My impression is that a lot of the plumbing added to existing buildings in Britain was put on the outside
because it wasn't practical to do it all inside - simply pierce the walls where you needed to run a pipe
inside to a fixture.
Although I would not disagree with the above, read on its own it could be misleading. There are three main
elements to the plumbing system of a British building and each would have a different relationship with the
outside of a house.
Rainwater starts outside a house so there would be little point in bringing it inside. Rainwater downpipes
were traditionally run outside buildings.
In grander houses these were run inside the house, in less grand houses they were run outside round the
back of the house.
These were invariably run inside the house.
