Make ANY Water Pump Variable Speed - Pond, Sluice Box, Water Feature 

In this video I describe how you can turn any single speed water pump into a variable speed (or variable flow) water pump. In this example I show how I turned my 3000 GPH (Gallons Per Hour) water pump into variable speed with two techniques. One technique involves using an electronic variable controller, and the other involves using a split flow design with PVC pipe and PVC fittings. Through these methods you can control the rate of water flow.
