The invention is suitable for use in traps in buildings which are connected to the common sewerage system. Said invention provides a technical solution that prevents the obstruction of the trap by means of an alarm whic h is installed in the conduit wherein the water is diverted due to gravity whe n the conduit is obstructed. Said alarm signals any obstruction in the conduit so that it can be cleared without waiting for the consequences of such a situation to occur.
