Wanting to buy / scrounge drysuit dump valves (2 kinds)


Well-known member
Does anyone have a S/H auto shoulder dump valve they would sell to me? (It's for a sacrificial drysuit which will get wrecked on a gnarly caving project, so no point shelling out on a brand spanking new dump valve.) Push button preferred rather than pull cord; then again, beggars can't be choosers.

Separately, I'm looking for second hand Apeks cuff dump valves. CDG Newsletter 221 (October 2021, page 4) has a note about improvements to the CDG DIY P valve system. I want to make some more of these.

There are a few versions of the Apeks cuff dump but the type I'm after is the one with a back plate which has thick spokes connecting the outer rim to a central point. I've attached a picture which shows one modified into a P-valve.

Many divers dislike cuff dumps, so often swap them for a proper shoulder dump valve. The old cuff dump usually gets chucked in a box somewhere. If anyone can dig deep and help with either request above, please could you send a P.M?

I can probably help you with this but I won't be home until Sunday night as I will be travelling to the Dales straight from work this afternoon. Hope to catch up with you at Greenclose over the weekend.

Ben - thanks! How much do I owe you?

Martin - thanks! Yep, hoping to catch up with you all at some stage this weekend.

Aye - but you've done me a shed load of favours too!

But thanks. I have to go to the compressor over the next day or two, to do a job at the request of Kev G, so if you could drop me a quick email once you've been, I can kill 2 birds with one stone.
