Due to my soil pipe mine was about 2cm away from the wall when I
installed it. Knowing how rough some of our house guest can be in their
actions I fixed a small strip of wood to the back wall the width of the
gap to absorb any sudden impacts against the cistern. If mounted at
about 2 thirds of the way up the cistern then it's not easily visible
and painting it white also helped it to blend in.
