We needed to replace our large 100 gal water heater (4.5 Ba house) and called Castleeworks when some slight leakage was visible in the drain pan. Great same-day service by Salvador Vidales, who provided the price estimate, consulted with us on options, and got us an additional discount because we were replacing with the exact same brand that they usually install, so no new major piping was rquired other than the usual new connectors. Waived the delivery fee for the new unit which was in Pomona several hours away on high traffic congestion day.. Salvador was also the installer, very capable and workmanlike. Had the whole worksite set up and old unit ready for removal when the delivery/installation guys arrived on the hottest day of the year. When the new alumuinum drain pan got dented in the installation on our raised pad which didn't look good, he pro-actively had the team pull the new unit back off and installed another replacement drain pan to make sure we were happy with the results. After the delivery guys left when the unit was in place, he worked for several more hours finishing at 7 pm. Showed good workmanship, gave us good advice. We were very happy with Salvador and the company so far at this point. Obviously the proof of the pudding will be in the new unit and our service contracts and warranties, but we're off to a very good start and would highly recommend based on this experience on Day One!

I am more than satisfied with the service I received from Castleworks Home Services. From taking my phone call after hours when I discovered that my water heater was broken and leaking, and scheduling an appointment for the very next day… to keeping me updated on the estimated arrival time of my technician including a text with his full name and photo ID was truly impressive. But what was even more impressive is the actual service itself. Justin, the technician, was extremely easy to work with. He was knowledgeable, polite, explained everything, answered all of my questions, and completed all of the work in one visit. I couldn’t ask for a better experience and highly recommend this company! 5 ⭐️⭐️⭐️⭐️⭐️

We have just had 2 excellent experiences with Castleworks. Picked up the phone right away and was great with communication via phone and text to keep us informed as to when our technician would be out. And Justin the technician himself was absolutely amazing. Knowledgeable, worked clean and quick. We had such a good experience we ended up calling them back out right away for another issue with A/C that was long overdue and had another great experience with Brendan. So hard to find reputable companies that do what they say and that you can trust. Fully recommend them. Save their number!

James Skresvig went above and beyond for me. He even changed a hose for me, completely unrelated to the job he came to do, just to help me out because I didn't have the right tool. He answered all of my questions and was very good at explaining their services without overselling anything - more like explaining options.

Besides getting our water heater running, James was very knowledgeable and gave me useful information about upgrading to tankless. Would definitely use again!

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.
