Scubapro S620TI allowing water in

[Jga37]

Sucking in water. Had it looked at 3 times LDS they replaced normal service parts, flapper, rings. Still sucks water sometimes. It’s now an intermittent problem. Driving me and shop crazy. Please help. And no I’m not sucking too hard

Tell us a bit more.
When in the breathing cycle do you breathe wet?
After you purge, is the very next breath wet too?
Are you inverted?
Have you had it tuned "light"?
Is it just intermittent and unexpected?

Did you change the mouth piece?

Yes I changed mouthpiece but had the problem prior to that

The water comes in on the intake cycle can feel slight gurgling and it happens both deep 60-130 diving and pool. I am not inverted. Originally we found slight debris under edge of translucent disk.

replace the exhalation diaphragm *translucent disc*, and clean the seals in the reg body. Remove, inspect, and clean the inhalation diaphragm

You've now heard about three of the six possible sources of a leak on inhalation:
In order of likelihood:
- hole/tear in mouthpiece

- flaw or debris in exhalation valve

- wrinkle, hole or dislodged main diaphragm

The last three possibilities are
- sheared, dislodged or wrong-sized oring(s) sealing the barrel or adjuster to the case

- a crack or flaw in the case itself

- a sealing issue where the Venturi vane penetrates the case.

You didn't mention whether they changed the exhalation valve after finding debris. The debris may have been a red herring, with the more likely problem being a flaw in the skirt of the valve leaflet.

I recently had gurgling problems and it was because i tried using those stupid silicone mouthpieces that don't always exactly fit the body of the reg. pissed me off because they were all color matchy, too.

oh well. back to comfobite.

A quick test for water tight integrity is to suck on the reg with the first stage on a tank that's turned off. If it holds vacuum its generally good to go. Not a fool proof test tho.

You could try doing that and moving the reg and manipulating controls on your 2nd stage to try and find the source of the leak.

Especially since on the S620ti the adjuster seals only on the outer case, and with one o-ring. A great feature imho, but that o-ring needs to be in order.
