Hi.. this is from a 1999 entry to a thread about electric pumps. To see the whole thread go to http://www.paddlewise.net/topics/boatequip/elecpumps.html Check valves: These permit water flow from the pump and prevent backflow. I used a modified 1/2 inch pvc valve designed for home plumbing systems. I decreased the opening pressure (200 psi) by unscrewing the spring cap, cutting the spring roughly in half, bending the cut tip to fit the cap, then putting it all back together. This cut the opening pressure acceptably, so that the valve did not appreciably slow the pump's outflow. *************************************************************************** PaddleWise Paddling Mailing List - Any opinions or suggestions expressed here are solely those of the writer(s).
