What Could This be Causing Damage to Soil Stack Drainage and wastage systems and plumbing help, advice and answers

[geminiuk1987]

Hi All,

I am looking to buy a house and had the Homebuyer's report back with various points on it. One of them says 'leakage is evident from the base of the soil stack and clearly repairs are required'. It has been noted as a 'level 3'.

We have gone back to the property to have a look and picture is as per the attached. Looks like something is growing in behind?

Does anyone have any advice for me?

Thank you in advance,

the incorrect socket has been installed, there may be some leakage but I think is minimal, flush the toilet and see if any water appears on the pipe below the joint
