Is my undersuit the problem???

[String]

Just bought a tubigrip to try. Duct tape didn't work so will see if this bandage works wonders.
As for extra weight its mainly the fact i cant cram any more bean bags into my already full belt more than any other reason. I do need to rethink my weight system (currently alu backplate).
Im just not a fan of having more gas in my suit than i need - find it very uncomfortable.

Anyway 2 dives in capenwray tomorrow to experiment a bit.

Agir Backplate, 5/6lb in weight, also try putting weight on your cam belt of your bdc, 1lb each side can work a treat.

Just tried 2 dives today with tubigrip and 1kg extra weight.
Valve was "ok" to dump. Left it full open and when i rolled it dumped - still nowhere near as fast as a cuff dump but it did work and felt a bit more in control. Felt horribly overweighted though so next try will be just the bandage to see if that cures it.
My cursed feet-down trim has returned as well with this new suit - im thinking SS backplate and/or cam-strap blocks will help this somewhat.

After today i no longer desperately NEED my cuff dump but do still feel cuff dump is more efficient

so you're moving in the right direction then..

if you felt you were overweighted - then I would address that first. Being over weighted of course means that you add more gas to compensate. then as you ascend you need to vent that gas.. and we suddenly have a possible root cause for the valve not dumping enough - too much suit gas and not enough time to dump it..

if you are correctly weighted (are you diving twins or a single by the way?) then the amount of gas you would need for the suit is minimal (just enough to loft the material in your weezle) - again I assume you are using a wing and you are using it for buoyancy (rather than the suit). It will also improve your gas consumption as you dont have the 'see-sawing' effect of adding loads of gas - only to dump some of it, then add some etc..

You feel that you trim is off - could I suggest going diving with someone who dives the setup you currently dive? forgive me if I have this wrong - but it sounds like you're whole setup is pretty recent and not just the suit? again apologies if I have this wrong..

As Scuba-g suggests - getting a SS backplate might help shift weight into a better place and take it off any weight belts you might use..

I find that old cut up sock stops the undersuit from blocking my dump valve.

Basically i deliberately overweighted (as suggested above by nigel) to see if the dump valve was more effective - normally i carry less. Certainly felt like a lot more inflating/dumping than normal and more general faff.

Yesterday single and yes a wing. The only "new" kit is the suit with shoulder dump vs my older suits with a cuff dump hence the issue with this thread wondering if its my undersuit. The wing etc ive had for about a year.

Basically, im struggling to adapt to a shoulder dump from a cuff dump as im finding it isn't dumping as quickly or reliably. I must admit now after some testing im beginning to believe its my undersuit causing some issues and just being unfamiliar with the shoulder setup. Im looking for a new undersuit anyway as im cold in my weezle.

I went from the weezle extreme (which I loved as its got that snug warm duvet feeling on a cold winters day) to Artics with a base layer. I am just as warm (diving at the moment in 5C water for upto 45 minutes) and instantly got rid of the chance of material getting stuck in the dump valve (as the undersuit doesn't rely on lofting of the material like the weezle does).

if you can borrow someones artics and have a play. if you don't like, try something else.. there are a *lot* of people who like the artics.. very good in a suit flood too - as I found out at the YD stoney gig a couple of weeks ago..

Maybe i dont dive with enough air in the suit but generally i get cold in the weezle in anything 12c or lower. After 30 mins i start to notice it. 6c yesterday and 50 mins was really feeling it (with wicking baselayer and thin fleece top under it).

Extreme not extreme plus. Im considering a Santi 400.
