"The 1st product he made that I lost in the lake was from over tightening the hold down screws used on hand hole cover on the jet."
Or was it a design defect?
"Jim Brock both gave me some larger diameter screws to hold down the POP-OFF
Why not recommended standard?
"The pop off works fine if you stay on top of the plastic hose ends in the fittings. The main reason why the pop off engages premature is that the system looses air pressure because the hose ends are not pushed in the fittings or cut square and air loss occurs valve open"
Plastic hoses? If pressure critical, I'm thinking why not a secure connection not subject to small installation errors? Is this not an important safety item...life critical? As others have posted...dumb design. At the least not mature and badly needing refinement.
