CastleGuard Water Systems is a comprehensive water treatment manufacturer offering top-tier performing products with decades of proven performance in the industry.
We have a firm belief that every home should be “guarded” and protected from the damaging effects of hard water and that every family should be protected from the harsh chemicals found in municipal water supplies.
More than 80 percent of us live in communities supplied by city water, while the remaining 20 percent rely on wells located on their property. These two water sources come with their own inherent issues—chemicals, hardness, or both.
Our Commitment
The owners of CastleGuard Water Systems have over 30 years of experience in the water treatment industry.
Our experience is the critical difference between companies designed to sell you products you may not need and a company that hires trained professionals dedicated to providing the solutions you need to achieve the best possible water in your home.
We want the best for you and offer top-tier products designed to protect both your family and your home.
Our Quality
CastleGuard Water Systems understands that investing in water treatment is a serious decision.
We have carefully vetted our designs, media recipes, and suppliers and have chosen to offer top-performing products made in the USA whenever possible.
Only when a non-USA-made product outperforms available USA-made products will we offer it on our site.
Our leadership has extensive industry experience and long-established relationships with suppliers around the world, helping ensure you receive the best possible solution for your investment.
Looking to the Future of Water Treatment
Many of the problems affecting our water supply stem from aging infrastructure.
You may have read about or experienced concerns involving PFAS, lead, arsenic, and other contaminants affecting cities throughout the United States.
These concerns aren’t limited to municipal water. Wells supplying water to millions of Americans can also face challenges. Pesticides and chemical runoff from businesses can make their way into the soil and eventually into private wells.
CastleGuard has mapped out these issues and can provide solutions designed to address these water quality concerns, giving you the peace of mind you deserve.
Welcome to the CastleGuard Water Family
At CastleGuard Water Systems, our goal is simple: provide dependable water treatment solutions backed by decades of industry experience, quality products, and a commitment to protecting your family and your home.
