Noisy flexible soil pipe

[Heye]

Hello

I hope someone can help.

I live in a flat. The person upstairs to me has carried out some work and moved their toilet. Now the soil pipe behind my bathroom wall is very noisy particularly when the toilet is flushed. We think the problem is that the soil pipe (behind my bathroom wall) doesn't go straight down but travels diagonally via a flexible pipe and waste is hitting the pipes. Not sure why it is like this but it is.

Is there a problem with the flexible pipe that is causing this?

Are there alternative pipes which could solve this problem without the risk of blockages?

Also, the pipes are behind a tiled wall and there is no access panel. Is it possible to remove a large tiled section and then replace it again. We've had a building firm round and they said they could only smash through the wall.

We are considering soundproofing etc but not sure that that will solve the problem on its own.

Many thanks for your help

The flexible pipe has ridges on it and perhaps the 'solids' are running over it like a washboard. I'd change it for smooth pipe.

it part of the building structure and as an individual you shouldnt be touching it withh out other leaseholders permission, after all you take it out and mess with it, boyo up stairs is entitled to carry on flushing his loo still and thats worse than a bit of water noise. Talk to the building committee etc first, for options and then start looking behind walls to see whats going on.
