Pulse valve test update-
- Hard pluming the stand pipe, i only had 1 collar to work with, so i started at the lowest position the valve can go.
- i extended the screen box height to simulate the same water level. from input to out flow. ( manometer test ) sort of.
-First test the screen box water level was 2 " higher than pulse valve water level.
- second test , i lowered the screen box out flow to the same water level as the pulse valve.
-third test , long stand pipe., 34 " water level difference.
-Plumbed in a 1/4" hard plastic line (blue) to vacuum out air in pipe stand
-fourth test, manufactured a steel ring seat, with a narrow curved top ,to focus on a small surface area to seal against the diaphragm gasket.
-fifth test, changed the 3.3/4" valve stem disk to the original smaller disk, 1.13/16"
-also tried slipping different "O" rings, rubber disks, and a half rubber ball , under the valve stem disks. . Also different compression springs.
