WC soil pipe in loft
I have just moved into a house, built about 1965-1970. The strange thing is
that the soil pipe goes into the loft but is then sealed with an end cap, I always presumed that the soil pipe should go out the roof. It does not loof 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. Bob |

So how does the gas from the drainage system get out of the stack pipe !
As we are getting a drainage smell in the bath room, sound like the valve is broken ! What is the best make to fit and is it a simple job. Is the gas a health hazard ! and are there testers to check it. |

WC soil pipe in loft
On Thu, 13 Nov 2003 22:05:20 GMT, a particular chimpanzee named
randomly hit the keyboard and produced: I have just moved into a house, built about 1965-1970. The strange thing is that the soil pipe goes into the loft but is then sealed with an end cap, I always presumed that the soil pipe should go out the roof. It does not loof as if the pipe has ever gone outside. The top of the soil pipe looks correct, it looks like it was made be BAA. I suspect that the logo on the top is BBA (British Board of Agrement) which is the body that certifies building products. If it is there should be a number underneath (yy/nnnn) which if you plug in to the certificate search of http://www.bbacerts.co.uk/frames.html, should come up with a certificate for an air-admittance valve. -- Hugo Nebula "You know, I'd rather see this on TV, Tones it down" - Laurie Anderson |
