SP-116

FOREWORD In the mid 1990’s, the Manufacturers Standardization Society was requested to develop a Standard Practice for line valves and assigned this as a project to the MSS Committee 112, Water Works Valves and Fittings. Many of the significant components of service-lines for drinking water systems have not been specifically covered by standards. The MSS Committee 112 decided to fill this need in the water works industry by creating this Standard Practice, which has a broader scope than previous drinking water service line standards. However, the tubing, pipe, water main, water meter, and machines associated with drinking water service-lines are not covered by this Standard Practice. Field testing information is provided in Section 6.4 but is not a normative part of this Standard Practice. The 2003 version was substantially revised from the original 1996 version. This 2011 version has been substantially updated and revised from the 2003 version; including an update of Sections 2, 4, 9, multiple Tables, and Annex A.

STANDARD PRACTICE 5.8.1 Check Valve Installation Because check valves must be periodically inspected to ensure that they are functioning properly and be repaired or replaced as needed, they must be installed only in non-buried service in an area easily accessible for service. The most common location is near the exit end of the water meter.

The seal shall be made of a resilient rubber material. The seal shall be attached to the inlet of the service clamp prior to shipment. A service saddle clamp shall fully encircle the main pipe and shall be designed so it does not damage the pipe. 5.9.1 Outlet Service saddle clamps shall each have one threaded outlet with tapered internal threads corresponding to standard AWWA internal threads for service saddle clamps as in Table 14 or to NPS threads complying with ASME B1.20.1 for standard pipe threads. The outlet height measured from the outer surface of the main pipe shall not exceed 2 inches so as not to exceed the available travel of drilling machines.

5.8.2 Check Valve Repair Check valves shall be field repairable without disconnecting the service-line or removing the valve body from the service line. 5.8.3 Moving Parts There shall be no noticeable vibration or chatter when the valve is at the full open position under flow conditions. 5.8.4 Closure Members Check valve closure members shall be spring assisted to close and shall resist opening and maintain a tight seal at 1 psi pressure in the direction of flow.

The maximum outlet size shall be one NPS smaller than the main pipe size. 5.9.2 Sizes of Service Saddle Clamps This Standard Practice only covers service saddle clamps made to attach to main pipes ranging from NPS 1⁄2 to 2. The manufacturer must designate the main pipe O.D. range for which the clamp is designed to be used.

5.8.5 Seats Check valve seats shall be comprised of one hard seat and one soft seat mating together to form a seal. Soft seats shall be made of a non-toxic rubber material suitable for this type of service. Hard seats and/or closure members and guides shall be made from ASTM B584 copper alloy C83600 or acetal plastic.

5.9.3 Types of Service Saddle Clamps and Materials Service saddle clamps vary by the type of material of which they are constructed; by the way they engage the pipe, by the main pipe O.D. range and type of main pipe they can be used with, and by the working pressure rating. These factors should be clearly indicated in the manufacturer's catalog information and selected and specified by the purchaser. This is especially important when the clamp is to be installed on pipe made of brittle material. Service saddle component materials shall be compatible to not promote galvanic corrosion.

5.8.6 Springs Check valve springs shall be made from stainless steel as specified in Section 4.5. Other check valve materials shall be as specified in Sections 4.1, 4.2, 4.3, and 4.8.

--`,`,`,`,,``,`````,`,`,,``,,,,,-`-`,,`,,`,`,,`---

5.9 Service Saddle Clamps Service saddle clamps are a fitting that attaches circumferentially around a pipe providing a tight seal and connection with an internal threaded outlet for the connection of a corporation valve, service fitting, or service-line pipe.

5.9.3.1 “Bronze” Service Saddle Clamps When designated as “bronze”, all metal components of a service saddle clamp shall be made of copper alloys as specified in Section 4.3.

The structural strength of service saddle clamps shall be adequate to maintain the seal under the normal conditions of the system water pressure and the soil induced stresses.

STANDARD PRACTICE

interchangeability of parts with units of the same size and model.

5.9.3.2 “Iron” Service Saddle Clamps When designated as “iron”, the outlet saddle shall be made from materials specified in Section 4.4, and the attachment straps and fasteners shall be zinc plated. Carbon Steel is specified in Section 4.6, and Stainless Steel specified in Section 4.5, or low alloy steel as per AWWA C111/A21.11.

6.2 Valves and fittings shall be free of metal chips and filings and excess lubricant in the waterway. Castings shall be clean and sound and without defects that could impair their service and shall be free of imperfections and defects which may be injurious to the performance of the valve.

