I cleaned away all the lime from all water outlets. Installed the HydroFlow, and waited. The next day I washed my hair and it was not fuzzy like before. Washed my linens and they were not stiff! My life is good again! I recommend this 100% - forget the salt bags! Thank you!

Too early to tell

I have very hard water, and a system that has never seen soft water. I might not see complete descaling for a while if ever.
However, build up of minerals in our kettle seeds to be less and slower, chrome bath taps seem cleaner.
Stay tuned!

I researched this product in order to replace my water softener system. So tired of hauling bags of salt into the house after so many years. After
40 days I have noticed a big difference in the water hardness in the house. Nothing short of amazing. I wish I had this piece of tech installed in my home years ago. Thanks HydroFLOW!!

I don't usually write reviews but Hydroflow deserves one.

The first one arrived with a problem. Because of a move and travel, we were not able to install for more than 30 days after receipt. An email to Mike and a replacement was on its way. Installed and working with no problems.

I used Hydroflow in a previous house; absolutely love it. And love not carrying heavy bags of salt.

The HydroFLOW® Pearl is the solution for hard limescale deposits in the home. It is designed to protect your residential hot water heating system as well as appliances such as dishwashers and washing machines. In the majority of cases to eliminate limescale-stains from taps, sinks and bathtubs or make them much easier to clean.

Limescale build-up in domestic heating systems can cause blockages, necessitating replacement of equipment, decreasing heating efficiency and thereby increasing costs. Just 0.8 mm of limescale can decrease heating efficiency by as much as 10%*.

Unlike other water softeners on the market, the HydroFLOW® Pearl does not chemically alter the water or remove minerals. Instead, it applies an electric field so that scale forms in suspension in the water, rather than as a hard encrustation on heating elements and pipe surfaces.

The HydroFLOW® Pearl fits easily around existing pipework on the cold feed to where the water is heated, for example on the inlet to a hot water cylinder or the inlet to a combination boiler.

  • REDUCE COSTS: Reduces energy consumption with an average one year payback period.

  • EASY INSTALLATION: Non-intrusive and easy to install! No plumbing modifications required. Maintenance-free. Works on any pipe, even PEX and PVC - just attach to cold water line into Hot Water tank or Boiler. Fits pipes up to 25mm (1”) outer diameter.

  • ECO-FRIENDLY: Our water softener products do not introduce chemicals into your drinking water and the environment.

Installation of this device does not replace periodic equipment preventative maintenance procedures, such as purging of your water heater.
