This is a before and after shot of a drain in a private house. The blockage was cleared by high pressure jetting. Simple when you know how, we have seen home owners chucking all sorts from bleach to salt to washing powder down drains.
This is a job we carried out yesterday. Existing 4" pipe was incorrectly installed into the side of the man hole. This was causing on going blockages. We excavated the outlet pipe. We then installed a new pipe into the middle of the man hole re benched man hole and left the work area as it was before we carried out repair works.
