Rehydrating your Echo Flask™

If your Echo Flask™ arrived dry or nearly empty—that is completely okay! 

Similarly, if you haven’t used your Flask for a while and the internal membrane has dried out, it simply means the electrode membrane may need a little rehydration before regular use.

Getting Your Echo Flask™ Ready for Use

If you notice few or no bubbles at first, don’t worry—this is completely normal and part of the break-in process.

How to Rehydrate Your Echo Flask™

1. Fill your flask with hot, non-chlorinated water

   • Hot to the touch is perfect

   • Do not use boiling water

2. Run a cleaning cycle:

   • Swipe up on the  display screen

   • Tap the gear icon ⚙️

   • Select “Clean Flask” and press Play. This will start a 10-minute cleaning cycle.

3. Once the cleaning cycle is complete:

   • Pour out the water

   • Refill the flask with fresh, warm, non-chlorinated water (same as before)

4. Let the flask sit for at least 48 hours to allow the internal membranes to fully hydrate. You may run cycles and use them during this time.  Please refer to the 🔗Understanding your Flask™ Generator  for use.

What You Might Notice (Totally Normal!)

• Large or sporadic bubbles at first

• Over time, bubbles become finer and more consistent

• Bubble activity may gradually increase as hydration improves

Important Notes:

• It may take up to a week of regular and consistent use to fully rehydrate the electrode and achieve a consistent bubble flow.
• If you see progress, this means your Flask is working properly
• If your flask has had no progress and does not produce any bubbles after a week, please contact our customer service team at support@echowater.com for assistance.
