Rattling flasks: The rattle you hear is a small metal disc that sits between the double wall of your flask and aids in the vacuum insulation process. Sometimes the disc becomes dislodged, creating a small noise or rattle. This will not affect the insulation or structural integrity of your flask.

Yes, it's normal for a water bottle to make noise due to gas bubbles clinging onto the imperfections in the glass or plastic.
Yes, it is safe to drink from a Hydro Flask.
The water whistle works because the air inside the straw is vibrating. The submerged part of the straw is filled with both water and air. When you blow across the top of the longer straw segment you cause the column of air to vibrate. As this vibrates it creates the whistling sound.
The whistling sound is the result of too much water pressure inside your lines. This can be the results of a few different culprits. One of the most common is the inside of your piping has a buildup of debris. Over time, excess mineral buildup in the water can attach to the inside of your pipes.
Gently push the air valve with your finger, or a pen, from the top, without pushing the air valve off the cap. The air valve is the small round opening above the cap. You won't need to do this every time you drink. The fix should last, and it should loosen the tightness of the air valve.
The hydroflask is quite versatile and does a good job at insulating cold beverages for up to 24 hours, hot beverages up to 12 hours.
Our tests favored Hydro Flask (it's one of our winners, in fact). It has excellent cold retention and a convenient straw lid and it can fit in your car's cup holder easily. However, Yeti water bottles are also good—if you prefer that chug-style cap. And you'd be equally happy with its cold retention and durability.
Although they're a great way to stay hydrated on the go, they can also be a breeding ground for bacteria and mold if you don't give them a good scrub every now and again. “Everything that touches our reusable water bottles can transmit bacteria.
Some of us Inhale more air through mouth than nose. So, while we drink something we swallow some amount air that tends to make sounds.
“Gram negative rods – another common bacterium found in unwashed bottles – can lead to urogenital tract infections and pneumonia.” Grant warns: “If there's a build-up of mould inside the bottle, this can cause allergy symptoms, such as a runny nose, sneezing, or red and itchy eyes.
The “pop” you hear is caused by a sudden change in air pressure. When you release the cap, the higher-pressure air inside the bottle rushes out into the lower-pressure air inside the room. This sudden expansion creates a pressure wave that you hear as sound.
Though the insulation of a quality vacuum bottle should remain intact, there are other factors that can affect its performance over time. For instance, any damage to the outer shell may cause air leaks which would then impact the insulation efficiency of the bottle itself.
Air Leakage or Dripping Sounds:
If there is water in the bottle and the lid is not sealed correctly, air or liquid movement may produce these noises.
This is because mold releases chemicals called mycotoxins as it grows, which can leave a persistent smell in your hydro flask.
Each Hydro Flask is constructed from premium-grade stainless steel, renowned for its durability and resistance to corrosion. This material is more expensive than the plastic used in many other water bottles.
All YETI drinkware is crafted from 18/8 kitchen grade stainless steel and are BPA free, meaning they are not only absolutely safe to drink from, but are also puncture and rust resistant.
You do not need to refrigerate your Hydro Flask....
Most of us keep liquids in them all day, every day. Because of this, they rarely dry completely. And without proper cleaning, your water bottle can become an ecosystem of mold and bacteria.
Dairy products: Milk, cream, and other dairy products can spoil quickly and leave behind an unpleasant odor or taste. It is not recommended to put these types of liquids in Hydro Flasks.

The noise you're hearing is air escaping through the valve, this allows air back into the bottle so water can flow out. To help alleviate this noise, pull the air valve up and allow it to fall back into position.
A: Wiggle/loosen the little rubber stopper under the lid. Mine used to make a loud dolphin sound and stopped once I did that.
