Bath waste

[shifish]

Is is acceptable to run a bath waste pipe so that it just runs into an outside drain? I have often seen kitchen sink wastes arranged like this, but not baths. The reason I want to do it this way is that the fall pipe I would otherwise connect to is above my conservatory roof making it difficult to access.

Its ok on a bungalow to do this. It would look strange having a 40 mm waste pipe clipped down the wall from an upstairs bathroom though.

Can't see any problem apart from it looking aesthetically wrong.

See what the others think.

At what point is any body gona ask if the drain to be used is top water / soil or a combined system. ]

Depends where you live. Combined or separate? Good point!

Thanks for that folks.
The drain already takes waste from my kitchen, does this mean it's likely to be soil or combined rather than top water, assuming things were done properly?

Open a manhole, flush loo.........run sink water.same pipes .ok

Your current sink drain outside will have a trap (U bend) to stop the smells from the drain coming up. You should see standing water under the grating.
