I was planning to remove the soil pipe and cap it off at floor level. But after reading other people post's I have decided not to. While checking the soil pipe I have found a few things that I need answers for as I don't think that they are correct.
1.The soil pipe outlet end is in my loft
2. The end has what looks like a polystireen bung sat on the top.
3. The ceiling in the En-suite directly at the side of the pipe has black mould coming through the paint. This has been painted over twice and keeps coming through
Should the end be open in my loft,or have a bung sat in the top. What can be done to stop the mould on the ceiling coming through. The house is just over 10 years old would it possible to get the original builders back if this is wrong.
