Looking for advice regarding a sink waste pipe behind toilet waste pipe.

[tmm]

Hi
My sink waste pipe is behind the toilet waste pipe and i need to somehow get my sink waste over the top or under my toilet waste pipe. My sink is going to be fitted other side of bath approx 8 foot from main waste outlet. If i fit a 90 degree bend up and over and back down to the floor and run a waste pipe to my sink under the bath would the waste still work and run outside?
I have attached a photo. Sorry my description is not the best.

Gonna need more info as I’m afraid that makes no sense do you mean basin waste or a sink waste as we’d treat the two as different. Sink kitchen basin bathroom. It sounds as if you’re asking if water will drain if you make almost an “n” shape over the toilet waste pipe. Water will not run up hill

Yeah that’s what I’m asking Riley. Do you know another way of doing it then?

Well the only way to do it is with a continuous fall to avoid blockage. I don’t mean to sound rude but your pic doesn’treally show anything. Perhaps draw up a plan of the bathroom and post. I assume you’re doing it yourself??

The only way is to bring the basin waste above the toilet one can't go lower than what's already there

Hope this makes sense
