Our previous water heater cracked due to the age of it. We had our previous one for 18 years. Chris Dohrer was the technician assigned to us he was very knowledgeable and efficient while replacing our old water heater. He explained all our options and cost associated to each one. We're thankful to Castle Works as well for scheduling the visit on Labor day and would recommend them if you needed repair or inspection in a pinch.

Castle Works has fantastic employees and service. They give you a returning customer discount and Or Military discount that make price’s affordable. I talked with Jessica who was friendly from the moment she answered the phone and she got a professional technician to come out to the house within an hour an 1/2. Miguel was amazing! He checked everything thing out before quoting us a price. He had everything in his truck! We didn’t have to wait until a week day to replace the tank! His work was extremely clean and time efficient. He explained everything! Everything is up to code too now! Hope not to see you for another ten years! We got 13year on our last one! However, if something does go wrong I’m calling you guys! Thank you, Castleworks! Your a top notch Company!

CastleWorks is a great company with a great staff, beginning with the gentleman, Joshua, who answered our call to the young lady who called us to let us know that their technician, Chris Dohrer, was on his way. Chris explained everything simply and clearly to my husband and me, and told us what our options were. Chris is a hard-working, kind, and cheerful young man. He did everything that he said he would, and left everything in a neat manner. He put our old water heater in a place out-of-the-way and said that the service technician who was coming on Monday to put in the new tankless water heater would take the old one away because their truck had more room. We would highly recommend CastleWorks Water Heaters to others who need theirs replaced or repaired. They have a great team working together.

excellent work and technically very high level of plumbing.

With a HALO 5 water filter, you can benefit from:

  • Better-tasting water for cooking, bathing, and drinking
  • Water with no discoloration or strange smells
  • Reduced dryness and healthier skin, hair, and nails
  • Fewer potential toxins putting stress on your digestion or immune system  
  • Longer lasting and better-performing appliances, plumbing, and drainage systems

Find out what life is like without unpleasant chlorine odors, murky water colors, unpleasant tastes, and skin irritants in shower and bath water. When you install a HALO 5 unit, you get a comprehensive, whole-home water filtration system that can operate self-sufficiently without maintenance for the next decade. 

How Does the HALO Water Filter Work?

The HALO 5 water system provides you and your family with soft water using a multi-reversing magnetic field and five filtration stages, including: 

  • STAGE 1: Granular Activated Carbon (GAC): GAC helps remove various contaminants, including dyes, gasses, pesticides, disinfectants, heavy metals, bleach, lead, and more.
  • STAGE 2: Centaur® High Activity Carbon (HAC): HAC keeps water (of varying pH levels) chlorine-free and ensures it has no discernable taste or odor. 
  • STAGE 3: Filter-AG Plus®: This non-hydrous media removes sediments from water more efficiently than more common granular media.
  • STAGE 4: High-Density Garnet Filter Media: As a high-density water filtration media, the garnet filter removes fine particulate matter.
  • STAGE 5: HALO Ion Inline Water Conditioner: The HALO ion conditioner reduces chlorine, chlorination, and chloramine by-products by treating household water to dissolve and prevent scale.

HALO 5 System FAQs

What Is the Maintenance Schedule for the HALO 5 System?

There is no maintenance schedule for the HALO 5 filter. This product is maintenance-free but requires professional installation to ensure all components are connected and working properly. 

How Long Does the HALO Water Filtration System Last? 

The carbon media used to treat your water can last up to 8 to 10 years for a family of four using an average of 146,000 gallons of water a year. The HALO 5 system also comes with a lifetime limited warranty that covers the tank, HALO ion water conditioner, and control head.

Can You Install HALO 5 Systems for Businesses and Commercial Properties?

Yes! HALO 5 Water Filters are popular for commercial buildings across a number of different industries where maintaining consistently high water quality is essential. Some industries where it is popular include: food and beverage, hospitality, healthcare, irrigation, and beyond. 

Can the HALO 5 Water System Be Installed for the Entire House? 

The HALO 5 system is a whole-house water filter system designed to treat water as it enters from your water service line. This means all water entering your home will be thoroughly purified to remove contaminants and only filtered water will flow from the tap.

Can the HALO Filtration System Benefit Household Appliances?

Yes, it can. Unfiltered water can carry sediments to your large appliances (dishwasher and washing machine) and small appliances (coffee maker and ice maker), causing reduced efficiency and poor performance. With the HALO filter, you can experience less wear on components from chlorine, scale, and detergent buildup.  

Answering Common Questions About Water Quality 

Can Unfiltered Tap Water Contribute to Dry Skin, Hair, and Nails?

Yes. Unfiltered tap water can result in dry skin, hair, and nails due to minerals like calcium and magnesium. Hard or unfiltered water can also exacerbate pre-existing health conditions and create various sensitivities. According to the National Eczema Association, mineral-rich water can “impact eczema symptoms and introduce atopic skin conditions early in life.”

Signs your unfiltered water could be negatively affecting your health include:

  • Thin, cracking, or splitting nails
  • Dry, inflamed, itchy, tight, or flaky skin
  • Dull-looking, frizzy, or brittle hair

Is Fluoride in Tap Water Linked to Any Health Risks?

Fluoride is typically associated with good oral health and reducing tooth decay. However, high exposure to fluoride-laden tap water has been linked to:

  • Dental fluorosis, which is a condition that causes white spots on tooth enamel
  • Skeletal fluorosis, or a weakening of the bones
  • Neurological problems with a possible connection to cognitive impairment in children

Keep in mind that research on the effects of fluoride on the human body is limited, and some of the evidence is inconclusive. If you suspect you have high amounts of fluoride in your tap water, contact us to learn about the benefits of the HALO 5 filtration system. 

What Does PFAS in Water Do to Your Body?

Perfluoroalkyl and polyfluoroalkyl substances (PFAS) are synthetic chemicals that have been used in various products for decades, including pots and pans, food packaging, paints, and cleaning products. PFAS are heat, water, oil, and grease resistant, making them perfect moisture barriers. A more apt description for PFAS is “forever chemicals” because it takes years for them to break down. 

However, long-term exposure to PFAS in water could cause changes in the following:

  • Cholesterol Levels
  • Liver Enzyme Levels
  • Hormone Levels
  • Infant Birth Weight
  • Immune System
  • Certain Responses to Vaccines 
  • Risks of Prenatal High Blood Pressure (Preeclampsia)

Why Does My Tap Water Taste Bad?

There are several factors that can contribute to bad-tasting water, including:

  • Organic Matter: Organic impurities like algae and dying leaves can make your water taste muddy or earthy.
  • Metals: Pipe corrosion or copper, iron, or lead plumbing can leach metals into your water, causing a metallic taste. 
  • Minerals: Minerals like sodium sulfate, calcium, and magnesium may cause unfiltered water to taste salty or chalky. 

A water quality issue can be addressed with the high-performing and long-lasting HALO whole-house water filter. Our CastleWorks technicians are trained and qualified to install this effective product for your peace of mind.
