World first: Softest Pearl­water with Perfect Taste

What was once a chal­lenge for plumbing profes­sionals, and consid­ered impos­sible without costly, dual-​piping systems, is now a reality thanks to an inno­v­a­tive concept. The BWT One Pipe Power formula ensures that water from a single pipe is soft­ened throughout the entire building and miner­al­ized and filtered in the kitchen for cold drinks. This revo­lu­tionary system elim­i­nates the need for double-​​piping, reducing instal­la­tion time and cost while setting new stan­dards for hygiene. BWT is now a leader in this patented tech­nology that completely trans­forms the approach to drinking water treat­ment.

“Years ago, silky-​​soft Pearl­water from BWT revo­lu­tion­ized the market. Since then, millions of home­owners and building oper­a­tors have enjoyed its numerous bene­fits,” says Andreas Weis­senbacher, CEO of BWT. “Now, with One Pipe Power Pearl­water, we’re taking that success story to the next revo­lu­tionary level. We’ve created a solu­tion that will dramat­i­cally improve people's quality of life, enhance the hygiene and safety of water systems in large build­ings, and contribute to the sustain­able protec­tion of our planet.”

Silky Soft Water meets Perfect Taste

The revo­lu­tionary system features two key compo­nents: the inno­v­a­tive BWT Perla­MAXX or Rondomat duoMAXX soft water systems, which deliver the softest Pearl­water, and the BWT Pearl­water Miner­al­izer Kitchen Set, a smart, under-​sink solu­tion that miner­al­izes the water at the touch of a button. This combi­na­tion ensures that BWT provides the highest quality water for every appli­ca­tion, whether in detached or semi-​detached homes, multi-​unit resi­den­tial build­ings, hotels, offices, or public facil­i­ties.

1. BWT Pearl­water Systems: As soon as calcareous water enters a building via the existing pipe, BWT’s Perla­MAXX water soft­eners trans­form it into ultra-​soft Pearl­water with a hard­ness level of less than 4 °dH. The latest-​generation Rondomat duoMAXX water soft­ener is the first series-​produced unit with full thermal insu­la­tion and a plug-​and-play instal­la­tion concept.

2. BWT Pearl­water Miner­al­izer Kitchen Set – Powered by Mixxo Pro: The BWT Pearl­water Miner­al­izer Kitchen Set can be easily installed under existing kitchen taps and reminer­al­izes the soft­ened water with valu­able minerals – calcium, magne­sium, and sili­cates as well as hydro­gen­car­bonate – at the touch of a button via an elegant chrome remote control. Replacing the miner­al­iza­tion cartridge under the sink, which can process up to 3,000 liters of water, is simple and quick.

Win-​Win-Revolution – For You and Planet Blue

One Pipe Power joins a long list of BWT inno­va­tions with a clear goal: to offer customers enhanced taste, comfort, well-​being, and hygiene while making a sustain­able contri­bu­tion to the planet. Building owners, installers, and oper­a­tors benefit from energy savings, fewer break­downs, and reduced repairs to instal­la­tions and appli­ances. Resi­dents enjoy fewer limescale deposits in bath­rooms, less cleaning effort, and a smoother feeling on the skin, softer hair, and notice­ably softer textiles. Addi­tion­ally, the silky-​soft Pearl­water reduces the need for deter­gents, cleaning agents, and cosmetics, lowering envi­ron­mental impact.

The tastiest miner­al­ized Pearl­water for drinking, enriched with magne­sium, sili­cates, and bicar­bon­ates, promotes well-​being and vitality. With this system, the need for bottled water—whether plastic or glass—is elim­i­nated, saving up to 80% of CO2 emis­sions from trans­porta­tion.

“As part of BWT's mission, ‘For You and Planet Blue,’ we are committed to providing our customers with water quality that they can see, feel, and taste the differ­ence. At the same time, we’re helping protect our planet by reducing the need for bottled water, elim­i­nating trans­port emis­sions, and cutting down on plastic waste. We are espe­cially proud today to present One Pipe Power Pearl­water—a solu­tion that bene­fits our customers, their busi­nesses, and the envi­ron­ment,” said Andreas Weis­senbacher during the presen­ta­tion of One Pipe Power at ISH 2025.
