Purchased the flow indicator pictured below for a simple easy set up, plus it looked neat. Was very disappointed that the inside spiral will not turn with the typical HY pumps.
Fortunately, it will unscrew, and from my wife’s sewing room pilfered some light ribbon. The ribbon moves just enough to tell me the liquid is flowing. Posting to hopefully save someone the same fate, in addition it too expensive for what it is.
Are the paddle wheel indicators working well with the classic type pumps? Photos? Thanks…
