You are correct. This is a beer-keg 5 pound CO2 tank that I get refilled at
Carbonics but every five years it needs a hydro test.

I can let Carbonics send it out, but I figured I'd ask what others do in
case you have a good source for hydrology testing.

I guess the sources a
- Welding outfits (such as Praxair and Airgas)
- Soda outfits (such as Carbonics)
- Fire Extinguisher outfits
- Scuba outfits

I can let Carbonics do it but I was wondering if you had a good source
already, from experience.

Thanks
