Two available rodding points opened and rodded with full rod length, no difference. One was on rear lawn pointing towards rear stack, the other after the cloakroom toilet pointing to the front drain. When flushing toilets at rear no water appears at main drain at front of building. When toilet on front stack is flushed water flows freely through main drain.
This is pertinent of a blockages. Perhaps a diagram might be better to explain things?