5.10 Meter Setting Fittings and Equipment 5.10.1 Meter Settings Fitting Equipment Meter setting fittings and equipment shall provide a mating connection which structurally attaches and seals with a gasket to standard water meters that have meter casing spud ends on meters sizes NPS 5⁄8 through 1 (dimensioned as in Table 12), and meter flanged (oval) ends on meter sizes NPS 1½ and 2 (dimensioned as in Table 13), and meter lengths (dimensioned as in Tables 12 and 13).

6.3 Products manufactured to this standard are subject to inspection at the plant and approval by the purchaser. 6.4 Field testing is not a part of this Standard Practice and is not required. Should the purchaser choose to conduct field tests, the following supplemental recommendations are for general information: Field tests by the purchaser should be in accordance with the pressures specified in Section 5, 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.

5.10.2 Meter setting equipment shall be designed to allow easy removal and replacement of the water meter. Meter setting equipment shall remain rigidly in place when the water meter is removed and shall not rely on the water meter for structural strength or induce large forces to the body of the meter which may cause the meter to distort or malfunction.

--`,`,`,`,,``,`````,`,`,,``,,,,,-`-`,,`,,`,`,,`---

If higher test pressures not exceeding 150% of the pressure rating are required, it is recommended that metal seated corporation valves be capped and tested in the open position. For service saddle clamps attached to plastic pipe, the test pressure shall not exceed 150% of the pressure rating of the lowest rated component.

5.10.3 Materials Meter setting fittings and equipment materials, which are in contact with the drinking water, shall be as specified in Sections 4.1, 4.2, 4.3, 4.7, and 4.8 of this Standard Practice, except for copper tubing which shall comply with ASTM B88 Type K or ASTM B75.

When testing a water main, if capping the metal seated corporation valve is impractical, the recommended alternative is to test to the curb valve with the metal seated corporation valve open.

Structural components of meter setting equipment, which are not in contact with the drinking water, shall be made of materials specified in Sections 4.1, 4.2, 4.3, 4.4, 4.5, 4.6, 4.7, and 4.8, as appropriate, for long term service in the anticipated corrosion environment.

Pressure testing of service-lines should be done before backfilling to facilitate the detection and repair of any leaks. A purchaser who intends to use or test serviceline valves and fittings at pressures in excess of those stated in this Standard Practice should never exceed 150% of the rated pressure.

6. INSPECTION AND TESTING 6.1 All valve parts shall be made within inspection limits that will ensure ready

9. INSTALLATION

6.5 The manufacturer shall 100% factory test all valves and fittings except service saddle clamps to meet the pressure requirements as outlined in Section 5, and they shall be drip tight for a minimum of 5 seconds.

9.1 The performance of products depends on proper installation. The purchaser should follow instructions supplied by or available from the manufacturer. If these instructions are not available, good installation practices shall be followed.

6.6 Unless the terms of the sale were otherwise stated in the purchaser's specifications, the purchase contract or the manufacturer's warranty, any service-line valve or fitting that the purchaser rejects as not conforming to this standard shall be returned to the manufacturer. If the valves or fittings are found defective, they shall be replaced with new valves or fittings at the manufacturer's expense.

9.1.1 All instructions supplied by the manufacturer should be reviewed in detail before installation of service-line valves and fittings. It is recommended that new servicelines be flushed prior to installing the water meter. A spool piece of a length matching the meter to be installed should be used in place of the meter when flushing is performed. 9.1.2 Electrical grounding to the water piping system should be avoided if possible. AWWA opposes the grounding of electrical systems to pipe systems conveying drinking water to a customer's premises(1).

7. MARKINGS 7.1 All valves shall be legibly marked in accordance with the requirements of MSS SP-25.

However, it must be recognized that many pipe systems continue to be used as a grounding electrode system.

7.2 All check valve and other one-way valve bodies shall be legibly marked to indicate the direction of flow by means of an arrow cast on the valve body or the word “in” or “inlet” cast or stamped on the inlet end of the body.

Section 250.53(D)(1) of NFPA 70, the National Electrical Code (NEC), requires that “continuity of the grounding path or bonding connection to interior piping shall not rely on water meters”. Most utilities require permanent ground strapping around meters to prevent accidents to workers changing meters. All meter settings should be permanently ground strapped.

7.3 The manufacturer's name or trademark shall appear on the body of valves and fittings. When appropriate and possible, it is recommended that markings on valves also include size and pressure rating. 7.4 Service saddle clamps shall be marked with the manufacturer's name or trademark, main pipe O.D. range, outlet size, and type of outlet thread. 8.
