as if the pipe has ever gone outside. The top of the soil pipe looks
correct, it looks like it was made be BAA.

Is there a danger that the gas has no were to go !


Are you sure it is and end cap? It is more likely that it is an air
admittance
valve. I thnk there also need to to be a pressure relief somewhere in
the
system but I'm not sure.

That's my understanding as well.

Very common to find a durgo in the loft, but there nees to be an 'open
end' somewhere.

Yes, every 4th or 5th house.
