We start by removing the valve or regulator on the tank and setting off to the side. We perform a series of visual inspections inside and outside of the tank. we then put the tank into the hydro-test machine and measure the elastic expansion of the tank. We compare the elastic expansion to the specifications provided by the manufacturer. If the tank has enough elasticity it passes. If the tank loses elasticity, instead of expanding when filled it can burst. Tanks are then dried and labeled with the new date. Lastly the valve or regulator is torqued back on with the appropriate torque and threadlocker as specified by the manufacturer.
You can order a prepaid kit from our online store here. It includes the cost of the test, shipping, a sturdy box, and the packing materials needed to get us the tank safely. Make sure your tank is completely empty before shipping.
We start testing in batches of four every Thursday and Friday. Tanks then need to dried and labeled. All tanks ship out on Mondays. If you are shipping in your tank the distance to our facility is the biggest factor in your turn around time. Most tanks arrive on Wednesday and ship out on Monday. If you are across the country and want a faster shipping method we can do that for a little extra.
