I just don't log dives
I have abrand new set of regs and octo.
Hooked them up right out of the box.
Both freeflow badly in pre-dive and dive positions.
How do I adjust them to make it stop?
 
Unless you are familure with reg service, my suggestion is you don't. It's fairly common for new regs to need a tuneup before going diving the first time. It's not a difficult thing to do but considering it's a new reg, it should go back to the shop where you purchased it because they should have done a check and setup on it before it left the store. If you purchased online....well it needs to go back to them. Your LDS may be kind enought to do it for you but it's likely they will charge you a setup fee. If it came from an LDS and was not set up.....find a new LDS.
 
1+ what Herman said (as usual).

If these came from a LDS, I'd be "hopping mad" because it means the LDS did not check them out before letting them go out the door. Totally unacceptable.

If they were "new in the box" from ebay.... well, they may have been "new" in that box on a back room shelf for several years and a touchup tuning is required.

Sorry this happened to you with new regs. The fix should be pretty simple however.

Good luck and best wishes.
 
In most regs, the second stage seat is in contact with the orifice under spring pressure. The pressure is greater in unbalanced second stages than in balanced second stages (and there are some designs that remove the pressure on the seat when the reg is unpressurized, but they cause more problems than they solve).

The result is that between being adjusted at the factory and making the first dive with a customer a seating groove will develop. If the tech at the factory did not properly anticipate this effect and detune the reg slightly to compensate, it will need adjustment.

Ideally a shop will re-tune it before they sell it, or at least have a tech tune the regs after thay have been in stock a few weeks (after most of the seating groove effect has occurred) but I don't know of many shops that actually do that.
 
If both second stages are freeflowing badly, like a real gush and not just a slight hiss, I'd suspect a problem with the first stage. When you bring to someone to check, make sure they check the IP.
