Ok, I give up, I can’t work out where my drains go and one of them is blocked. Jetting and rodding does not do anything, but I can get the full length of the rod in, so I expect the rod may just be wrapping it’s self in a circle in a hidden manhole.
So I am looking some someone that is an ace with the drainage CCTV system and also has a drain tracing system so any discovered junctions and missing manholes can be marked on the ground.
This is not an emergency as the drain just takes a downpipe and the washing machine. I rather not use one of the “Dyno-Rod� of this world.
I am locking for a full sketch plan of all my drains as well as understanding what the blockage is, the drains are from the 1930s, in glazed clay pipes.
