fit dishwasher piper under 120 cm wide corridor

[sebas123]

Hello,

I have a dishwasher installed in a wall of a 120cm wide corridor. On the same wall there is gully and so there is a pipe going to the gully on the floor. See the picture.

Now I need to move the dishwasher on the wall in front. So the pipe would cross the corridor and therefore it must go under the concrete. (Then I'll box the pipe along the wall.)

What do you suggest ? Should I build another gully on the other wall across? or a simple shallow trench and then in somehow connect the pipe to the existing gully ?

Thanks

If you're going to dig the floor up anyway, may be worth seeing which way the gulley outlet goes, and rejigging it to move the gulley, but if you dont want to do too much work, then just run a new waste under the concrete. A Boss connection will suffice to connect new waste into the existing upstand of the gulley.
