13.28.220 Joints and gaskets:

All joints and connections shall be made gastight and watertight.

A.    Cast iron pipe joints shall be firmly packed with oakum or hemp and filled with molten lead, Federal Specification (QQ-L-156), not less than one inch deep. Lead shall be run in one pouring and caulked tight. No paint, varnish, or other coatings shall be permitted on the jointing material until after the joint has been tested and approved.

B.    All joints in vitrified clay pipe or between such pipe and metals shall be made with approved hot-poured jointing material (CPl-2 or equal) or cement mortar as specified below.

1.    Material for hot-poured joints shall not soften sufficiently to destroy the effectiveness of the joint when subjected to a temperature of one hundred sixty degrees Fahrenheit, nor be soluble in any of the wastes carried by the drainage system. The joint shall first be caulked tight with jute, hemp, or similar approved material.

2.    Mortar joints for bell and spigot sewer pipe shall consist of a mixture of one part by weight portland cement to one and one-half parts by weight sand and twentyfive pounds of "Embeco" to each sack (ninety-follr pounds) of portland cement. To the above ingredients thoroughly mixed dry, sufficient clean water shall be added to dampen the mixture so that it will just hold a ball when compressed in the hand.

C.    Gaskets for concrete or vitrified sewer pipe joints shall be oakum dipped in neat portland cement grout and of sufficient length to reach entirely around the pipe. Care shall be taken that no loose ends or fibers of the gasket material are allowed to protrude from the joint and that four-fifths of the depth of the socket is left for the joint mortar. As soon as the gasket is caulked and the pipe secured against movement, the remaining annular space in the pipe bell shall be filled by caulking the mortar specified hereinbefore, with a hardwood stick. Other jointing materials and methods may be used only by approval of the city engineer. (Ord. 47 §411, 1953).

13.28.230 Connecting building and public sewer--"Y" branch.

The connection of the building sewer into the public sewer shall be made at the "Y" branch, if such branch is available at a suitable location. If the public sewer is twelve inches in diameter or less, and no properly located "Y" branch is available, the owner shall at his expense install a "Y" branch in the public sewer at the location specified by the building inspector. Where the public sewer is greater than twelve inches in diameter, and no properly located "y" branch is available, a neat hole may be cut into the public sewer to receive the building sewer, with entry in the downstream direction at an angle of about forty-five degrees. A forty-five degree ell may be used to make such connection, with the spigot end cut so as not to extend past the inner surface of the public sewer. The invert of the building sewer at the point of connection shall be at the same or at a higher elevation than the invert of the public sewer. A smooth, neat joint shall be made, and the connection made secure and watertight by encasement in concrete. Special fittings may be used for the connection only when approved by the building inspector. (Ord. 47 §412, 1953).

13.28.240 Connecting building and public sewer--Inspection.
