3.2 Definitions of Terms Specific to This Standard:
3.2.1 adhesive/sealant—an elastomeric bonding agent designed to provide a water activated, leak resistant flexible bond between
a PVC pipe saddle and a lateral sewer service pipe.
3.2.2 borehole —a small diameter vacuum excavated hole.
3.2.3 cleanout—a fitting located on a lateral sewer service pipe having a vertical riser pipe extending therefrom to the surface
providing access to the lateral sewer service pipe.
3.2.4 cleanout riser pipe—a section of pipe that is connected to the boss of a saddle and extends from the saddle to the surface.
3.2.5 coring—the process of remotely cutting a hole through the crown of a sewer service pipe such that the coupon is retrieved
to establish communication from a cleanout riser pipe and a lateral sewer service pipe.
3.2.6 coupon—a disc shaped piece of the lateral sewer service pipe produced by coring.
3.2.7 lateral sewer service pipe—a sewer pipe that connects a building to a municipal, main sewer pipe in a lateral direction and

extend beyond the spring line of the host pipe. The saddle includes setoff tabs that allow for uniform distribution of the
adhesive/sealant.
3.2.9 setoff tabs—Protruding tabs located on the underside of the saddle one located on each side of the saddle boss for the purpose
of insuring a specific annulus between the host pipe and the saddle and a specific layer thickness of adhesive/sealant.
3.2.10 sonde—a device outfitted in a closed circuit video inspection camera that emits a signal in subterranean pipelines that is
traceable by use of a locating receiver at surface.
4. Summary of Practice
4.1 The process of installing a cleanout through a minimally invasive excavation begins with locating the 4 in. or 6 in. sewer
service lateral. This is accomplished by use of a CCTV outfitted with a locatable sonde and vacuum excavating a small borehole,
providing access to the exterior surface of a lateral sewer service pipe. Once the lateral sewer service pipe has been exposed, a
self-clamping saddle is prepared by applying a specified amount of adhesive/sealant to the underside of the saddle and a riser pipe
is attached to the boss of the saddle. The prepared saddle is lowered into the small diameter bore hole until it contacts the lateral
sewer service pipe; a downward force is applied to the riser pipe causing the side walls of the saddle to spread and encompass more
than 50-percent of the host pipe. Surface restoration is minimal and in most cases is accomplished the same day the cleanout is
installed.
5. Significance and Use
5.1 This practice is for use by designers and specifiers, regulatory agencies, owners, and inspection organizations who are involved
in the installation of a sewer service cleanout
6. Components
6.1 The saddle shall be formed as a semi-circle and shall encompass more than 180-degrees of the pipe circumference. The saddle
shall have an inner diameter equal to the outer diameter of the host pipe (see Fig. 1).
6.2 The riser pipe shall be PVC pipe in accordance with Specification D3034.
6.3 Adhesive/Sealant shall be in accordance with Specification C920.
