A. General. This Section contains provisions applicable to joints specific to sanitary drainage piping. Provisions for those joining methods which are applicable to more than one piping system are contained in Chapter 3 of this code.

B. Caulked Joints. Caulked joints for cast-iron hub-and-spigot soil pipe shall be firmly packed with oakum or hemp and filled with molten lead not less than 1-inch (25.4 mm) deep and extending not more than 1/8 inch (3.18 mm) below rim of hub. No paint, varnish, or other coatings shall be permitted on the jointing material until after the joint has been tested and approved.

C. Joints for Plastic Pipe and Fittings. Refer to §313. H of this code for ABS and PVC joints.

D. Elastomeric Compression Gasket for Cast Iron Soil Pipe. Elastomeric compression gasketed joints for cast iron soil pipe shall comply with the following.

1. A positive-seal one piece elastomeric compression type gasket may be used for joining hub and spigot cast iron soil pipe as an alternate for lead or oakum joints. The joint is formed by inserting an approved gasket in the hub. The inside of the gasket is lubricated and the spigot end of the pipe is pushed into the gasket until seated, thus affecting a positive seal.

2. A positive-seal one piece elastomeric compression-type gasket for joining hub and spigot cast iron soil pipe may be used for drainage and waste systems above and below ground.

3. Compression gaskets for cast iron soil pipe shall be neoprene, marked as such, with ASTM C 564.

E. Hubless Cast Iron Soil Pipe System. Joints for hubless cast iron soil pipe shall comply with the following.

1. Joints for hubless cast iron soil pipe shall be made with an approved gasket and stainless steel retaining sleeve.

2. Stainless steel couplings and gaskets complying with standards listed in Table 303 of this code shall have identifying markers to indicate compliance.

3. Installation of the hubless cast iron soil pipe system shall be in accordance with CISPI 310 or the manufacturer's recommendation.

F. Borosilicate Glass Pipe. Joints for borosilicate glass pipe shall comply with the following.

1. Glass to glass connections shall be made with a bolted compression type stainless steel (300 series) coupling with contoured acid-resistant elastomer compression ring and a fluorocarbon polymer inner seal ring.

2. Joints between glass pipe and other types of piping material shall be made with adapters having a tetrafluoroethylene (TFE) seal and according to manufacturer's recommendations.

3. Caulked joints shall conform with §709. B of this code except that acid resistant rope and acid proof cement may be used.

G. Joints for Ductile-Iron Gravity Sewer Pipe (bell and spigot). Joints in ductile-iron gravity sewer pipe shall be of the push-on joint type using a single oil resistant gasket joint. The gasket and the annular recess in the bell end of the pipe will be designed and shaped so that the gasket is locked in place against displacement. The oil resistant gaskets shall conform to AWWA C111 or ANSI A21.11 and shall comply with the performance requirements of the standard.
