The Best Water Treatment Systems In The World

There was a time, not so long ago, when people took water for granted. You could drink a glass of water out of the tap, and not worry about it. If you were out, you could go to a public fountain and have a drink, and not worry about it. You could bathe and clean your dishes and clothes without even thinking about the quality of the water in your home.   Unfortunately, that was then, this is now, those days are gone forever. 


Hanish Water Is Here To Help

The WaterCrest is the first and only Whole House Physical Water Processing System that gives you high quality water treatment for your drinking water and scale reduction to protect your plumbing, fixtures, and water using appliances at every tap in your home. It uses no electricity, no moving parts, no chemicals, wastes no water and uses NO SALT.  Little Kid Bathing with Clean WaterYou never have to lift another bag of salt, and you never have to buy bottled water again in your life.  The WaterCrest gives you clean, safe, clear, healthy, great tasting water at every tap in your home.  The WaterCrest treats your water for bacteria, virus, cysts, particulates, metals, contaminants, bad tastes and odors, chlorine, and hardness at up to 18 gallons per minute throughout your entire home.  No other water treatment system can accomplish the same in one small package.  

This is not a slogan, but rather a mission statement that we live by each and every day. We have developed the best water treatment systems in the world that not only provide you and your family with safe, clean water, but at a price you can afford.  Our focus is on creating systems that are efficient, effective, and  environmentally friendly.


I am enjoying our Hanish Water system tremendously. Not only does the water taste delicious, but it is great on the skin. It saves us on money and time. No more water softener monthly bills; no more salt purchases, no more spending gas to the grocery store when water bottles run out, and I can get an additional 2-3 weeks before I need to color my hair. It was a small price to pay for a lifetime of health.
