Hi
I would appreciate your feedback on the drain configurations outlined in the drawing.
Option 1 is our preferred layout. However, I'm concerned about whether the WC connection with a long radius will effectively connect to the existing combined drain. I am avoiding the drain connection directly to the manhole. If this isn't feasible, Option 2 retains the WC in its current location. Option 1 offers more space, which is important for me as an ambulant person. Due to space constraints, achieving Doc M compliance isn't possible, but I am satisfied with Option 1's layout.
The walk-in shower will measure 1200 x 900mm. I would appreciate your thoughts on the proposed drainage setup. It's worth noting that only one house drains into my manhole before it continues to connect four houses down the line to the sewer on the road.
Please let me know your views on the drainage proposal.
Thank you
