I keep getting a "this site can't be reached" even when I get there from a different starting point. I get to the list of states but CA doesn't seem to be working.
How do you define "low pressure?" I have a CO2 extinguisher that is rated for 1800 psi and I'm sure they can test those. I don't know how much pressure paintball tanks go to but I was thinking it was over 3500 psi. They test those too. I didn't get the impression that they were in any way shady. The hydro guy said he pressured my tanks to 3750, measured how much expansion there was, and how much contraction there was when depressurized, and everything was within the acceptable limits. Aside from passing the visual, what more is there? Knowing that it passed those tests I feel confident to fill my tanks to 2475 psi. I imagine that dive shops in the area probably send them to the same place I went to as I went to since I could only find one other place that does hydro testing within about 25-30 miles.
I'll try again later to get the link to work--it's Sunday evening and maybe it's down for maintenance.
I didn't read the scam link yet--I'll do that now.
