    What is the valve number of the NRS big river tube, I lost a couple and need to replace them
    Thanks you!

      Carole, the valves are Item # 38543.01. Note there are two models of the valve, pre-April 2009 and post-April 2009. There's a slight difference in the diameter of the valve threads; find those measurements in the Specs tab. Measure what you've got to be sure you're getting the right valve.

      Most of our hand pumps will work. The most economical are the Wonder Pump 6 and the Bravo 2 Foot Pump.

      Well, the tube will carry the weight, but I can't predict your comfort level! the center of the tube is 20" in diameter.
