Drainage Query

Hi I am about to install a replacement Bath and Wash hand basin and an additional shower but only have one 1" 1/2 drainage pipe that I can use.

If I fit anti vac traps to bath/whb/shower can I connect all three into the same 1" 1/2 pipe without too many issues?

The run will be no more than 3m.

Access to the soil pipe to attach additional 32mm/40mm pipes is almost imposssible without cutting into the stud wall and then drylining / replastering

Many Thanks for any advice

Simply Build It

water will flow away but you will get a gluging noise from the traps and you may lose the water seal.Be careful that bath and basin water dose'nt back flow into tray.Best to increase waste pipe size to avoid probs.
