(1) Calked joints. Calked joints for cast-iron bell-and-spigot soil
pipe ~ packed with oakum or hemp and filled ~vith molten
lead not less than 1 inch deep and not to extend more than 1/8 inch below

shall be used only on male threads.
(3) Wiped Joints. Joints in lead pipe or fittings, or between lead pipe
or firths a4d' ~rass or copper pipe, ferrules, solder nipples, or traps,
shall be full-wiped joints. Wiped Joints shall have an exposed surface
on each side of a joint not less than 3/4 inch and at least as thick as ~?~o
the material being jointed. Wall 'or floor flange lead-wiped joints shall

floor.
Joints between lead pipe and cast iron, steel, or wrought iron sha3_l

Joint shall be cleaned and dried before pouring. If wet surfaces are un-
avoidable, a s,~table prtmer shall be applied. Cempmmd shall not soften
sufficiently to destroy the effectiveness of the joint when subjected to
a temperature of 160° F. nor be soluble in any of the waste carried by
the drainage system. Approximately 25% cf the joint space at the base of
the socket sb~l ~ be f'~m!led with jute or hemp. A pouring collar, rope er
other device sh~l be used to hold the hot compound during pouring. Each
Joint shall be poured in one operation untLl the joint is filled. Joints
shall not be tested until one hour after pouring.
(7) Precas% Joints. Precast collars shall be for~ed in both the spigot
and b~l ~ KHe ~ipe in advance of use. Collar surfaces shall be conical
with side slopes of 3° with the axis of the pipe and the length sh$1~ be
equal to the depth of the socket. Prior to making Joint contact, sur-
faces shall be cleaned and coated with solvents and adhesives as recom-
mended in the standard, l~hen the .wpigot end is inserted in the collar,
it shall bind before contacting the base of the socket. Material s.hall
be inert and resistant to both acids and alkalies.
(8) Brazed Joints. Brazed joints shall be made in accordance with the
provi~'~'on~' of Sec~bion 6 of the Code for Pressure Piping, ASA B31.1-1~42
(with 1944 and 19~?~ Supplements).
(9) Cement Mortar Joints. Cement Joints shall be used only when spec~-
icall~ Permitted ~ Other Sections of this Chapter or when approved by
the A~ministrat£ve Authority. A layer of jute or hemp sha3~ be inserted
into the base of the joint space and rammed to prevent mortar from enter-
ing the interior of the pipe. Jmte or hemp shall be dipped 'into a slurry
suspension of portland cement in. water, prior to insertion into bell. Not
more than 25% of t.he joint space sba11 be used for jute .or h~. The re-
maining space shall be filled in one continuous operation with a thor-
oughly mix~i mortar cc~posed of one part cement and two parts sand, with

CH~'~PTF, R VIII, Page. 23
only sufficient 'water to make the mixture workable by hand.~ After one-
half hour of setting, the Joint 'Shall be rammed around entire periphery
with a blunt tool to 'force the partially stiffened mortar into the joint
and to repair any cracks formed during the initial setting period. Pipe
interior shall be swabbed to remove any material that might have fallen
into the interior. Additional mortar of the same composition shall then
be troweled so as to form a A5° taper with the barrel of the pipe.
(lO) Burned Lead .Jo'%nts~. Burned (welded) lead joiuts shall be lapped and
the lead shall be~ fused together to form a uniform weld at least as thick
as 'the lead being joined.

than 45 , the required diameter of the offset and the stack below it
shall be determined as for a building drain (Table 11.5.2).
(5) Offsets of more than 45°. A stack with an offset of more than 45°

(f) Covering _of Work.
(1) Requirements. No drainage or plumbing system or part thereof shall
be c°~e~ed until "it has been inspected, tested, and accepted as pre-
scribed in this Chapter.
(2) Uncovering. If any building drainage or plumbing system or part
thereof which is inst~led, altered, or repsdred, is covered before bet,~
inspected, tested, and approved, as prescribed in this Chapter, it shall
be uncovered for inspection after notice to uncover the work has been
issued to the responsible person by the Administrative Authority.
(g) Material and Labor for Tests. The equipment, material and labor nec-
essar~ ~or in~ec~io~n or 'te'~ts shall be furnished by the person to whom the
permit is issued or by whom inspection is requested.
(h) Tests of Drainage and Vent Systems. The piping of the plumbing, drainage
and venting sYStems -shall '~ ~es'ted' ~m"~h ~vater or air. After the plumbing
fixtures have been set and their traps filled with water, the entire drainage
system shall be submitted to a fi~! test. The Administrative Authority may
require the removal of an~ cleanouts~ to ascertain if the pressure has reached
all parts of the system.
(i) Methods of Testing Drainage and Vent Systems.
(1) Water Test. The water test shall be applied to the drainage system
eithe~ in its-entirety or in sections. If applied to the entire syste~
all openings in the piping shall be tightly closed, except the highest
opening, and the system filled with water to point of overflow. If the
system is tested in sections, each opening shall be tightly plugged ex-
cept the highest opening of the section under test, and each section
shall be filled with water~ but no section shall be tested with less than
a lO-foot head of water. In testing successive sections at least the
upper lO feet of the next preceding section shall be tested, so that no
joint or pipe in the building (except the uppermost l0 feet of the sys-
tem) shall have been submitted to a test of less than a 10-foot head of
water. The water shall be kept in the system, or in the portion under
test~ for at least 15 miuutes before inspection starts; the system shall
then be tight at all points.
(2) Air test. The air test s~.~ll be' made by attaching an air compressor
testing apparatus to any suitable opening~ and, after closing all other
inlets and outlets to the system, forcing air into the systez~nntil there
is a uniform gage pressure of 5 po~muds per square Lnch, or sufficient to
balance a column of mercury lO inches in height. Tl~is pressure shall be
held v~thout introduction of additional air for a period of at least 15
minutes.
(3) Final test. The final test of the completed drainage and vent ~ys-
tern m~Y be~ either a smoke ~est or a peppermint test. Where the smoke
