  • Jim the rubber comes in sheets and is used for showers under the tiles as a water barrier. It's about 1/16" thick.

    APC let me know what you come up with

  • Hi Ed. what is the blue material you made your flap valves from, some kind of rubber?

  • dirt fighter the 3" outlet might work but I haven't had any problems with the 2"

    APC, maybe if you seal off the top of the piston and have water pumped out on the up stroke

  • Hey Ed, I like your design. Do think it would be better for ease of use and flow if the exit side was also at 3" rather than reduced back down to 2" ? (also having 3" hose) 

  • store bought valves don't work well at all. This will move 1" minus gravel with ease.

    I made my own flapper valves with a 2" opening in them , see my other pics on the build up of this.

    Also i have not weighted mine and it works just fine.

    The whole reason this one has such good suction is I'm using a 3" piston over a  2" opening. So each stroke moves almost 1 gallon of water. Where as a 2" piston would only move about 1/3 of a gallon.

  • Hi guy,s --where did you buy the check valves ?     looked on e-bay , and they seemed kinda pricy .

  • Looks pretty good, Ed! Hope it works great for you!

  • Nice looking toy Ed.

  • the black thing is for hooking the hose to my sluice box

  • Whats the piece behind bucket hose?
