Stormwater shall not drain into the sanitary sewer system of the Village.
Floor drains and sumps in basements and cellars of residence buildings shall not be drained into the sanitary sewer system.
Old house sewers may be used in connection with new buildings or new plumbing only when they are found on examination by the Plumbing Inspector to conform in all respects to the requirements governing new sewers.
All house sewers shall be constructed of five-inch extra-heavy cast-iron pipe. Each length of pipe and all cast-iron fittings shall have size and weight cast upon its exterior surface. Such pipe, including hubs, shall weigh not less than 17 pounds per linear foot. Cast-iron pipe and fittings shall not vary in any two diameters greater than 1%.
The house drain and its branches must be of extra-heavy cast iron when underground, and of extra-heavy cast iron or galvanized wrought iron or steel when aboveground.
The house drain must properly connect with the house sewer at a point two feet outside the outer front vault or area wall of the building by a fitting five inches in diameter, leading out for connection. An arched or other proper opening must be provided for the drain in the wall to prevent damage by settlement.
The house drain, if above the cellar floor, must be supported at intervals of 10 feet by eight-inch brick piers or suspended from the floor beams or be otherwise properly supported by proper hangers placed not more than 10 feet apart.
No steam exhaust boiler blowoff or drip pipe shall be connected with the house drain. Such pipes must first discharge into a proper condensing tank, and from this a proper outlet to the house sewer outside of the building must be provided. In low-pressure steam systems the condensing tank may be omitted, but the waste connections must be otherwise as above required.
The house drain and house sewer must be run as direct as possible, with a fall of at least 1/4 inch per foot, all changes in direction made with proper fittings, and all connections made with Y-branches and one-eighth and one-sixteenth bends.
The house sewer and house drain must be at least four inches in diameter when receiving the discharge of a water closet. No house sewer or house drain shall be of less diameter than the largest line of pipe connected thereon. The following table is the maximum area allowed to drain into pipes of given diameter:

Full-size Y- and T-branch fittings for handhold cleanouts must be provided where required on house drain and its branches. No cleanout need be larger than six inches in diameter.
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, except that this shall not apply to a Y-fitting used to receive the discharge from an automatic sewage lift, oil separator or a drip pipe where one is used. If placed outside of the house or below the cellar floor, it must be made accessible in a brick manhole, the walls of which must be eight inches thick, with an iron or flagstone cover. When outside the house it must never be less than three feet below the surface of the ground.
When the plumbing system of any building is altered by the addition of a new soil or vent line to the extent of 50% or more and no house trap and fresh-air inlet exist on the house drain, same shall be prohibited.
The house trap must have two cleanouts with brass screw cap ferrules caulked in.
A. 
A fresh-air inlet pipe must be connected with the house drain just inside of the house trap and extended to the outer air, terminating with its open end at least one foot above the grade at the most available point, to be approved by the Superintendent of Buildings and shown on plans.
B. 
The fresh-air inlet pipe shall be 1/2 of the diameter of the house drain, but not less than four inches in diameter, and same must have a standard cup, perforated plate or a return bend.
The discharge from any fixture must first pass through the main house trap before entering outside sewer line, or it may pass through other lines, provided the traps connected therewith are approved first by the Superintendent of Buildings.
