Problem: The sewer pipe was blocked. The sewer was able to flow again after clearing a small gap, with the high pressure jetter, allowing us to see what was causing the blockage. Somehow a sizeable rock had made it’s way into the sewer pipe and was sitting in the boundary trap blocking everything up.
Solution: We had to excavate down to the boundary trap and cut out the pipe work above it, to be able to reach in by hand and remove the rock as well as a sizeable  stick. We then replaced all the pipe work and concrete encased the boundary tray.
