On the other side of my mechanical room's wall, we are putting in a small powder room. The sink is going to be on the wall below the boiler valves, which is represented by my awesome graphic. I was hoping to just pop the drain through that wall and down to the current ABS drain line in the photo. The drain just services the boiler and the hot water tanks relief valve, so hopefully never used besides testing the valve. The slope is adequate from there going to my stack.
- Would this be appropriate to do?
- Should I have a little trap on the bottom of the vertical pipes coming down from my tank and boiler? I was once told I should, but these would be dry since those relief valves hopefully aren't releasing water often. So, would that do anything?
