I need to bore a hole in a joist to take a shower waste. Reading the regs

That is probably a *suggestion* that means in the case of thick plunbers
they will never cause the joist to collapse.
I need to pass a pipe of 42mm diameter!
The joist is right next to a wall at the outer edge of the house - load on
it will never be high.
Exactly. And yet the regs don't take that into account.
