Usually the first step in clearing a clogged drain is to take out the waste that is clogging the opening of drain.

A drain rod would be needed to remove the hard blocks that cannot be removed using plunger. Insert and push the drain rod into the drain pipe till it hits the blockage. After inserting it well into the blockage, turn the drain rod to the right so that it can split up the blockage.
