ND CNX flooding

[Shiro]

I bought a Northern Diver CNX -drysuit this May. The first 50 dives the suit worked perfectly, but now it has developed a rather peculiar problem. I had a three week break from diving, the suit stored in the closet. With no reason whatsoever the suit is flooding from the front. I suspect that the input valve is the reason. The water starts coming in gradually from 5 metres down. When pressing the button the sound of incoming air is somewhat "wet". I've examined the valve, theres no sign of trash or sand. The input hose has its O-ring in place.

Any tips, ideas, what can cause the leak?

Replace the o-ring and check for small bubbles near or around the valve.
