we have a small, ex coal chute, cellar in our victorian property and for the first two years it has been bone dry.
recently it sprung a leak in a side wall that is getting progressivly worst - about 12 litres a day coming in at the moment.
At this point I am not worried about that itself - just the smell is terrible. Everyone who has come round so far says it is "probably not sewage". Is there any form of test I can myself to prove it is clean, sewage, dirty etc.......
Thanks for any help from anyone!
