Zodiac valve advice

[toe72]

Hi folks,
So I had a leaking valve last summer and I finally swapped out the little plunger valve in my 2001 zodiac open pro 650. It still hisses when I inflate it and lost probably half it's pressure over a week... Ugh. What do you think I should do? I was thinking of solutions like backing it out half a turn or two to better seat the diaphragm against the inside....not sure.

Anyone have an advice?

I did change the o ring as well on the male part of the cover....

Thanks

I noticed the line that said "Tuck the corners of the diaphragm..."

Maybe worth rechecking that?
