Some advice and help please.
I have an underground drain – 100mm nominal diameter - which services my downstairs toilet and runs down the side of my house one meter to invert level for about 10 metres and connects perpendicular into a communal drain which runs parallel with the back of the house. There is an insp.chamber where the drain exits the wall line from the downstairs toilet.
One year ago the drain blocked, called out Dynorod who took a look and said a conifer shrub at the junction of my drain and the communal drain had roots which were causing a problem. They cleared the blockage and sent a camera down - £££££££ - which confirmed that the roots were not a problem and that the blockage was just a build up of ``solids’’ and paper and that the drain was good as new.
Three months later, the drain backed up again, but this time I used flexi rods with a rubber plunger and gave it a good rodding and cleared it no problem. The drain backs up periodically and out comes the plunger. My question is, why does it keep blocking? if the original camera survey found no cause for concern.
My appreciation and thanks in advance.
