Most of the time the waste lines in a container building work by gravity – basically on the principle that water and…well other stuff go downhill. It presents a lot of challenges in shipping containers to keep all the waste pipes at a decent slope. In this earlier video I talk about the challenges. On this recent project we used pressurized sewer lines because we didn’t have a sewer to connect to, so we had to pump into a holding tank. To my surprise, it solved a lot of other problems. In my video I go through it.
