Yes. That's exactly what the filter is for.@lowwall Ok, so if it were aluminum oxide, I would see it in the filter? I don't have the reg currently (already dropped it off for service) but I made a point to regularly inspect my filter and never saw anything like that. Guess we'll wait and see what the tech says about it.
Yes, not much to add to the posts above. A white substance on the tank walls does not sound normal. And good point about the filter doing it's job, but something seems to get through and abrades our pistons in the first stage in time.@Geo7 Wait, so your concern is that there may be aluminum oxide contamination coming from inside the tank....One of my tanks has a white, powdery buildup on the inside. The fellow that did the viz (not the guy that sold me my reg, different dive shop) said it was fine, that he'd hit it with a brush and it hadn't come off, so it wouldn't be an issue, but well, could that be the root cause?
Just for giggles and grins. . . are one of those people who after removing the first stage from your tank, you open the tank valve and blow compressed air on the inlet of the regulator?Hey all,
Just recently my Tusa RS 1001 regset, which I purchased back in March and has around 20 dives on it, developed a slow leak on the second stages. I took it in to the shop that sold it to me, and the owner put it on his IP gauge. Sure enough, slow internal pressure creep resulting from HP seat failure. He asked me if I'd been using it on steel tanks, which I have not, I've only used it on aluminum tanks; however, my local fill guy is known for his "hot fills" some of which are in the 3400-3500 psi territory. I specifically asked him to not overfill mine past 3300, since my reg is yoke and can't handle above 232 bar, and as far as I can tell, the pressure has never been above 3400 psi. The owner of the dive shop says it would take more like 3600-3800, and more dives than I've put on the regset, to do the sort of damage that's happened here, and he has said he believes it is a defective part and that he'll see to it that it gets fixed, but I'm concerned something I've done/allowed may have caused this, since it seems like an extremely rapid failing of a new regset. Would fills 3400 (or, assuming perhaps my gauge is slightly off or some other error is in affect, 3500) psi cause this sort of thing? If not, can you think of anything else that would?
Thanks
