Know your tank’s recertification requirements
Tank Inspection
#1 – Visually inspect the tank for cracks. You have to remove the tank cover to see the whole tank.
IS THE TANK CERTIFIED TO USE?
#2 – Check for DOT or ISO/UN numbers
HYDROSTATIC TEST DATE
#3 Look for the born on date or the date of the last Hydrotest
TANK DATES and LIFESPAN
– All tanks must be Hydrotested every 5 years
– All tanks have a 15 year lifespan
If you have a tank with an ISO number and you live and play paintball in the US, you need to make sure your tank also has the UN symbol and the USA certification code stamped on your tank in conjunction with the ISO number.
If your tank ONLY has an ISO number, it is NOT VALID for use in the United States.
