Hi all,
I have recently had major works done in my flat, with walls and partitions being removed and redone because of previous damage.
following this the soil stack has gone way louder than it was before, it makes a bad knocking sound as if something is banging from behind the wall whenever someone on the flats upstairs flushes their toilet.
its usually worse when it hasn't had anything go through it for while.
the boxing that encloses the pipe doesn't seem to have any kind of insulation as far as I can see so I figure that is one issue,
but other than that I wonder if there might be any other potential cause we should be aware of or look into?
thanks for any advice.
edit: I'm attaching an audio file of what it sounds like.
