Ladies/gents,
Connecting a new and repositioned loo to an existing stack which is inside the house and I really need to put the soil-pipe branch beneath the floorboards. Bog standard (no pun intended!!) family bathroom. Planning on a 300mm ish drop from the loo pan into the pipe, through a 90 then along to the top of the stack, joined with another 90. The horizontal distance is 1800mm and the void beneath the boards is 180mm deep.
110mm pipe would give a gradient of approx 1:30, 82mm pipe a gradient of approx 1:25.
Appreciate any advice upon, and answers to, to following:
1. Are my gardient calcs about right? (I've allowed a bit of a faff for the connections - but I may have missed something)
2. Would these gradients be acceptable?
3. I feel a bit more comfy with the increased gradient offered by the 82mm option; would that be the best option or is 82mm not good for a soil branch of just under 2m?
Many thanks indeed for any and all pointers,
Cheers,
Sam
