waste?

[lifeloveorange]

hi im a newbie on here, and not a plumber although im pretty good at it. im moving my bathroom to the centre of the house which means all new pipes etc. the question i need answering please is:
can you connect the tolilet waste to the sink,bath under the floor in the house or does it have to run out seperatly i.e waste on its own and sink and bath together.
any help please?🙂

down to the regs, and i cant quote them.

its just not something you want to do though, fecal straight out through the wall whenever possible.
vent straight up, better to vent then aiv all the time
small pipes straight out with reqd fall and bossed into stack, if possible with rodding eyes.

thats the practical, safe way of doing it, helping to ensure you dont have toilet waste backfilling your bath.

good luck
shaun

Go to HMSO website or HMG Planning portal and download a copy of the current Approved document "Guide to the Building Regs" Part H Drainage.

Gives you some good ideas and also by following them makes it legal.

Also I notice you are running under floors, check the same place for guidance about fire checking. Soil pipe made of pvc, can act as a flue and spread fire like mad if not properly fire checked inside a building.

I am not saying its like that in your situation, but its best to be aware of these factors than not be aware.🙂
