[Amended 12-2-1987 by L.L. No. 11-1987]
All connections from building to street sewers shall be made by a licensed plumber after obtaining a permit from the Code Official. All work shall remain uncovered until approved by the Code Official.
A. 
Each building shall be separately and independently connected with a public or private sewer or a cesspool or septic tank, except where a building is located on the rear of the same lot with another building when, if sewer connected, its plumbing and drainage system may be connected to the house drain of the front building behind the house trap and fresh air inlet, and, if not sewer-connected, such rear building may be connected to an existing cesspool of the front house if provided with a separate house trap and fresh air inlet. All sewer connections from the public sewer in the street shall be four-inch extra-heavy cast-iron pipe. All joints shall be caulked with lead. The joint at the main sewer between the tile and cast iron shall be carefully made with oakum and sewer seal poured hot. No bends shall be allowed. Cleanouts must be installed on the street side of the house trap. An iron running trap must be placed in the house drain near the front wall of the house and on the sewer side of all connections. Where fixtures are less than one foot above the main sewer in the street, an approved back water valve must be installed. The house sewer shall run in a direct line from the street sewer to the inside of the foundation wall with a Y and four-inch cleanout unless otherwise approved by the Plumbing Inspector.
B. 
Where the house trap and cleanout are placed below the cellar floor, they shall be enclosed in a masonry pit with cemented joints not less than two feet by two feet. The pit shall be fitted with a cast-iron cover not less than two feet by two feet set flush with the floor, and the cover shall be fitted with one or more ring handles. The pit shall be left clean of all forms, concrete or rubbish.
C. 
Where sewer connections are being made to an existing building with unvented fixtures, nonsyphoning traps may be installed on existing fixtures by special permission of the Plumbing Inspector.
D. 
No double hub or double T's shall be used on soil or wastelines. Drilling or tapping of house drains or soil or waste or vent lines or the use of saddle hubs or straps is prohibited.
Every building must have its sewer connection directly in front of the building unless permission is otherwise granted by the Plumbing Inspector.
Cesspools or septic tanks shall be permitted only after it has been shown to the satisfaction of the Board of Trustees or such agent as it may appoint for that purpose that their use is absolutely necessary and, when permitted, must be as approved by the Health Department. As soon as a public sewer is available, the owner must have the cesspool and privy emptied, cleaned and disinfected and filled with fresh earth and have a sewer connection made in the manner herein prescribed.
Old house sewers can be used in connection with new plumbing only when they are found, on examination by the Plumbing Inspector, to be in good condition and then only when they are five-inch extra-heavy cast iron.
All materials must be of the best quality, free from defects, and all work must be executed in a thorough workmanlike manner.
A.
