312.4(B) Each system of buried ferrous piping used for either potable water or gas supply shall have a protective coating of an approved type, machine applied and conforming to recognized standards. Field wrapping shall provide equivalent protection and is restricted to those short sections and fittings necessarily stripped for threading.
312.4(C) All buried ferrous piping shall be provided with cathodic protection installed according to Table 312 of this Section and the following requirements:
1. Galvanic anodes for cathodic protection of ferrous piping shall be buried not less than 3 feet below grade and below the bottom of the pipe to be protected. They shall be not less than 4 feet horizontally from any buried metallic pipe. Before back filling, the anode shall be flooded with a minimum of 5 gallons of water.
When connected to the pipe being protected, less than 6 inches above grade, the anode shall be connected with a thermite weld. Connections 6 inches or more above grade may be made by the use of a listed mechanical clamp.
2. Water supply piping shall be isolated at the connection of the utility or private tap from the water main and at each building foundation line adjacent to the full-way shutoff valve.
