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.




Assuming you have more than one house on your sewage treatment plant,
and they are spaced closer than half a mile apart...possibly
