Small diameter r O secondary plumbing such as drain lines shall be stainless steel or brass. T r a Where vibration or chassis flexing may damage or loosen piping or where a coupling is LL required for servicing, the piping shall be equipped with victaulic or rubber couplings. L R Plumbing manifold bodies shall be stainless steel. a All lines shall drain through a master drain valve or shall be equipped with individual drain valves. All individual drain lines for discharges shall be extended with a hose to drain below 00MN r the chassis frame. Meets Exceeds Comments: U_ U)Ua Q. 212. MAIN PUMP INLETS A 6. 00" pump manifold inlet shall be provided on each side of the vehicle. The suction inlets shall include screens that are designed to provide cathodic protection for the pump, thus d 15 reducing corrosion in the pump. The main pump inlets shall have National Standard Threads with a long handle chrome cap. d The manufacturer shall also supply a gate valve for each inlet. Proposals shall list brand name, U type, and specifics of the proposed valves. R Q The cap shall incorporate a thread design to automatically relieve stored pressure in the line when disconnected. Meets Exceeds Comments: 213. VALVES All discharges shall use in -line ball valves. Valves shall have a ten ( 10) year warranty. Meets Exceeds Comments: Page 61 of 93 214.
