Water pumps are used for a variety of reasons --- to move water up a hill, out of the bilge of a boat, or from a low or hard-to-reach area such as a basement. When you can't let gravity move the water for you, build a simple hand pump out of inexpensive and commonly available parts. Access to electricity isn't necessary to make and use this suction pump.

Instructions

  1. 1

    Saw an 18-inch length of 1/2-inch PVC pipe and a 24-inch length of 1/2-inch wooden dowel.

  2. 2

    Cut three circles of craft foam to be just over 1/2 inch in diameter.

  3. 3

    Drill a hole in the centre of the end of the dowel and attach the craft foam circles with the screw and washer. This is your piston. Insert it into the 18-inch length of PVC pipe.

  4. 4

    Add a "T" PVC fitting to the end of the 18-inch pipe setting.

  5. 5

    Cut two 6-inch pieces of 1/2-inch PVC pipe and insert them into either end of the "T" fitting.

  6. 6

    Fit the check valves on either side of the 6-inch PVC pipe pieces.

  7. 7

    Add more pipe pieces, elbows and hoses to either end of the check valves based on your pumping needs.

Tips and warnings

  • If you want your pump to stay in one configuration, use PVC cement to attach the pieces together.
