Hi everyone, we have had this drain problem for over 4 months, water from the kitchen sink spills over the drain and disappears down two holes at the side,these holes are getting bigger and are about 8 to 10 inches deep two garden slabs nearest the holes are very loose and wobbly when stood upon. recently the drain has blocked completely and water either backs up into the kitchen sink or empties into the washing machine. we have tried unblocking the drain with rods etc and we have checked pipework under the sink and they are fine but our landlord is still insisting its a blocked pipe.
