pvc foot valves






    foot valves
  • A one-way valve at the inlet of a pipe or the base of a suction pump

  • (Foot Valve) A type of check valve with a built-in strainer. Used at point of liquid intake to retain liquid in system, preventing loss of prime when liquid source is lower than pump.

  • (Foot Valve) A special type of check valve located at the bottom end of the suction pipe on a pump; it opens when the pump operates to allow water to enter the suction pipe, but closes when the pump shuts off to prevent water from flowing out.

  • (FOOT VALVE) Part of the cylinder that holds the column of water in the rising main while the plunger is being pushed down after each up-stroke.

Mini Baking Soda Gun




Mini Baking Soda Gun





This is one of the smallest baking soda and vinegar gun I've ever built. It's only 5 3/8 inches long and shoots 1/2 inch rubber stoppers. For fuel, it uses 2 teaspoons of vinegar and 1/2 teaspoon of baking soda per shot. This gun is able to shoot rubber stoppers at speeds of more than 90 feet per second with as much as 1.33 foot pounds of impact force. That's more impact force than a Red Ryder BB gun! In one more recent test, the gun was able to launch an extra-tight fitting rubber stopper at 125 feet per second with a force of about 2.35 foot pounds! The gun is constructed from a 1/2 inch threaded PVC end cap, a 2 inch long section of threaded PVC pipe, a threaded 1/2 inch PVC ball valve, and a 1 1/2 inch long section of threaded PVC pipe. Plenty of teflon thread tape was used to make the joints as tight as possible. Construction cost is aproximately $6.00 For an even smaller gun, see World's Smallest Baking Soda Gun.
