Plumbing Terms

[Chineplate]

I've just been given the hot and cold water services plan of a new house that I'm buying. On the diagram are terms such as Drop T/B, Rise F/B, Drop F/A and Rise T/A. I'm struggling to work out their meaning, can anyone help.

I've no idea, but your builders may be able to make sense of it.

To Below, From Below, From Above and To Above

Many thanks SandyLion, that makes sense.
