Leak proofing round a soil pipe when building a conservatory
bp
I am almost ready to purchased a self build conservatory, but I have 1
problem and would like some advice. THe conservatory will have a
polycarbonate roof, and is of the lean to type.
There is a soil pipe on the wall where I want to fit my wall plate. I
cannot change the location so I need some advice on how to fit round
this. I have seen 2 options (from other photographs)
1) Cut the wall plate in 2 and fit either side of the soil pipe. Cut
the polycarb sheeting to the shape of the pipe. In effect this would
be a 'U' shaped cut in the sheeting. Then seal around the polycarb.
I am having trouble working out exactly how I would seal/flash around
the back of the soil pipe. What I have seen somewhere was just a
whole load of sealer piled up - hoping that it wouldn't leak. It did
not look very safe or reliable.
2) The only other option I have seen is where the builder built out
from the wall using timber. Large battens were fitted to the wall
either side of the soil pipe. Essentially a structure was built up
and fixed to the wall around the wall pipe. The conservatory then
starts proud of the pipe. The wall plate is fitted to the timber
structure. The wall plate does not need to be cut, nor does the
polycarb sheeting. You still have to seal up/flash the timber
structure, and I could not see how that was done, but I am assuming
the builder chose that option as it was preferable to cutting the
sheeting because it would have been easier to seal/flash the timber
than to seal/flash sheeting that had been cut.
So can anyone recommend which of these is the better option, in terms
of getting a leakproof roof.
Either way how would someone flash up the soil pipe
May be there is a better option - if so I would like to hear it.
Many Thanks

Thanks for the reply, but I cant see how this would work. I live in a
2 storey house and the soil pipe goes all the way to the top. I would
have to climb al the way to the roof to slip it over the top?
I could find a join in the middle - or even create one I guess. Its
just more hassle as I did not want to touch the soil pipe in any way.
May be there is no way round this

==================================
If you have a flashing on the house wall covering the wall plate this will
work - it worked for me. You might have to vary the details but the
general idea works.
Cut two squares of lead flashing about 12" square (but to suit your
dimensions). Cut a circular hole in each about an inch less than the
diameter of the soil pipe. Use a pair of pliers to make a 1/2" upstand all
round each hole so that the hole is now the same diameter of the soil
pipe. Now make a cut in the side of each so that the piece of flashing can
be fed in from the side - requires some bending, and the cuts must be in
opposite sides. Make sure that each of the pieces of flashing can be fed
under the wall-plate flashing. When both pieces are correctly positioned
and tamped down, run a bead of silicone around the joint between the pipe
and the small upstands made in the flashing. Mine has been in place for
about two years now with no leaks.

Great. I had to read it twice but now I understand - and it seems
workable - for me anyway.
If I choose this method, it doesnt matter how I start the conservatory
Thanks very much

It is a bit confusing so I've just had a look at mine through an upstairs
window. The important thing is to get one of the two squares of lead
overlapping the other from the top rather than the sides. The general idea
and the technique are the same so I hope I didn't confuse you too much.
You might also run a bead of silicone or other sealant around the outer
edges if you think there is any danger of strong cross winds driving rain
in from the sides. Mine is in a fairly sheltered position and hasn't
needed this.

There is an easier way, cut the soil pipe off below the conservatory roof and
add an air admittance valve to the pipe

pipe, rather than vent pipe a decade ago) just let the shit splatter on
the roof?
