Hi,

and before anyone says i'm not thinking of moving the soil pipe myself
: )

Just looking for a bit of advice really whilst mulling over some
ideas. The muppet who built the extension on our house (mid 80s)
didn't bother moving the soil pipe from the straight down the middle
of the back wall of the house to the side avoiding the extension - so
i've got a larged boxed off pipe running through the roof of the
extension (which is the kitchen).

What's the problem with that you may ask? well i'm thinking of
creating an open plan kitchen/dining areas to make best use of the
space and there's a bloody great pipe in the way.

The floor of the extension is contrete and from what i can gather the
drains run parallel to the back of the house. The house is a small
terrace 1930s and there's only one toilet at the back upstairs.

My neighbour's got the main manhole cover in their garden and i've got
what looks like a modern oval shaped inspection cover about 1m out
from the back of the extension.

Anyway - to cut a long story short i want to get the pipe moved over
to the end of the extension as it isn't the full width of the house.
The drop angle from the toilet wouldn't be a problem as the roof of
the extension is low enough.

Would it be a case of digging up the concrete floor in the extension
and re-routing the drains, or could the section be sealed and a new
connection added to the drains at the new location (assuming the
drains are there and accessible etc etc)??

I know nobody can give me an exact answer and i don't want loads of
posts saying "how long's a piece of string......" but just a "leave it
alone" or "probably not too much trouble - probably cost you a few
hundred quid govner!!" would be useful.

Cheers in advance.

Sounds easy enough. The existing drain should go to your local inspection
chamber. Test this by flushing the toilet and looking the the inspection
chamber. I assume one bathroom here. It is a case of digging up around the
inspection chamber and diverting the soil pipe to the new position on the
outside wall. Run the drain pipe up the wall to the existing toilet
position. Make sure you use plastic pipe that can be run externally.

Where is the kitchen sink connected? Is it to the exiting stack?

See:
http://ww.hepworthplumbing.co.uk look at the HepVo traps. Using these you
don't need to run the stack above the eves. Just replace the basin, bath
and kitchen sink with these traps. Only every 4th or 5th house requires the
stack run up to the roof, or at the end of a line.
