I am going to assume it was neglected, period. I know it needs purged, and I want it inspected before it goes back into service, and would like to re-paint it. Will this be cost efective, or would I be bettr off throwing $90.00 at new one?

It doesn't need the valve changed out, and I can handle the re-paint, but how much is an inspection and purge?
The tank is dated 2006, so maybe I can just inspect for intrnal rust while I have the valve off while refurbishing tank.

The $90 is for a new tank, purging, first fill, and a 'complimentary' soap test, $75 just for the tanks, which isn't that much more than Dale's prices after shipping. How much pressure can a tank take? I'd like to pressure test the valve myself before I get it filled. I can put 150lbs of air pressure on it at home.

I believe the relief valve is set at 350. If that's the case, it probably has a 5 to 1 safety factor. Burst would be above 1750. However, I may be totally wrong on this.

I had a propane tech at local place where they test and refit tanks tell me 260psi..
Oh well...

Larry, when you hydro test a hose, how much pressure do you put on it?
