First stage problem?

[Jai Bar]

Hi,

Not sure if this is a problem- or where it originates a from:

When my mk25 first stage is closed with a dust cap, and I try to take a breath from it- instead of being sealed I can hear air flowing into the inflator hose..

Is it a known, trivial failure? I guess both the inflator hose and second stage are connected to the same intermediate pressure chamber, so some sealing is wrong there?

Any thoughts? Oh, the regulator is immediately after service, but the next time I'll be by the shop to complain is in a couple of weeks, and I'd like to educate myself when explaining the problem.

Thanks

Put your finger over the opening rather than the dust cap, if you still hear of feel air coming through pull the hose and plug that hole. See what happens, if no leak it’s probably the shreader valve in the hose.
