Construction

1. Ream out one 3/4" male threaded PVC plug with a 3/4" hole for the 2' x 3/4" pipe and attach them.
2. Drill two 5/8" holes in the flat PVC cap and tap them to 3/4" for the air in and water out 3/4" male threaded PVC plugs. Use plumbers tape and attach the plugs. Glue the PVC cap to the 2' x 2" pipe.
3. Remove the spring of the metal check valve like in the hydromissions slapshot instructions.
4. Glue the 2" to 3/4" plug to the other end of the 2' x 2" pipe, attach the 3/4" male threaded coupler and the 3/4" check valve.
5. Attach the hoses to the plugs with plumbers tape and clamps and test the pump.
