Building defects database - Blocked gullery

Record details

Blue detergent water in a blocked back inlet gully. The cast-iron pipe takes bathroom waste water into a hopper at the head of the pipe. Nowadays the pipe would discharge below the gully cover grill or connect directly to the branch drain. Regular clearance of external gullies is necessary to prevent leaf litter and airborne detritus causing blockages. Pre-formed cover guards can prevent blockages from blown material, abuse or accident.
