I've noticed that a lot of new houses have the old style outside
soil drain stacks, usually in black. They look horrible. Has
anyone an explanation
for this? I thought that inside soil drains were adopted 30-35
years ago.

The pipes running down the outside of the walls may not be soil
pipes, they may only be rain water pipes from the guttering on the
roof. What diameter of pipes are they ? Anything less than 110 mm
in diameter and they are rain water drainage.

The pipes certainly looked more than 110mm diameter. There were also
diagonal feeds into the vertical stack, presumably from en-suites,
cloakrooms etc. The rainwater guttering was separate, so I'm convinced that
these were soil drainage.

The plastics that are used today are not really susceptible to frost damage or
weathering, so the pipework can be taken outside the property again, unlike the
cast pipes of yester' year. They are also more secure as people find it
difficult to climb up them without them pulling out the wall or folding up with
weight, so this to allows the new plastics to be designed for external use
again.

They do look horrible on some sites, but they can be painted to help them match
in with the surroundings. Saying that, some councils are going back to the old
style of black pipework everywhere to help new builds blend with the old.
