Under-Sink Sentry Wellness System:

What does the Sentry Wellness System include?

The Sentry Wellness System includes:

  • 2 clear housings pre-installed on a mounting bracket
  • 1 Catalytic Carbon Filter
  • 1 Trappsorb Drop-In Filter
  • 1 in-line pressure relief valve (PRV)
  • 1 3/8” tubing for cold water-to-inlet connection (with PRV installed in-line)
  • 1 3/8” tubing for outlet-to-faucet connection (with male brass fitting)
  • 1 wrench
  • 2 screws for mounting the system

The only additional items you need in order to install the system are an adjustable wrench and a drill.

How does the Sentry Wellness System work?

The Sentry Wellness System is an in-line water treatment system designed to work with cold tap water. In the installation video, you will see that our system goes between the cold-water valve and the cold-water line so that when the faucet handle is turned 100% to the cold side, the water will pass through our treatment system before coming out of the faucet.

When the cold water goes through the Sentry Wellness System, it experiences 5 stages of treatment that removes harmful toxins from the water and enriches it with good-for-you minerals. Through this treatment process, you get healthy, clean, great-tasting drinking water straight from your tap!

What are the 5 stages of water treatment?

With the Sentry Wellness System, your water goes through 5 stages of water treatment to ensure you get the cleanest, best-tasting water possible.

  • Stage 1: The Sediment Wrap encapsulates large solids like dirt and debris up to 5 microns in size.
  • Stage 2: Catalytic Carbon removes Chlorine, Chloramines & VOCs.
  • Stage 3: CT Resin softens water and neutralizes soft and hard scale.
  • Stage 4: Trappsorb Media increases pH by boosting alkalinity using Magnesium Oxide.
  • Stage 5: Magnesium-Coated Catalytic Carbon removes fluoride, arsenic, PFAS, PFOS, and Pharmaceutical VOCs as well as sweetens water for improved taste.

What toxins does Sentry Wellness System remove?

The Sentry Wellness System removes ammonia, lead, fluoride, cyanide, copper, chlorine, chromium, arsenic, sulfates, pesticides, bacteria, PFAS, PFOS, and Pharmaceutical VOCs. In addition to removing harmful toxins, our system also enriches the water with essential nutrients like calcium, magnesium, and increased pH for on-demand alkalinity.

You can also check out these results of independent testing performed on a sample of Mesa, Arizona tap water treated with our system.

What's the difference between the Sentry Wellness System and an RO System?

Simply put, the Sentry Wellness System removes all the bad stuff and replaces it with the good stuff so you have clean, healthy, great-tasting water.

Reverse Osmosis is a purification process that uses multiple carbon blocks and a semi-permeable membrane to filter out contaminants and sediments. While this process is effective at purifying water, it also strips the water of good stuff like minerals. Reverse Osmosis systems also tend to take up quite a bit of space, which isn’t ideal for under-sink systems.

The Sentry Wellness System uses 5 stages to filter your water that not only removes harmful toxins and neutralizes soft and hard scale, but also enriches the water by boosting alkalinity, calcium, and magnesium. The Sentry Wellness System is also smaller than your standard RO system, so you can still use your under-sink space for other purposes.

Check out all the differences in this comparison chart.

How does the Sentry Wellness System treat recycled water?

The Sentry Wellness System utilizes several types of filtration media, including Magnesium-Coated Catalytic Carbon. This special type of media is able to filter out hard-to-remove organic pollutants found in recycled water, including PFAS, PFOS, and Pharmaceutical VOCs.

Is there data to back up your claims?

Yes! The Sentry Wellness System has been independent lab tested by Aquatic Consulting & Testing, Inc. for its effectiveness against water treated in Mesa, Arizona. See a summary of the results here or view the full report here. See a summary of the Tempe results here or view the full Tempe report here.

Additionally, samples of water from East Palestine, Ohio were independently tested by Summit Environmental Technologies, Inc. This testing shows that no amounts of vinyl chloride were detected in the water sample treated with the Sentry Wellness System. See a summary of the vinyl chloride results here or view the full report here.

Why is there a Prop 65 warning on your product?

Out of an abundance of caution in order to be compliant with CA Prop 65, Sentry Wellness System products include a Prop 65 warning on the product labels. During the manufacturing process of the Mounting Bracket, this single part is powder-coated with an ingredient listed in the Prop 65 List. This part of the Sentry Wellness System simply holds the system in place and does NOT come into contact with your water at any point during the treatment process, which means there is no risk of contamination or harm to your health. In fact, the Sentry Wellness System is made with NSF-compliant components, which means they have been rigorously tested by a third party for quality, performance, and safety.

What if I have water pressure above 70 psi?

The Sentry Wellness System includes a pre-installed pressure-relief valve to ensure that your system will function properly, regardless of your home or apartment's water pressure. The pressure-relief valve also protects against spikes in water pressure.

I just installed my system, why is my water pressure so low?

You may notice a slight decrease in water pressure right after installing your water treatment system. As your system normalizes, excess air is pushed out, which temporarily decreases your water pressure. This should resolve within a few days of use and your water pressure will go back to normal.

If you're experiencing significantly reduced water pressure, it's possible the excess carbon and trappsorb dust are clogging the filters. To fix this, simply flush the filters by turning on the faucet and then switch back and forth between hot and cold for up to 5 minutes.

How often should I replace my filters?

To ensure optimal filtration and water treatment, we recommend you replace your Trappsorb Drop-In Filter and Catalytic Carbon Filter once per year.

What kind of maintenance does your Whole House System require?

Fortunately, maintaining your Whole House System is easy!

First, set a reminder to replace your Whole House Tank in the future. To ensure optimal filtration and water treatment, we recommend you replace your tank every 5 years for the standard size and every 7 years for the XL size.

Then, familiarize yourself with the Regeneration Timer on the Whole House Tank because there may come a time when you need to reset it. Every 4 days, a regeneration process occurs in order to keep the system running smoothly. This process is meant to happen at a time in which there is no water demand in your home (typically in the middle of the night). If you were to try to use water during the regeneration process, such as taking a shower or washing your hands, you may notice a temporary loss of water pressure until the process is complete. In the event of a power outage or breaker trip, it’s important to check the timer and ensure it is set to regenerate at a time when there is zero water demand.

That’s it for maintaining your Whole House System! For the included under-sink Wellness System, be sure to replace those filters once per year.

What can I expect for the regeneration process and how much water is used?

The Regeneration Head on the Whole House Tank will pump on average for 8 minutes, up to 3-4 gallons per minute, every 4 days. Be sure to follow plumbing codes.

My Whole House Tank is still pumping out water from the regeneration process and it’s been more than 15 minutes. What can I do?

Contact us right away so we can help. To avoid loss of water pressure and possible concerns with the backwashing process, turn off the tank by opening up the bypass valves and reach out to us by phone at 1-833-377-3817 or by email at CleanWater@SentryH2O.com for next steps.

What do I do when I need a new tank for my Whole House System?

To ensure optimal filtration and water treatment, we recommend you replace your Whole House Tank every 5 years for the standard size and every 7 years for the XL size.

When that time comes, simply order your replacement tank by contacting us by phone at 1-833-377-3817 or by email at CleanWater@SentryH2O.com.

Please ensure you order the correct tank size: Standard for homes up to 2,500 square feet or XL for homes larger than 2,500 square feet. If you're uncertain which size system you have, check the label on your current system or contact us so we can help.
