Hello. I am planning out the DWV for a tiny house on wheels. As a result, I don't have a crawlspace or a below grade in the slab space to work with. To keep the DWV from freezing I'm routing the horizontal runs just under the subfloor. I plan on cutting and sloping a channel in the rigid foam floor insulation to fit the horizontal runs and locking everything in place by spray foaming the gaps then putting in the OSB subfloor. My question to you is my use of a double elbow to join the flow from the two horizontal directions OK? Will it work well? OR do I need to consider an alternate design? If so please suggest.
Any other issues you see in my DWV design?
Thank you.
