[In case your sewage pipes are blocked]
When the toilet is stopped up, caused mainly by paper diapers, cloths, sanitary items, tissue paper, etc., use a plunger to try and solve the problem.
When your kitchen sewage pipes are blocked, you should check the elbow of the pipe under the sink and your outdoor drain pipe box, as kitchen refuse, hard objects, such as chopsticks and spoons, and hairs may be causing the blockage. The use of electric garbage disposals is not recommended.
If you let used cooking oil flow into your drain pipe, the oil could stick to the pipe and stay there, causing sewage blockage, in which case you should contact the plumbers appointed by the City to clear the pipe(s), as special tools will be required.
Improper use of drainage and sewage erage facilities may cause failure of the system, resulting in early deterioration of the system.
If you notice any blockage in a public sewage pipe, please contact the Sewer Division.
