Fall On Basin Waste Pipe

[*Dan*]

Our basin waste pipe is 36mm outer diameter (32mm inner) and runs about 2 metres into the soil box. The floor is up at the moment and was surprised there is literally no fall on this pipe going between the holes in the joists. I am planning on elevating this with some rubber clips but do not want it to be too high. Is there a recommended fall for a basin waste pipe like there is for a toilet waste pipe?

thanks

Oh, thought this was going to be one of those ‘how did you get that stuck up your arse' pictures.

2.5 degrees, or 44mm per metre

Put a spirit level on the pipe to see the actual fall.

I did there was nothing the tiles were holding up the pipe to create the fall
