Bromley Date: December 8, 2020

Concealed cistern
Quite an expensive cistern but perfect when space is limited. Straight forward to fit just make sure you plan the route of the cold feed. Be careful measuring the flush pipe length, “ measure twice , cut once”.

Thank goodness this exists!
This was literally the only concealed cistern that would fit in our narrow wall and confined space either side. So glad I found it.
