Cleaning and Maintenance Tips for Hydrapak’s Reversible Reservoirs

One of the key benefits of Hydrapak’s Reversible Reservoir is the ability to easily clean and dry it after each use; extending the product lifetime.  Since microorganisms grow in water, the most critical element to cleaning a hydration reservoir is drying.  This is where Hydrapak’s unique reversible design proves its superiority.

Steps to Clean and Dry

  1. Remove the top slider and empty remaining liquid.
  2. Reach hand inside reservoir, grab the bottom, and then pull to reverse; turning the reservoir inside out.
  3. Wash using hot tap water and mild soap, removing any residue.
  4. Rinse thoroughly.
  5. Let stand in reversed state to dry completely.
  6.  To store, return to original state or keep in the reversed position depending on your preference.

Drink Tube Cleaning

For Plug-N-Play Users

The first step for users with the Plug-N-Play connector should disconnect drink tube, then rinse the inside tube with hot tap water from the connector end while holding the opposite end lower and pinching the valve to flush the system.

For Fixed Connector Users

Users with systems having a fixed connector should flush their tube with warm water prior to reversing the reservoir to clean.  After an initial rinse of the reservoir, partially fill it with hot tap water then raise reservoir above pinched bite valve until the entire contents are flushed.  Next, follow steps 2 – 6 above.  See how to Upgrade to Plug-N-Play: Video

Tube Brush

A Hydrapak Tube Brush is available to scrub any residue caught inside the drink tube.  To use, remove the tube from the reservoir, insert the brush, and then draw back and forth until residue is gone.  Note; Brush can only be used with straight connectors and not older angled models.

Other Cleaning  and Maintenance Tips


The material used in Hydrapak reservoirs, Polyurethane, is chosen for strength and flexibility.  It is porous and can be stained like fabric.  Reservoir staining is generally caused by food coloring used in liquids.  This staining does not affect the functionality of the reservoir, yet can be difficult to remove.  A company called Clean Ethics has engineered a chlorine free, non-toxic, and biodegradable tablet that is safe for virtually any surface, called Bottle Bright.  This product is designed to combat stains and odors and is perfect for hydration bladders

Plastic Taste

The material used in Hydrapak reservoirs, Polyurethane, is chosen for superior strength and flexibility over reservoirs made from Polyethylene.  Some users can initially notice a plastic taste which can be reduced by simply squeezing juice from a lemon into the reservoir, filling it with water,  then place in the freezer.   After frozen, remove, thaw, and rinse.


Plug-N-Play users may need to occasionally lubricate the rubber O-ring on their connector to ensure a smooth connection and for leak prevention.  If necessary, apply glycerin, silicone, or pure bees wax as lubricants. Avoid olive oil, coconut oil, cooking oils, etc. These types of oils cause the seal to swell and make it difficult for the system to be disengaged causing the user to increase the force necessary to remove the hose.
