Planned to work out some leadwork voodoo to get this soil pipe through the polycarbonate roof...
Then remembered durgo valves!
But, must be 200mm above highest point of water exit. Which is sink overflow? (One bathroom, no tank in loft.)
1. What if I can squeeze a external durgo on top and under the polycarbonate? What goes wrong?
2. And is there any advantage if I still have to go through the roof with soil pipe, to putting a durgo on a shorter stub of soil pipe?
I saw a proprietary 110 flashing slate today and the rubber part alone won't get between the soil pipe and the wall.
