Services
Water Softeners
Our ion exchange water softeners remove calcium, magnesium, and iron to prevent staining and scale buildup. Systems improve soap efficiency, extend appliance lifespan, and enhance hair/skin quality. We recommend solutions based on water test results and household usage patterns.
Arsenic Removal
We implement specialized filtration systems to address both arsenic-III and arsenic-V contamination. Our solutions meet EPA standards for levels exceeding 10 ppb, combining effectiveness with long-term cost efficiency for residential well water systems.
Well Pressure Tanks
We install Well-X-Trol pressure tanks that maintain consistent water pressure while reducing pump wear. These systems prevent sudden pressure drops and extend well system longevity, backed by a 7-year limited warranty.
Radon Removal
Our Prescott Bubble-Up systems remove over 99% of radon from water through aeration technology. Units safely vent gas outdoors, protecting households from exposure during drinking, cooking, and showering activities.
Water Testing
We conduct comprehensive water chemistry assessments including hardness, TDS, chlorine, and contaminant levels. Testing identifies treatment needs and verifies system effectiveness, using certified lab partnerships for specialized analyses.

I had a Friot water softener system installed in my home in 1987, because of mineral deposits staining clothing, pipes, sinks and toilets. Other than replacing the salt used to keep the system running I have only had two minor repair calls. This product has served our family very well for 30 years. The Friot's are pleasant to work with, professional and respond quickly to any service call you may have. In this day and age, it is wonderful to find such professional and competent service.

Great company, and Paul is a great person. I bought a home in which the previous owners had already been using his service, so I decided to keep him. Not only was his service excellent, but he gave me numerous excellent referrals for other local trades people.

I was looking to have a water filter added to our home. The owner came out, tested our water, explained his findings as he was testing, and after looking at our water and our basement setup, suggested that it wouldn't be worth it to us to install a system. He didn't charge us a penny, just gave us the results and recommended against an install. If you're thinking of using a company to test your water and quote you a job, I'd trust this guy!
