Cuff dump lets in water

[2wheeldiver]

anyone got any ideas?, I've suffered from an armfull of cold salty water for a while and I'm getting v tired of it. The water comes in through the cuff dump when I let air out. I've just fitted a brand new apex cuff dump and it does the same thing!!!! Are there other makes to try? I've had the same promlem with both undersuits, weezle extreme + Otter 200. Help!!!

Does it come though the dump centre or from around the side of the dump?

I only got wet when trying to dump when there was nothing left to dump on mine otherwise.

You could try blocking the dump with a folded plastic bag, fill the suit and spray soapy water to see if its round the side (in the same way you look for a suit puncture).

Only time I've had this problem has been due to either the outer part of the dump not being screwed down tightly enough, or there being a poor seal on the diaphragm either due to salt build up or grit getting trapped in there.

Don't have a thick undersuit, so don't need to put loads of air into suit, so maybe this helps limit the opportunity for water ingress.
I also notice I hardly seem to get much water into my BCD yet others doing the same profile etc have loads to drain out after the dive.

How does that work?

With BCs water gets in when using the wrong dump (ie not the highest so no air to dump) but varies a LOT with design. Some BCs definitely get a LOT more water in than others through normal use.

Check that you have positioned the cuff dump correctly (not that hard to do) and if so stick your mouth over the dump from the outside of your suit and blow, if your breath goes through you have either a leak, or its not seated correctly.
When I was in Skye the other year, my cuff dump leaked, or so I thought. I replaced it whilst I was there with a new spare I had and it still leaked. I checked the rubber outer flange around the dump and plastered silicone and glue all over it and it still leaked.
I sent the suit to Divers Warehouse for a new flange and dump to be fitted and the found it was the suit seam that was leaking, just near to the dump. So, its woth getting the suit pressure tested.

Good luck

unscrew the plastic cover over the valve and take out the rubber diaphram and make sure its clean replace and check again if it gets water through it as it can usualy clog up with talc and crap

I know the design is part of it, I have a Buddy Commando Profile TD, which has no bladder on the forward part of the shoulders, and get very little water in. My partner has a more recent model, which has air bladders that go right over the forward part of the shoulder. I used this for a week last year and found it would get a lot more water in than my regular one, so this seems to be part of it.

However, when others have used my BC they somehow manage to get lots of water in, so that must be down to them using the wrong dump or not positioning it correctly.
