Foam Eductor Check
An in-line eductor only makes foam inside a narrow pressure window — too much back pressure from hose or elevation and it quietly stops drawing concentrate. Check the setup before the line is stretched, not after.
Blank assumes the required 200 psi.
Must match the eductor rating — a mismatched or partially-closed nozzle kills the draw.
Blank means level. Negative means the nozzle is below.
Enter values above to see the result.
