A. Building sewers serving buildings with a basement shall, whenever possible, be brought to the building at an elevation below the basement floor. In all buildings in which any building drain is too low to permit gravity flow to the public sewer, sanitary sewage carried by the drain shall be lifted by approved means and discharged to the building sewer. Backflow devices shall be installed in all building sewers serving new buildings with basements or new sewers serving existing buildings with basements, and the cost will be borne by the owner.
B. If an existing plumbing outlet or fixture has been installed or is planned to be installed at an elevation or location which could cause the outlet or fixture to overflow by reason of backflow from a main line sewer, a backflow prevention device of a type approved by the city shall be installed between the outlet and the public sewer in a manner as to prevent sewage from flowing back into the outlet or plumbing fixture. The property owner shall be responsible for installation and maintenance of backflow prevention devices.
C. If the property owner fails to install a backflow prevention device or maintain it in good working condition when required to do so by this code or other rules, regulations and charges governing water and sewer service, the city may order and require the plumbing fixture to be disconnected and removed and the outlet be plugged or capped.
D. The city shall not be held responsible for any property damage or other costs caused by plumbing outlets or fixtures located in violation of this section or by improperly installed or maintained backflow prevention devices.
