It might have been to avoid sewer gases from flowing up the drain pipes from
sinks if the water in the U trap got blown/sucked out. I'm not sure why it
was fairly common (or even universal) for older plumbing but is very rare on
modern plumbing, even on houses with external drain pipes.

I will make a confession. When I was very little (maybe around 5 years old)
I used to have an infatuation with plumbing, and knew various houses on my
walk between home and school not by who lived there but by the pattern that
the pipes made on the wall. Embarrassing to admit such nerdy behaviour!
There were some houses that had steeply-sloping pipes from sink/bath
directly into the vertical soil pipe, but which had a second pipe that
branched off the sloping pipe and entered the soil pipe higher up. That
always intrigued me. I wonder if it was a way of avoiding the U-trap water
from being sucked out.

It was even done for rainwater pipes: https://goo.gl/maps/6zvySgaiNRRny41w5
shows the pipes from three gutters draining into a common pipe, with two of
them going into a hopper and another going into a side branch of the down
pipe.

I fail to see why this helps. Let's say I try to empty my bath, but the downpipe is blocked outside. I'd rather the bath just didn't empty, then I'd investigate the problem. I don't want the water to come sloshing out all over whatever is below it outside, which could even be people.

It could make sense to stop water going back the wrong way - eg. a 3rd floor bath emptying into a 2nd floor bath and flooding the room. But there's no point on the highest floor, which is where I've always seen it.

That makes sense, a smaller version of the big pipe that's usually placed just after a toilet.

But the extra pipe allowed air in from higher up instead of pulling on the u-bend water.

If the pipe is blocked and you empty your bath, then if you have a box, the water goes everywhere outside. If you have no box, the bath just stays full and you call a plumber. The second one is preferable obviously.

Good point, I hadn't thought of roof water going into the sinks and baths.

Do you mean a hopper with the pipe going into it? I still have one on my
upstairs sink. Two possible reasons, Somewhere for noxious fumes to come
out, and a simple way to allow for blockages as you suggest.
My drainpipe has a cranked piece of pipe going up above the gutter to take
the fumes away, but it only takes stuff from the toilet and one would not
want an open hopper on that near a window, but for drains from baths and
sinks its ok usually.
Incidentally, I live in a terrace of four houses, but only the end two have
drains from the gutter, resulting in, when it rains heavily it cascading
down on right angled bends near my inset porch. I put in an extra drain pipe
here into a soak away, however the shrub loved the water so much, a
camellia, its now taken over the soak away and we get a nice little flood by
the front wall.

It might have been to avoid sewer gases from flowing up the drain pipes
from
sinks if the water in the U trap got blown/sucked out. I'm not sure why
it
was fairly common (or even universal) for older plumbing but is very rare
on
modern plumbing, even on houses with external drain pipes.

Perhaps the venting wasn't so good in those days? Although I don't see
why, the vent pipe sticking up to roof height has always been pretty much
the same.

I will make a confession. When I was very little (maybe around 5 years
old)
I used to have an infatuation with plumbing, and knew various houses on
my
walk between home and school not by who lived there but by the pattern
that
the pipes made on the wall. Embarrassing to admit such nerdy behaviour!

Sounds sensible to me. When the mind is doing nothing during your walk,
it's going to think about something.

There were some houses that had steeply-sloping pipes from sink/bath
directly into the vertical soil pipe, but which had a second pipe that
branched off the sloping pipe and entered the soil pipe higher up. That
always intrigued me. I wonder if it was a way of avoiding the U-trap
water
from being sucked out.

That makes sense, a smaller version of the big pipe that's usually placed
just after a toilet. When the sink finished emptying, the water flowing
through that steep pipe and filling it's whole diameter, would suck the
air behind it. But the extra pipe allowed air in from higher up instead
of pulling on the u-bend water.

It was even done for rainwater pipes:

Not really because the overflow happens in one place and can
be organised so that is never a problem. With it overflowing
the gutter wherever the gutter happens to be lower, you don't
have any real control over what it overflows onto and the lowest
point in the gutter will change over time. It wont with the box.

Good point, I hadn't thought of roof water going into the sinks and baths.
that's OK .....nobody does we always tried to discourage builders from

it ... we could where it was a two pipe system though.....

No its not; Much more convenient for the bath
to keep working until the plumber shows up.

the fumes away, but it only takes stuff from the toilet and one would not
want an open hopper on that near a window, but for drains from baths and
sinks its ok usually.
Incidentally, I live in a terrace of four houses, but only the end two have

the front wall.
Brian

in the olden days where connections were made from sinks to cast iron
down pipes in lead and were not very well sealed it was very important
not to have pressure in a foul or waste pipe and have plenty of
venting.....sometimes with a hopper collecting waste and rainwater
.....very true

It might have been to avoid sewer gases from flowing up the drain pipes
from
sinks if the water in the U trap got blown/sucked out. I'm not sure why
it
was fairly common (or even universal) for older plumbing but is very rare
on
modern plumbing, even on houses with external drain pipes.

Perhaps the venting wasn't so good in those days? Although I don't see
why, the vent pipe sticking up to roof height has always been pretty much
the same.

I will make a confession. When I was very little (maybe around 5 years
old)
I used to have an infatuation with plumbing, and knew various houses on
my
walk between home and school not by who lived there but by the pattern
that
the pipes made on the wall. Embarrassing to admit such nerdy behaviour!

Sounds sensible to me. When the mind is doing nothing during your walk,
it's going to think about something.

There were some houses that had steeply-sloping pipes from sink/bath
directly into the vertical soil pipe, but which had a second pipe that
branched off the sloping pipe and entered the soil pipe higher up. That
always intrigued me. I wonder if it was a way of avoiding the U-trap
water
from being sucked out.

That makes sense, a smaller version of the big pipe that's usually placed
just after a toilet. When the sink finished emptying, the water flowing
through that steep pipe and filling it's whole diameter, would suck the
air behind it. But the extra pipe allowed air in from higher up instead
of pulling on the u-bend water.

It was even done for rainwater pipes:
https://goo.gl/maps/6zvySgaiNRRny41w5
shows the pipes from three gutters draining into a common pipe, with two
of
them going into a hopper and another going into a side branch of the down
pipe.

I don't see the point in that. If the downpipe became blocked, all that
does is make loads of water pour out of the box instead of just spilling
from the gutters over a wider area. I'd say it makes the problem worse.

Not really because the overflow happens in one place and can
be organised so that is never a problem. With it overflowing
the gutter wherever the gutter happens to be lower, you don't
have any real control over what it overflows onto and the lowest
point in the gutter will change over time. It wont with the box.

My gutter pours onto the postman waiting at the door.

No urgency to fix the problem.

but what can you do ...

I always thought of soak aways as a crazy idea. You're taking rainwater and putting it into the ground, so achieving nothing. Myself and my next door neighbour have the complete opposite. A hole in the ground with a pump in it. Which pumps water out into the drain to lower the water table in the garden so things aren't so soggy.
