Iwant to move my bathroom to the opposite side of the house and need advice on the waste issue as the underground drain is then on the wrong side. If I put the toilet on the outside wall would I be allowed to put the soil pipe through the wall and then back in through the wall to run under the floor space and connect into the existing drain obviously allowing sufficient fall.

Can't see no reason why you aren't allowed to do this so long as you still achieve the fall rates.

Allow an access point at regular intervals and definately at every change of pipe direction.
