Just how flexible should drain rods be?
I just bought a set from Wickes with the hope of clearing an apparent blockage I have somewhere in the underground pipes from my downstairs cloakroom toilet and basin. However I cant even get them past the first bend in the toilet soil pipe in the floor and I am reluctant to try forcing it too much in case I damage the lining of the pipes.
For a single rod element, about a yard long, it takes a lot of effort to bend it even through 90 degrees. It seems very stiff.
