Hydro Floss Reservoir Plastic Insert

This is the plastic insert for the Hydro Floss Reservoir. This is NOT the reservoir itself.

This plastic piece is easily replaceable by inserting the new one into the reservoir tank.

You should have the rubber O-Ring as well. If that part is missing or not intact consider getting one of those as well.

This plastic insert will fit all genuine Hydro Floss oral irrigators.


This video shows how the reservoir, the lid, the plastic insert and the black o-ring all fit together.
