Hi,
Can anyone tell me if there is a permissible limit to the length of an underground 110mm soil pipe (before it meets the main, public, large-bore pipe running under the road/street?)

Thank you..

I suppose it depends on whether there is a "standard depth" for street
sewers. The attainable slope on your soil pipe will determine its maximum
length (I guess). Not an expert though...

If only your property is using this pipe then provided you have access
points at every bend and the fall is correct over the entire length,
then the only limit is how deep the public sewers are.

The estate where I live uses 110 mm to interconnect blocks of terraced
house but despite the gentle slope, the run they take before
joining the 150 mm stuff is like a dogs back leg.

To much fall is as bad as not enough.

Thanks for the replies. I can't find anything in the Building Regs Part H regarding maximum length. This surprises me, because when you flush a loo, that gallon or so of flush water has got to carry the human waste along, and the longer the run, the more of that water will be used up moistening the inside of the soil pipe. So if, say, you had a run of 1/4 of a mile, I would imagine that nothing would reach the other end, even with the correct gradient. In my case, the entire length would be about 35 mtrs, and with the correct gradient.

Flawed thinking.
The inside of the pipe never dries out, it's underground so always out of
the sun, dripping taps, handwashing and every other drop of water that goes
down the plugholes of your house keep it permanently wet.
Turds may lounge around a while during a long run, but they won't dry out
and cause a blockage because of the reasons mentioned above. Next time
someone flushes a slash or has a shower it'll continue on it's journey to
the sewer.

35 metres is nothing, I've put them in twice this length and watched turds
sail past the bottom of the main manhole into the sewer beyond...there's
usually not much left of them by the time they've fallen 5 metres down a
vertical soilpipe and into the drain.

The limitation is that of depth. You have a minimum and maximum rate of
fall, that in turn implies your length is constrained by the height
available for that fall.

You need to consult the plowperson on this issue.

Sadly this group is getting progressively less fun to be about. The
level of OT stuff and politics certainly does not help, but the never
ending stream of snarky comments and insults in particular (from you and
others) is not adding anything of value, and gets on my tits.

Amusing jokes are one thing but silly interjections in an otherwise
useful discussion is infantile.
