Section XIV-717 - Cleanouts

A. Material and Design. The bodies of cleanout ferrules shall conform in thickness to that required for pipe and fittings of the same material, and they shall extend not less than 1/4-inch (6.35 mm) above the hub. For new work, the cleanout plug shall be of heavy brass or plastic not less than 1/8-inch (3.18 mm) thick and shall be provided with a raised nut or a recessed socket for removal. Both ferrule and plug shall have ASME standard tapered pipe threads. Heavy lead plugs may be used for repairing a cleanout where necessary. Nylon plastics may be used as an alternate material.

B. Location. The location of cleanouts shall comply with the following:

1. Each horizontal drainage pipe shall be provided with a cleanout at the upstream end of the pipe and in changes of direction over 45° (0.785 rad).

a. Exceptions. The following plumbing arrangements are acceptable in lieu of the upstream cleanout:

i. "P" traps connected to the drainage piping with slip joints or ground joint connections;

ii. "P" traps into which floor drains, shower drains or tub drains with removable strainers discharge;

iii. "P" traps into which the straight through type waste and overflow discharge with the overflow connecting to the branch of the tee;

iv. "P" traps into which residential washing machines discharge;

v. test tees or cleanouts in a vertical pipe above the flood-level rim of the fixtures that the horizontal pipe serves and not more than 4-feet (1219 mm) above the finish floor;

f. cleanout within 6-feet (1829 mm) of the junction of the building drain and the building sewer which may be rodded both ways; and,

g. water closets for the water closet fixture branch only.

2. Each building drain shall be provided with a cleanout within 6-feet (1829 mm) of the junction of the building drain and building sewer.

3. Cleanouts when installed in accordance with §717. B.2 of this code may be either outside the building or when inside the building they shall be above the flood-level rim of the fixtures that the horizontal pipe serves when installed on a soil or waste stack.

4. In addition to the upstream cleanout and the cleanout of the junction of the building drain and building sewer, cleanouts shall be located along the horizontal piping so that:

a. In pipe 3-inch nominal diameter or less, cleanouts shall be located at not more than 50 ft (15.2 m) intervals; and,

b. In pipe 4 inches nominal diameter through 6 inches nominal diameter, cleanouts shall be located at not more than 80 ft (24.4 m) intervals.

C. Concealed Piping. C leanouts on concealed piping or piping under a floor slab or piping in a crawl space of less than 24 inches (610 mm) or a plenum of any depth shall be extended through and terminate flush with the finished wall, floor or grade_(G) or may be extended to the outside of the building. Where it is necessary to conceal a cleanout or to terminate a cleanout in an area subject to vehicular traffic, the covering plate, access door or cleanout shall be of the approved type designed and installed for this purpose.

D. Direction of Flow. Cleanouts shall be installed to permit cleaning in the direction of flow. Line cleanouts which may be rodded both ways shall be used whenever practical.

E. Use for New Fixtures Prohibited. Cleanout plugs shall not be used for the installation of new fixtures or floor drains, except where approved in writing by the plumbing official and where another cleanout of equal access and capacity is provided.

F. Trap Cleanouts. Cleanouts for traps shall comply with the following.

1. Each fixture trap, except those cast integrally or in combination with fixtures in which the trap seal is accessible, or except when a portion of the trap is readily removable for cleaning purposes, shall have an accessible brass trap screw of ample size. Cleanout plugs or caps shall be watertight and gastight. Nylon plastics may be used as an alternate material.

2. Cleanouts on the seal of a trap shall be made tight with threaded cleanout plug and approved washer. Where glass traps are required, slip joints or couplings must have a tetrafluoroethylene (TFE) seal.

G. Manholes. Sewer manholes shall be waterproofed, constructed of poured-in-place concrete or precast concrete pipe sections conforming to ASTM C 478. Bottoms shall be concrete poured on stabilized soil or aggregate subbase with inside surfaces sloped a minimum of 2 inches per foot to the pipe flow channel. All pipe connections and joints shall be sealed with approved waterstop or gasket materials and grouted. Manhole top frames and covers shall be Class 30 gray cast iron conforming to ASTM A 48/A 48M, machined for proper fit of covers in frame, coated with coal-tar pitch varnish and not less than 93 percent of the specified weight for each casting. Covers shall have the word "SEWER" cast in large letters. Similar, sealed covers with gaskets and cap screws or bolts shall be used where subject to flooding. See Figure 7 in Section 1807 of this code.
