Why Does My Hydro Flask Stop Working?

Now you have understood that a hydro flask water bottle relies on the vacuum insulation tech to keep water cold for a long period and you must have known whether it is broken. So the main reason why hydro flask stops working is: 

01. A visible dent on the hydro flask that would cause the two walls of stainless steel collides together, which makes vacuum insulation disappear and stop working to keep ice cold for a long period of time; 

02. Some hydro flask water bottles without visible dent but is still not working? Why is that? For these hydro flask bottles stop working without visible dent on it, you might purchase a poor vacuum insulation hydro flask water bottle which was manufactured in fault by the seller. The fault may result from a poor welding getter that should have kept vacuum insulation sustainable for years. In this situation, you can hear a suspect rattling noise inside the flask yet its vacuum insulation is still working at the beginning. However, this problem will get worse as time goes by and eventually result in the stop of working. That’s why most manufacturers can’t identify the defect and select it out during production. This flaw is rare to see but still happens.

Both of the problems (dents on bottle and poor insulation vacuum performance) can’t be fixed. And you have to return it back to the seller for repair.

How do you tell if your hydro flask is broken? You can test the insulation of your flask at home with boiling water. First, you should pour the boiling water from a kettle or pot directly into the hydro flask, filling it all the way to the neck. You must be cautious enough to prevent yourself from scalding during the first step. And do not grasp the flask while filling with boiling water. Also, do not place the cap over the flask. After about 5 minutes, you should feel the surface of the flask (below the neck). If you feel any hot spots, then the insulation has been compromised.
