Drain/General Advice
Bought a house 6 months ago and have been non stop dealing with issues such as Ant infestation in rear wall, significant leak in rear wall, gas boiler broken when I moved in, gas stove unusable, maggots out back, rising damp looking like someone had just run a bottle of water around the walls etc with the list I have I could go on. Sellers and their solicitors completely ignored contact.
Yesterday in lean-to I noticed what I thought had just been the paint old paint crumbling was getting significantly bigger, previous owner had 2 layers of carpet tile ontop of original vinyl (assumed due to leak in rear wall). Lifted up to find what either looked to be carpet moths or maggots all throughout the green tiles underneath so chucked them out and while doing that found (photo).
I think it’s a drain directly inside my lean to? The pipe goes to the sink. It’s a foam pad with another one underneath but wrapped in a plastic bag, I can’t and don’t want to pull it up enough to see exactly but can hear water running from the sink in the lean to clear as day now. Surely someone can’t have been stupid enough to do this, right? Also is it even legal to sell a house with an undisclosed drain inside the house?
