I had a look at the UK.DIY FAQs and there doesn't seem to be anything on
drainage, particularly soil pipes and inspection chambers. Can anyone point
me to anything useful? If not I'll try and describe my problem/query here.

Thanks

OK, thanx. Its not really a problem, just finding out what to do.

We are moving kichen and bathroom, so the drains need rerouting. We've
been
let down by the guy who was doing the work (delay, delay, sorry, family
problem, .... can't do so I thought sod it, I'll do it myself - I've
now
got a nice set of trenches and some exposed clayware soil pipe.

One part is the kitchen waste pipe, from the kitchen back wall to where it
meets the existing drain. This goes 2-3m in one direction, turns 90
degrees, then 3-4m to the existing drain. Later, we may have an upstairs
bathroom, in which case the soil pipe will drop to where the waste pipe
leaves the kitchen. For this reason we are going to put in 110mm pipe so
that we don't have to redo it again

The question is, how do I do the 90 degree bend. I've got the Hunters
catalog and downloaded their specification docs (we're using PVC
throughout) but I can't see an obvious fitting for the 90 degree bend,
other than a full-size 5-to-1 inspection chamber, which seems a bit
overkill. Also, the drop from the kitchen to the existing drain is only
just enough, and the 5-to-1 has a 50mm (ish) drop between the pipe in and
the pipe out, which I want to avoid if possible.

One possibility I though was to use a channel bend and build it into a
brick/concrete chamber. This has the added advantage of being stronger -
it's pretty close to where a vehicle wheel will go heading into the
garage.

So, is there any online info on this and what the regulations are, or can
someone point me at a how-to book that the (hopefully informed!) layman
can
follow?

Thanx
Mike



Have a look through the Osma site for the bits and pieces you'll need. Then
you'll have a better idea on what to and not to use in this project.

Do you really need a chamber at the point where it turns through 90deg? Have
you considered using a T junction instead, and bringing a pipe up from the
"unused" leg of the T to a rodding eye? That would enable you to rod one
section - either from the house to the right-angle or from the right-angle
to the drain - depending on which way round you put the T. This should be ok
provided you can rod the other leg from the other end. Is there a chamber at
the point where your new pipe will join the existing drain? If so, you can
rod that section from the chamber end.

At the end of the day, you will need to get this inspected and passed by
your local BCO - so I suggest that you seek his advice at the outset.

Chambers are cheap, have expansion knock out holes for future use and will
be easy to clear out any blockage. I would go chamber.

Pipes need to be 100mm or bigger



You need a rodding point and/or inspection chamber at every junction,
and every change of direction.

The system needs to be moderately gas tight and laid in e.g. gravel
lined trenches to ensure undue stress is not applied.

Overall it needs a fall of between 1:60 and 1:100 for adequate operation.

At some point it needs to be vented, to stop pressure build up.

Thats about it for undeground drainage.

Full details in appropiate building regs.

Thanx for the feedback. The Osma site has piccies of all their bits, I
reckon what we need is a bottle gulley. The T-junction and rodding point
idea was neat, but we'd need to rod both ways from the corner.

We've had the BCO guy round to OK starting the work so we know that the
corner is basically OK.

Mike
