Flomasta fill valve bottom entry with brass shank, v 1.1
Looks great but the instructions say the cistern thickness at the bottom mounting point must be min 8.5mm. Just a diagram - doesn't say why.
My cistern is a concealed one made of polythene or something like it, and is only 5mm thick.
Will be it be OK, do you think? What's the reason it says this and what is the nature of the risk if I fit it anyway? Might it leak? Seems unlikely.
Can anyone advise?
