P-Valve Set Screw tightness

[jar546]

I have had an ongoing leak around the P-valve the last 4-5 dives. I do flush it out as recommended and noticed when I flushed it that there was some flush coming out of the hole in the set screw. If it is too loose, it appears to leak and I understand from reading other threads that it cannot be too tight or it will leak.

What exactly is a good tightness?


Maybe I am just due a rebuild.
My P-valve has been installed on this suit for about 7 months and has approximately 100 dives with the P-valve used every dive.

I was going to continue this thread but it is closed for some reason: http://www.scubaboard.com/forums/halcyon/373155-halcyon-p-valve-leak.html

I think my duckbill valve just needs to be replaced.

Here is a photo. It is always open with a gap in it and I would think it would be normally completely closed. Whaddya tink?

Yes, duckbill needs to be replaced. The split nut should be a bit proud when you run your finger around the valve. not 'threads visible' proud but a bit proud as opposed to inset.
