You can hardly detect the same flow rates on their video through relative sized the water stream. Keep in mind that a more open faucet valve increases actual throughput without helping the size in the stream. The stream dimension is usually constricted by the aperture on the pipe. When a 9.5 pH alkaline water from an Enagic Leveluk SD501 is showing an ORP measurement in the -100 to -200 milliVolt range (like the other competitor measurements), there just 3 leads to. First, the valve position is more open. Second, there was acid water in the chamber the day the test. Third, there is considerable scale deposits in the electrolytic appropriate slot.
