What To Do About Low Pressure in Your Water Flosser

Clean Your Water Flosser Jet Tips

Remove the water flosser tip from the unit using the eject button.
Soak the tip in a container of hydrogen peroxide or white vinegar for 5-7 minutes.
Rinse the tip under warm water.

Note: For maximum effectiveness, replace water flosser tips every 3-6 months as the tips can become clogged and/or affected by mineral deposits.

Clean Your Water Flosser

We recommend cleaning your water flosser every 1 to 3 months to ensure optimal performance.

For Countertop Models:

Mix 2-4 tablespoons (1-2 ounces) of white vinegar with 16 ounces of warm water.
Fill the reservoir with the solution, and then run 1/2 of it through the water flosser.
With the unit OFF, place the water flosser handle in the sink and allow the solution to gradually drain out of the handle.
Run any remaining solution through the unit and then rinse with a full reservoir of warm water.

For Cordless Models:

Add 1 tablespoon of white vinegar to a full reservoir of warm water.
Point the handle and tip into the sink.
Turn unit ON and run until reservoir is empty.
Rinse by repeating with a full reservoir of clean warm water.

Charge the Unit (Rechargeable Handheld Cordless Models) or Replace the Batteries (AA Battery Models)

Most WATERPIK Handheld Cordless models are equipped with either a rechargeable lithium-ion or rechargeable NiMh battery. Refer to your product manual for detailed charging instructions.

Ensure the power switch is in the OFF position when charging.
Do not run the battery down completely. This may shorten the battery lifespan.

To replace the batteries in the Cordless Express, Cordless Revive, or Cordless Freedom water flosser:

Replace batteries when there is a noticeable change in performance.
The type and quality of AA battery used impacts performance of the product.
Use 3 AA Batteries (replace with alkaline or NiMH batteries only)
Replace all batteries at the same time with new batteries of the same type and brand.
