has anyone out there experienced this same issue or has an explanation? V&B don't seem to have a technical help line like most of the british brands so thought I would try this forum to seek an explanation. The V&B article code for the WC is 6610.10 and for the cistern it is 7723.11.

Many Thanks in anticipation of an explanation.

Ian.

As its a close coupled pan I suspect there are several likely reasons for the gap.
1st your floor may not be perfectly perpendicular to the wall fixing the cistern too the wall would potentially put undue strain on the ceramic
2nd as condensation often forms on the ceramic of the cistern due to the initialy colder temperature of the stored cold water compared to the warm and humid room. Leaving the gap allows the condensation to form and evaporate off without soaking your wall.

I habe fitted a lot of these.
just put a couple of spots of silicone behind the cistern, this will stop it from rattling against the wall.
most European cisterns are not fitted to the wall.
