<br />DWELLING HOUSE CODE
<br />102
<br />when poured against a dry surface shall have
<br />a bond of not less than 100 pounds per square
<br />inch. All surfaces of the joint shall be
<br />cleaned and dried before pouring. The com-
<br />pound shall not soften sufficiently to destroy
<br />the effectiveness of the joint when subjected
<br />to a temperature of 160 F nor be soluble in
<br />any of the waste carried by the drainage
<br />system. Approximately 25°fo of the joint
<br />space shall be filled with jute or hemp. A
<br />pouring collar, rope or other device shall be
<br />used to hold the hot compound during pour-
<br />ing. Each joint shall be poured in one opera-
<br />tion until the joint is filled. Joints shall not
<br />be tested until one hour after pouring.
<br />1593.15 Pre-cast joints.
<br />Pre-cast collars shall be farmed in both
<br />the spigot and bell of the pipe in advance of
<br />use. Collar surfaces shall be conical with
<br />side slopes of 3° with the axis of the pipe and
<br />the length shall be equal to the depth of the
<br />socket. Prior to making joint contact, sur-
<br />faces shall be cleaned and coated with sol-
<br />vents and adhesives. When the spigot end
<br />is inserted in the collar, it shall bind before
<br />contacting the base of the socket. Material
<br />shall be inert and resistant to both acids and
<br />alkalies.
<br />1593.16 Brazed joints.
<br />Brazed joints shall be made in accordance
<br />with the provisions of Section 6 of the Code
<br />for Pressure Piping, ASA B31.1.
<br />1593.17 Cement mortar joints.
<br />A layer of jute or hemp shall be inserted
<br />into the base of the joint space and rammed
<br />to prevent mortar from entering the interior
<br />of the pipe. Jute or hemp shall be dipped into
<br />a slurry suspension of portland cement in
<br />water prior to insertion into bell. Not more
<br />than 25°Jo of the joint space shall be used for
<br />jute or hemp. The remaining space shall be
<br />filled in one continuous operation with a
<br />thoroughly mixed mortar composed of one
<br />part cement, and two parts sand with only
<br />sufficient water to make a damp mixture
<br />workable by hand. After one-half hour of
<br />setting, the joint shall be rammed around
<br />its entire periphery with a blunt tool to force
<br />the partially stiffened mortar into the joint
<br />and to repair any cracks formed during the
<br />initial setting period., Pipe interior shall.be
<br />swabbed to remove any material that might
<br />have fallen into the interior. Additional
<br />mortar of the same composition shall then
<br />be troweled so as to form 45° taper with the
<br />barrel of the pipe.
<br />1593.18 Burned lead joints.
<br />Burned (welded) lead joints shall be
<br />lapped and the lead shall be fused together
<br />to form a uniform weld at least as thick as
<br />the lead being joined,
<br />1593.19 Asbestos-cement sewer pipe joints.
<br />Joints in asbestos cement pipe shall be
<br />made with sleeve coupling of the same com-
<br />position as the pipe, sealed with rubber
<br />rings. Joints between asbestos-cement pipe
<br />and metal pipe shall be made by means of an
<br />adapter coupling calked as required in Sec-
<br />tion 1593.09.
<br />1593.20 Bituminized fiber pipe joints.
<br />Joints in bituminized fiber pipe shall be
<br />made with tapered type couplings of•the
<br />same material as the pipe, sealed with hot-
<br />poured jointing compound specified in Sec-
<br />tion 1593.14. Joints between bituminized
<br />fiber pipe and metal pipe shall be made by
<br />means of an adapter coupling calked as re-
<br />quired in Section 1593,09,
<br />1593.21 Special joints.
<br />(a) Copper tubing to screwed pipe joints.
<br />Joints from copper tubing to threaded pipe
<br />shall be made by the use of brass converter
<br />fittings. The joint between the copper pipe
<br />and the fitting shall be properly sweated or
<br />soldered, and the connection between the
<br />threaded pipe and the fitting shall be made
<br />with a standard pipe size screw joint.
<br />(b) Brazing or welding. Brazing or weld-,
<br />ing shall be performed in accordance with
<br />standards of practice approved by the Build-
<br />ing Official.
<br />(c) Slip joints, In drainage and water
<br />piping, slip joints may be used only on the
<br />inlet side of the trap or in the trap seal, and
<br />on the exposed fixture supply.
<br />(d) Ground joint b r a s's connections.
<br />Ground joint brass connections, which allow
<br />adjustment of tubing but provide a rigid
<br />joint when made up, shall not be considered
<br />as slip joints.
<br />(e) Expansion and contraction. Provision
<br />shall be made for expansion and contraction
<br />of piping and for structural settlement that
<br />may affect the piping.
<br />1593.22 Unions.
<br />(a) Drainage system. Unions may be used
<br />in the trap seal and on "the inlet side of the
<br />trap. Unions shall have metal to metal seats.
<br />(b) Water supply system. Unions in the
<br />water supply system shall be metal to metal
<br />with ground seats.
