Hi i wonder if someone could help me my manhole outside the back of my house is blocked, i put 70feet of rods down there (thats all my rods) and it doesnt get to the blockage, and from the direction of the manhole i would say its going into the neighbours garden also. i rent the property and cant afford to call out a plumber my question is where should the next manhole cover likely to be surely there should be another one along this run thats not too far away. i also thought the drain run would have gone into the manhole in the road at the front of the house or is it likely just to run to the bottom of the garden into the neighbour who is joined at the bottom of the house.
