Note: For example, if a given length of main, including all fittings, valves, drip pots, etc., is a unit and the cost of such section of main includes the cost of the valves, drip pots, etc., no separate credit to the plant account shall be made when a drip pot or valve (the book cost of which is less than $50) is retired even though not replaced. Any labor in connection with the removal shall be charged to the appropriate maintenance account, and any salvage for material recovered shall be credited to the appropriate maintenance account.
