Hi all
Every few years I get a blocked main drain, I think primarily because the system is quite old, and includes an interceptor trap where the drain presumably enters the main sewer.
The situation is the drain is partially blocked, though it does drain slowly after putting a tub of caustic soda down it. The rodding eye of the trap is clogged with crud. So I'm not quite sure how to proceed with rodding it. Should I try to force the crud in the rodding eye down through the trap, or should I try rodding through the manhole cover which is about 20 meters from the trap.
Or flush more and more caustic soda down the drain
Any help would be appreciated
cheers
