Is this legal plumbing?

[Wilkinson]

We have just noticed our adjoining neighbour has had some plumbing done which crosses into our boundary.
The plumber has drilled through the wall and put a drainage pipe into our soak away rather than into their own soil pipe which I’m sure is what should have been done.
We do share a down pipe from the gutters (middle pipe, 2nd picture) which goes into this soak away, but we each have our own drain/manhole cover in our front gardens, surely this is where the new pipe should go?
Any advise would be grateful.

Not the end of the world, but strictly speaking it should not be there without your permission.

 

[Bod ...]

Don't put up with it. Any decent plumber would'nt do such a thing.

 

[Wilkinson]

No one asked for permission plus whatever drains into it could block our drain not theirs!

And should probably go to a soil pipe, not rainwater.

 

[Wilkinson]

That’s what I thought, lazy plumbing obviously

It's most probably a shared rainwater/foul drain.

Is it kitchen or WC basin waste?

 

[Wilkinson]

I’m not sure as I haven’t had the conversation with them yet, the big pipe is rainwater but it does look like sink pipe to me.

Obviously I can’t confirm just from a photo, but if it does go to a soak away and it’s foul drainage they can be prosecuted by your local water undertaker.

If its kitchen and they eat deep fried food your trap may block and you will have to deal or pay for it.

Looks like old houses by looks of doors and cast stack

That’s my thoughts exactly. It should go into their own drain which they are responsible for, although they are Victorian houses we are lucky enough not to have to share drains.

Would foul drainage mean bathroom and kitchen sinks too?

Yes.

 

[Wilkinson]

Yes.

Turns out it’s an over flow for a water softener - so shouldn’t cause a problem - should it? Would have been nice to have been asked though!
