I'M LOOKING BACK on photos that document the construction of a new home, trying to figure out where to start investigating a leak.
Foul air is leaking from a home sewage system, under floors and in toilets. The en suite toilet (shown before it was finished) and the attic air admittance valves don't smell. Part of the investigation centres on a review of pipes as documented in photographs because the home has no blueprints. After spending a half day mucking around (literally opening and spraying high pressure water into the outside access pipes), some of the smell has subsided. This suggests problems with the outside sewage lines.
In the past, we've received helpful advice when I've posted issues on my blog and on Google Plus. If you're a reader with an idea, please drop me a comment wherever you spot this foul blog post.
