Foreword

This foreword is for information only and is not a part of AWWA C800.

I. Introduction.

I.A. History. In 1929, the development of a standard for threads for

underground service fittings was undertaken by the American Standards Association

(ASA). In 1932, the subcommittee that had been appointed for the task asked to be

discharged after it had submitted its proposed standards in the form of two drawings.

No action was taken by ASA on these proposed standards.

The American Water Works Association (AWWA) recognized the need for

standardization of these threads and appointed a committee in 1940 to prepare a

standard. The New England Water Works Association (NEWWA) also appointed a

committee to prepare a standard for these threads. The AWWA and NEWWA

committees cooperated closely in developing a tentative standard in 1947. This was

approved as a standard by AWWA on Sept. 1, 1948, and by NEWWA on Sept. 14,

1948. Revisions to the standard were made effective Jan. 17, 1955. In July 1963, a

committee was formed to revise C800-55 regarding to the evaluation of types K and

L copper tubing for water services. In the revision, published in 1966, threads

representing current practice were established for those fittings generally used in the

water utility field. Sizes 1/2 in. and 5/8 in. were added for inlet and outlet threads for

fittings and couplings for use with flared copper service tubing. The 1966 revision

introduced an appendix that was not part of the standard, but which listed standards

for water service line materials. The appendix was provided for information only

because the materials were covered by other standards. The appendix also contained

specifications for copper water tubing, red brass pipe, cast-iron pipe, and steel pipe.

In 1974, a standing committee was formed to revise and update C800-66. The

committee recognized the need to expand the scope of this standard beyond being a

standard covering only threads for underground service fittings. All previous versions

of C800 covered only the threads for fittings that were in common use in water

distribution systems. Subsequently, the scope of the standard was changed to include

performance standards for underground service line fittings as well as for the

threads. The 1984 revision to C800 was approved by the AWWA Board of Directors

on Jan. 29, 1984. The 1989 revision to C800 was approved by the AWWA Board of

vii


Directors on Jan. 1, 1990. This revision was approved by the AWWA Board of

Directors on January 21, 2001.

I.B. Acceptance. In May 1985, the US Environmental Protection Agency

(USEPA) entered into a cooperative agreement with a consortium led by NSF

International (NSF) to develop voluntary third-party consensus standards and a

certification program for all direct and indirect drinking water additives. Other

members of the original consortium included the American Water Works Association

Research Foundation (AWWARF) and the Conference of State Health and Environ-

mental Managers (COSHEM). The American Water Works Association (AWWA) and

the Association of State Drinking Water Administrators (ASDWA) joined later.

In the United States, authority to regulate products for use in, or in contact

with, drinking water rests with individual states.* Local agencies may choose to

impose requirements more stringent than those required by the state. To evaluate

the health effects of products and drinking water additives from such products, state

and local agencies may use various references, including

1. An advisory program formerly administered by USEPA, Office of Drinking

Water, discontinued on Apr. 7, 1990.

2. Specific policies of the state or local agency.

3. Two standards developed under the direction of NSF, ANSI†/NSF‡ 60,

Drinking Water Treatment Chemicals—Health Effects, and ANSI/NSF 61, Drinking

Water System Components—Health Effects.

4. Other references, including AWWA standards, Food Chemicals Codex,

Water Chemicals Codex,§ and other standards considered appropriate by the state or

local agency.

Various certification organizations may be involved in certifying products in

accordance with ANSI/NSF 61. Individual states or local agencies have authority to

accept or accredit certification organizations within their jurisdiction. Accreditation

of certification organizations may vary from jurisdiction to jurisdiction.

*Persons in Canada, Mexico, and non-North American countries should contact theappropriate authority having jurisdiction.

Annex A, “Toxicology Review and Evaluation Procedures,” to ANSI/NSF 61 does

not stipulate a maximum allowable level (MAL) of a contaminant for substances not

regulated by a USEPA final maximum contaminant level (MCL). The MALs of an

unspecified list of “unregulated contaminants” are based on toxicity testing

guidelines (noncarcinogens) and risk characterization methodology (carcinogens). Use

of Annex A procedures may not always be identical, depending on the certifier.

AWWA C800-01 does not address additives requirements. Thus, users of this

standard should consult the appropriate state or local agency having jurisdiction in

order to

1. Determine additives requirements, including applicable standards.

2. Determine the status of certifications by all parties offering to certify

products for contact with, or treatment of, drinking water.

3. Determine current information on product certification.

II. Special Issues.

II.A. Lead Fittings. All references to lead fittings have been removed from

C800 and the attached appendices. The AWWA Standards Department has available

to users of C800, copies of C800-84 information that contains references to lead

fittings.

III. Use of This Standard. AWWA has no responsibility for the suitability

or compatibility of the provisions of this standard to any intended application by any

user. Accordingly, each user of this standard is responsible for determining that the

standard’s provisions are suitable for and compatible with that user’s intended

application.

III.A. Purchaser Options and Alternatives. The following items should be

included in the purchaser’s specifications:

Drinking Water System Components—Health Effects is to be required, in addition to

the requirements of the Safe Drinking Water Act. If this certification is to be

required, the purchaser’s specification shall read, “This product shall be certified as

suitable for contact with drinking water by an accredited certification organization in

accordance with ANSI/NSF Standard 61, Drinking Water Systems Components—

Health Effects.

3. The size and type of fitting or valve.

ix


4. Quantity required.

5. Type of inlet thread (Sec. 4.4).

quently used or installed with drilling or tapping machines, certain internal and

external size limitations are required for their proper use.

4.3.1.1 Minimum inside diameter. Unless otherwise specified by the pur-

chaser, the minimum inside diameter of the waterway through a corporation stop

shall be large enough to accommodate the drill sizes shown in Table 1.

4.3.1.2 Overall body dimensions. For corporation stop to be installed by a

tapping machine, overall body dimensions shall conform with the dimensions listed

in Table 2.



.

4.3.2 Curb stops. Curb stops may be of an angle design or straight-through

design and shall provide a drip-tight shutoff in the closed position. The stop head

shall be of the tee design or flat design unless otherwise specified by the purchaser.

4.3.3 Service saddles. The service saddle shall have a body with a threaded

outlet, seal, and suitable means for attachment to the main. The body shall be made to

conform to the outside configuration of the main. The service saddle shall be designed

to provide a drip-tight connection when used as a service connection to the main.*

APPENDIX B

Field Testing

This appendix is for information only and is not a part of AWWA C800.

If purchasers choose to conduct field tests, the following recommendations are

available for general information.

SECTION B.1: FIELD TESTS

Field tests by the purchaser shall be in accordance with the pressures specified

in Sec. 4.2.2 or 4.2.3 as appropriate. External leakage through the valve body is not

allowed. The corporation outlet may be capped to eliminate leakage through the

closed valve’s port opening.

If higher test pressures, not to exceed 150 percent of the pressure rating, are

required, it is recommended that corporation stops be capped and tested in the open

position.

When testing a water main, if capping the corporation stop is impractical, the

recommended alternative is to test to the curb stop with the corporation stop open.

It is recommended that pressure testing of service lines be done before

backfilling to detect and facilitate the repair of any leaks at the joint or from the pipe,

valves, or fittings.
