<br /> <br />18 <br />Steel Suction Piping - 2-1/2" - One (1) Fire Type Swing-Out Valve <br />All piping on the suction side shall be made of steel (welded joints) painted red. The <br />suction piping, the pump and the discharge shall be tested to 400 PSI. <br /> <br />The suction piping shall consist of a 2-1/2" tank to pump line with a 2-1/2" flexible rubber <br />hump hose to minimize flex and vibration between the pump and the tank. <br /> <br />RIGID PIPING SHALL NOT BE ACCEPTABLE. <br /> <br />Between the tank and the pump there shall be a 2-1/2" fire type swing-out valve. This <br />valve shall remain open to pump from the tank. <br /> <br />This pipe shall have a tee into the suction side of the pump and shall continue to the rear <br />of the truck for overboard suction. <br /> <br />The overboard suction connection shall have a 2-1/2" NST male adapter and a 2-1/2" <br />NST-F cap with retaining cable. <br /> <br />To draft, the tank to pump valve shall be closed, a suction hose connected to the <br />overboard suction connection and placed in a static water supply, and the primer <br />activated. <br /> <br />Tank to Pump “T” Handle Control <br />Attached to the handle of the fire grade tank to pump valve shall be a "T" handle control / <br />rod that shall extend to the end of the pump platform to allow for ease of use to open / <br />close the fire grade tank to pump valve. <br /> <br />Steel Discharge Piping <br />All piping shall be steel piping or high-pressure flexible hose. A 2.5" X 2.5" square steel <br />manifold shall be piped directly to the discharge outlet of the pump. Attached to this <br />discharge manifold, by means of welded steel pipe nipples, shall be all the discharge <br />valves. All piping shall be painted red to match the pump. <br /> <br />The discharge shall be equipped with a drain valve at the lowest point. <br /> <br />1” Tank Fill <br />There shall be a 1" valve piped from the discharge manifold as a means for refilling the <br />tank and re-circulating water during stagnant pump operations. The valve shall be an <br />industrial quarter turn valve handle and 1" NPT threads, and shall be connected to the <br />tank fill port by 1" high pressure flexible hose. <br /> <br />One (1) 1-1/2" Discharge to Rear <br />There shall be one (1) 1.5" valve piped from the discharge manifold to the rear of the truck <br />for connection of forestry hose. The valve shall be a fire type quarter turn swing-out valve <br />with 1-1/2" NST threads. The valve shall be furnished with a 1-1/2" NST cap and chain. <br /> <br />One (1) 1" Discharge to Booster Reel <br />There shall be 1" valve piped from the discharge manifold to the booster reel. The valve <br />shall be a fire type quarter turn swing-out valve handle and 1" NPT threads and shall be <br />connected to the reel by 1" high pressure flexible hose. <br />
