Susan the answer for 6.6.7 you said is correct is: “To relieve gas pressure buildup below the diaphragm in case the diaphragm develops a leak” and I when I first took this test I had chosen that one also and got it wrong. The definition provided for the Leak Limiter screw says: “Leak Limiter Screw is there in case the diaphragm develops a leak.” And that was the answer I gave on my second attempt and still got it wrong.
So the correct answer is what?
