Pump & Piston (Replacement)

Over the years I have had 2 hydro Floss machines. They are workhorses and work great. My latest machine quit working and I ordered replacement parts and by following the instructions online I was able to easily fix my machine for a very reasonable cost. I highly recommend Hydro Floss as the greatest water flosser machine and it now comes with a fabulous replacement parts option. Hydro Floss is simply the best.

The pump arrived OK, and it works well. I took the liberty of using some dielectric grease on the big end of the connecting rod. It took out the rattle caused by the friction between the dry components.

Was easy to install

Relaxed it but still doesn’t feel like it did when I first changed piston 3 years ago

This is the first time I required any replacement parts for my Hydrofloss. I purchased my Hydrofloss in the early 1980's directly from Hydrofloss. I have used it daily until the pump finally failed a couple of weeks ago. The new pump was very easy to install and works perfectly. Thanks for maintaining parts availability and video installation instructions for this outstanding product!
