LT Kepik spout flow diagram
Below 1.5 GPM the flow isn't noticeably different from that of the Kepik spout.
At 1.5 GPM the flow appears as a fairly smooth flat ribbon that breaks aparts the further it falls.
At 2.5 GPM a very faint whining noise reminiscent of a turbine can be heard. This may be installation dependent.
Beyond 4 GPM the sound is noticeable and is probably too obtrusive.
Spout was plumbed with 1 in pipe for all tests. Static line pressure was about 60 PSI. Since this spout relies on water pressure for to force the water out of the spout please consider this in your equipment selection.
