The HydroFLOW product range
A small, smart device that clips externally onto the home’s water pipe — no pipe cutting, no plumber, no system changes. An eco-friendly solution for managing limescale in homes.
The HydroFLOW Pearl helps reduce limescale using unique, globally patented electronic technology. Unlike traditional softeners, it treats the entire plumbing system with no salt or chemicals. This helps keep boilers, pipework and appliances running efficiently. With simple plug-in operation and low maintenance, the HydroFLOW Pearl is an eco-friendly way to manage limescale in smaller homes — suitable for all pipe types up to 24mm, including washing machines and water heaters.

While HydroFLOW doesn’t remove minerals from the water, it helps control limescale. The Pearl unit clips onto the pipe and applies its unique signal, encouraging limescale to form as tiny particles in the water instead of hard deposits on surfaces. Over time, this can help reduce existing limescale and make it easier to clean new build-up.
The HydroFLOW Pearl is fitted externally onto any type of water pipe up to 24mm, continuously inducing a unique signal that affects the natural salts present in the water.
Clips externally onto the pipe and plugs into a standard power socket — no plumber required.

Plug-in connectionPearl is an excellent solution for focused treatment at a specific point — for example, the cold-water line feeding the water heater, where limescale and Israel’s hard hot water do the most damage. But if you want protection for your entire home water system, we recommend combining it with Pearl Plus at the main inlet — giving you both targeted treatment at the most sensitive point and broad coverage for the whole home.
A strong signal that propagates over long distances — general protection for the entire home water system.
Targeted protection at exactly the point where limescale and hot-water hardness do the most damage.
Pearl is the simplest home solution — no plumber, no chemicals.
