Soil pipe angle??

[J9ABF]

Hiya Guys,

I am going to core drill through the wall behind a wc and join in to the soil stack outside. Do I need to angle the core drill to achieve a fall going outside or can I just drill through horizontally? Advise much appreciated.

if your toilet is direct on other side of wall from soil pipe just core drill straight through
you will have enough play in the hole when fitting 110mm pipe and pipe will only be short.
min fall on pipe is 18mm/m

dont make the common mistake of having the pipe fall too sharrpl, this caan be worse than not as much
