news Why do I keep seeing overflow pipes (or boiler condenser pipes, or
whatever they are) on people's houses with the pipe curved round 180
degrees so it faces the wall? Why on earth would you want the water
to
run down the wall instead of fall a few inches from the house?

Worried it will damage the wall?

I would think it better not to have your wall soaking wet.

As against having someone scalded? These overflows are only in use when
there's a fault that will release scalding hot water under quite a high
pressure from them when the pressure relief valve opens, which isn't
exactly an everyday occurence. The wall will get wetter every time it
rains.

Bear in mind that as the property owner or occupier, you are liable for
any injury suffered as a result of ho****er escaping form these pipes
and scalding them.

Oh don't be ridiculous. Chances are it wouldn't start squirting precisely
as someone walks past. If it's already squirting, they would avoid it.

We are talking about a one second blast of hot water from the pipe - about a
kettle full of hot water - and then the PRV has done it's job and the water
stops coming from the pipe.
