Changing Apeks 1st stages UST4 to DST4 ?

colinicky · 6th April 2008, 21:22

I currently have 2 UST4 1st stages but today 1 of them decided to start leaking somewhere in the swivel bit

.
Now I am meant to be diving on Wednesday & Thursday & I have a spare DST4 laying infront of me .

Is there any reason why I shouldn't just put the DST4 on untill I get the UST4 serviced ?
If it makes any difference the dives are max 30 metres
TIA

don't use it on the O2 side the interstage pressure isn't constant over depth.

On the dil side should be fine though, the real trick is get the service kit and service it

Well as I don't have a clue it will go away to be serviced & from what you say I'm ok as it is the dil side that leaks .
many thanks
