We have released a new repair video on our YouTube channel, this time for the Waterpik WP-450 water flosser. This is a straightforward repair to fix a very popular Waterpik model.

The video was taken from our photographic Waterpik WP-450 repair guide, which goes into slightly more detail than the video.
I purchased two Waterpik products…MODEL: WP-450. Both were made in China and have stopped working shortly after one year of careful useage. The units have a very short life span. So disappointed!!
