Moving toilet / new waste pipe run

[Bendy]

Hi

Just wondered if somebody could give me some advice.

I've got to move a toilet from it's current position and I can't move the soil pipe on the outside of the house as it runs under the roof a lean to extension.

I was thinking about putting a 90 degree bend onto the soil pipe internally, short pipe run, followed by another 90 degree bend, another short pipe run with a 90 degree pan connector into the back of the toilet, I'm going to stick the toilet on a raised plinth to allow for the required fall in the pipe.

I've attached a plan of the layout ; The number of 90 turns in the pipe work bothers me. Is this a feasible pipe run or am I asking for trouble?

Any suggestions ? Thanks...

welcome to the forum bendy,

you are using a few bendies there lol.

doubt raised plinth necessary only need 20mm fall use an offset at pan to raise fall through pipe a little more to 40mm and put in a rodding point.

For the bends you can get 90 degree with a directional arrow on the side of them for better flow so there is less chance of blockages with a natrual run.
