Water intrusion with Atomics when doing valve drills?

[sunny_diver]

Atomics owners ... do you worry about water intrusion into your hoses or first stages when doing valve drills? The seat saver feature on their second stages means the second stage is open when not pressurized. Since valve drills involve depressurizing hoses, it got me wondering.

No worries. When breathing down the reg after shutdown, I feel a difference well before pressure is low enough for the seat saver to engage. Additionally, the valve is immediately turned on and 2nd stage purged, so even if water were to somehow make it into the hose, it won't travel against gravity up the hose. And even if it somehow did (e.g., out of trim), it would be purged well before reaching the first stage where it might linger and cause corrosion.

Been doing valve drills with my M1’s for years … never had an issue
