Look for limescale marks on surfaces like glassware, cutlery, taps, showerheads, bathtubs, toilets, and other areas in bathrooms and kitchens. Limescale appears as white marks that can darken over time, making them hard to remove with regular cleaning products. You may also notice lower water pressure in pipes and the need to replace tap washers frequently. Additionally, hard water can lead to higher electricity bills and premature aging of appliances due to limescale buildup in water boilers and other systems.
-
Signs of hard water are often noticeable across multiple surfaces and household items. Look for:
White scaling on taps and other fixtures
Lime marks on cutlery, glassware and dishes
Soap residue on sinks and bathtubs
White stains on laundry
Reduced lathering of soap or shampoo
Dry, itchy skin and dull hair after showering
-
Aqua’s electric limescale dissolver is installed on the main incoming water pipe, where it creates a powerful electromagnetic field. field. As water passes through this field, existing iron particles are accelerated, breaking down calcium (lime) into fine particles, preventing deposits. Instead, calcium stays suspended and is flushed out of your system, keeping surfaces free of buildup. This technology works continuously, with 100% effectiveness as long as Aqua is connected to electricity.
-
Aqua products can be mounted on most types of pipes, including copper, PVC/polyethylene, galvanized and stainless steel.
