The WS 455 Water Softener is a sleek, fully automatic addition to Presco’s expanding salt and water treatment range. Designed specifically for UK homes and plumbing systems, this compact unit delivers consistently soft, luxury water while remaining efficient, reliable, and easy to live with.
 
Compatible with all Water Softening Tablets and Blocks, see our range of Blocks or Tablets
Engineered with modern electronics, the WS 455 intelligently regenerates only when required, helping to reduce salt, water, and energy consumption without compromising performance. Its durable rotary valve design features fewer moving parts than traditional systems, enhancing reliability and long-term operation.
 
By removing the minerals responsible for limescale and soap scum, the WS 455 protects household appliances, plumbing, and surfaces, while leaving water that feels kinder to skin and hair. Soaps, shampoos, and detergents lather more easily and rinse away cleanly using less product overall.
Each model is supplied with a bespoke installation kit as standard and features an intuitive keypad for quick setup, allowing users to simply set the time, water hardness, and preferred regeneration cycle.
 
The installation of your new water softener is relatively straightforward. However, we would recommend that either a qualified plumber or a person with relevant plumbing experience carries out the installation.
Backed by a comprehensive 5-year parts and 2-year labour warranty, plus free at-home commissioning, the WS 455 offers peace of mind alongside everyday luxury.
