Public Works Department, Taipei City Government

When finding smells in the house, you need to check if the drainage is clogged; also check if the bath tub and washing basin are provided with a U-trap. An odor- preventing trap can also be installed in the floor drain, which also prevents insects and odor from coming back into the room. Check if the utility shaft that goes to the rooftop has been closed up; whether or not an independent shunt is provided for the toilet pipe. All the above items are issues in the internal piping and they shall be resolved by hiring a plumber. In case of clogging or smells from external pipes, please call 2596-8603 or fax to 2596-8672, or dial Taipei Citizens’ Hotline 1999 (02-27208889 from outside of Taipei City) to notify SSO for a joint process.
