After installing a P-valve to your dry suit, there is always some “knob” and hose that catches on stuff like your dry suit underwear while donning.
Especially the older styles balanced style P-valve with the balancing check valve outside of the actual valve.
What I always do to create a smooth surface again on the inside of my dry suits is to add a protective cover of neoprene over the P-valve.
That way there is no problem anymore with entering the suit.
Not that it is a “problem” without the cover… It’s just more comfortable and smooth.
You start with cutting a piece of thin (2mm) neoprene the size of the cover.
I always lay it on the inside of the suit on top of the valve and mark the neoprene so it covers the entire valve assembly.
Leave some extra room on the top and bottom to secure it to the suit. (5cm)
Glue the top of the cover to the suit so it covers the whole P-valve assembly like you initially cut the sheet of neoprene.
Next you cut a hole on the top to feed the hose through.
Make sure there is no stress on the hose at the hole.
Now you can mark where the bottom of the cover meets the suit.
Here you can glue a piece of Velcro as well at the lower end of the cover.
This way you can still easily access the P-valve assembly to perform maintenance.
And now your basically done.
The only downside I found with this cover is that in case of a dry suit flood, the cover dries slower than the rest of my (trilaminate) suit.
Everybody who ever tried those pesky dry gloves with a latex seal knows what a struggle it can be to put them on.
However, there is a little trick that makes this quite easy.
You should not try to fight your hand into the narrow seal opening, but instead you can point the seal into the glove so it’s facing the same direction as your dry suit’s wrist seals when you put your suit on.
Now it’s very easy to just point your hand and slide it into the glove…
A little talcum powder on the seal helps this a lot, but it’s very nice to have your seals in good condition so they don’t “stick”. I don’t use talcum powder or anything at all.
Your hand should ideally just slide through.
Once your hand is in the glove, you should pull the side of the seal/glove to pull the glove seal’s edge up onto the dry suit wrist seal.
Make sure you check the entire circumference of your wrist to see if the glove seal is over the dry suit wrist seal, there should be no skin, liner or under glove showing or it will leak.
This part can be tricky at first, but just needs some practise.
Don’t worry that the seal is facing the “wrong” way; if you did it right it won’t leak a drop.
