This is a recent version of a PVC ram pump that I first developed in about 1991. It is very low profile to avoid damage during high water, and can run under water 24/7 since the air is separated from the water in the air chamber - no need for a snifter valve. This pump can raise water to a height at least 15 times the fall (drive head). Of course, the output tapers off the higher you pump. All of the components are very simple and inexpensive but have proven themselves over millions of cycles. This particular installation is to feed two slow sand filters under test in the house in the background. (See my other Ram Pump video for the updated version of this pump)
