House smells awful - soil stack help please!

[Madrab]

I'd be looking at removing it completely

If junction A alone is the cause of the smell, could I apply sealant on both edges to seal it up? Once our works are complete this entire bit of soil stack is going to be redundant, as the washing machine is being moved elsewhere. so when we get to that stage, I'm thinking we can cap off the entire run.

I think the repair would be temporary

Thanks Madrab. That'll teach me to read it properly....
