We just left Vallarta UnderSea and Armando calibrated both of our regulators. The one originally on the yellow hose had a small leak. He corrected it and test the other. Both are now working perfect. Armando also gave us some O rings for the dive tank valve. We connected the stage one and the yellow hose with the other gear and tested the whole thing and found none.
The tank should be stamped with the pressure rating. In our case I think it may be 2400 because last time we got it filled the tank gauge read 2000 but it could have been somewhat higher as I did not look that good. I’ll check that out again. We had just got it hydro’static inspected and filled. Our tank is an old one and a smaller one. Does not hold the volume of air as the newer tanks do. I can get just abot a bottom cleaning out of one tank if the prop and bottom are not bad.
We went to Vallarta UnderSea and Armando put our dive tank regulator back together for us. Now we will sell the tank and regulator setup. As we suspected it is worth a lot more here than in the US. Easily enough to off'set the Depot air generator and extras we purchsed.
