Design Or production issues

I like the ease of removing the top but it seems to me that an obvious design flaw exists as I have had two valves now fail in the exact same way. With the valves leaking past the obvious solution was the diaphragm. Wrong! New diaphragms and no change. Changing the O-ring. Nope. Maybe the spring is too weak? Wrong again. The amount of time spent troubleshooting should be billed to you to find a small crack in the valve body in the exact same place on both valves. Having 10 of them it just makes me wonder if I should start replacing them with another brand knowing what is coming. Oh, and I had them about 2 years.
