Hi my waste pipe from my bath is about 3m long.
It runs from the bath trap to a t peace then up hill a little bit to a bend and then to the soil pipe.
The sink waste also goes into it just before it enters the soil pipe.
There is t just after the trap with a small aav on it. Is this needed as the soil pipe has an aav in the loft space.
I would like to run it so it all runs down hill and wondered if i could remove the aav under the bath.
Thanks
