What is the purpose of the small (1/2" outer diameter), clear, plastic ring included in the parts kit bag?

The ring fits inside the female connector end of the black, plastic 3/8" supply-compression adapter, i.e. tee adapter. If the ring came as a loose part in your parts kit bag, and your plumbing piping/tubing is 3/8", insert the ring into the female connector end of the 3/8" tee adapter. The ring will help to create a tight seal between the female end of the tee adapter and your cold-water supply shut-off valve. If your plumbing piping/tubing is 1/2" you will NOT need the clear, plastic ring to sucessfully complete your installation.

If the female end of the black, plastic 3/8" supply-compression adapter (tee adapter) does not form a tight seal with my cold-water shut-off valve, how can I fix it?

Check inside the female connector end of the 3/8" tee adapter for a small, clear, plastic ring. If the ring is not inside the female connector, look for the ring inside the parts kit bag that came with your Zuvo® Water Filtration System. Once you've located the ring in the parts bag, place it inside the female connector and re-connect it to the cold-water shut-off valve. Tighten the connection to form a tight seal, however, DO NOT over tighten as this could crack the plastic adapter. If you cannot find the plastic ring, please contact us to request a replacement part. If the plastic ring is inserted, and a tight seal still does not form, please contact us for further troubleshooting assistance.

Is it normal for water to continue flowing from the Zuvo beverage faucet once it is turned off?

Yes. Continued water flow for three to four seconds after the Zuvo beverage faucet is turned off is normal. Unlike your main faucet, the Zuvo system is not under constant pressure. Because of this, there is cleansed water downstream of the shutoff valve that drains out of the Zuvo beverage faucet. To avoid wasting water, we suggest turning the Zuvo beverage faucet off just before you've poured the desired amount of water while continuing to hold the glass or pitcher underneath the faucet to capture the additional water.

What is the difference between the Zuvo Water Filtration System and a reverse osmosis system?

The Zuvo Water Filtration System is based on a unique, patented five-step cleansing process including Ozonation, Ultraviolet Light, Photo-Oxidation, Filtration, and Post Filtration UV. Reverse osmosis is a different type of water cleansing process in which high pressure is applied to water when it is on one side of a membrane. Wastewater including contaminants larger than the membrane are retained on the pressurized side of the membrane and the cleansed water passes through the membrane to the other side. Reverse osmosis systems waste a lot water. For every gallon of clean water, 4 to 8 gallons of water is wasted. The Zuvo Water Filtration System does not create wastewater. Reverse osmosis systems have a large clean water storage tank. The Zuvo Water Filtration System has a small footprint that takes up less space under your sink than a reverse osmosis system.

Is my 300 Series Zuvo system operating properly if the indicator light displays a blinking blue light, rather than a steady blue light, once the system is done flushing and the Zuvo beverage faucet is still on?

Yes, a blinking blue light inidicates that the flush system is complete, and the Zuvo beverage faucet can be turned off. The Zuvo Water Filtration System 300 Series Owner's Manual (document ID M060.2_05/11 located at the bottom of page 8 (English) and page 16 (Spanish)) incorrectly states that the indicator displays a steady blue light.

If my 300 Series Zuvo system indicator light or buzzer is stuck in an unexpected state are there steps I can take to resolve this?

Yes, if this occurs turn off the faucet and unplug the Zuvo system, wait 30 seconds and plug it back in. Once you've plugged in the Zuvo system the indicator light and buzzer should cycle through the start-up sequence and the system should begin flushing.

What steps should I take if my Zuvo Water Filtration System starts leaking?

The Zuvo system is designed as a sealed system and should not leak. However, if your Zuvo system begins leaking particularly right after installing it, check to make sure the plumbing connections (cold supply adapter and tubing) are secure. You should not be able to feel or see any water at the adapter or tubing connection points. If there is water leaking from a connection point, turn off your cold water supply shut-off valve and place a towel underneath your sink. If the leak is coming from a tubing connection point, depress the white quick connection using the white plastic spanner wrench that came with your Zuvo system and pull the tubing out of the connector. For a demonstration of this watch the Zuvo Water Filtration System 100 Series Installation Video or 300 Series Installation Video on YouTube.

What is UV or ultraviolet light?

Ultraviolet light (UV) is part of the spectrum of electromagnetic energy generated by the sun. We are all exposed to the UV in sunlight. The Zuvo Water Filtration System uses UV light at the wavelength of 254nm for supplemental germicidal treatment of disinfected public drinking water. The system has been tested and conforms to the NSF/ANSI Standard 55 Class B for reduction of normally occurring non-pathogenic microorganisms. The Zuvo Water Filtration System is not intended for disinfection of contaminated water or water that is microbiologically unsafe.

How often will I need to change my filter?

Standard-capacity and VOC filters should be changed every 3 months, or after 250 gallons of water have flowed through the filter, whichever comes first. High-capacity filters should be changed every 5 months, or after 400 gallons of water have flowed through the filter, whichever comes first. However, water quality and water usage may affect the frequency of filter changes. Monitor your water usage if possible, as it can change seasonally. If you start to see degradation in water flow from your Zuvo Water Filtration System or experience an unusual taste, change the filter. The 300 Series models have an indicator light that tells you when it's time to change your filter. The newer 100 Series models have a buzzer that tells you when it's time to change your filter. The indicator light and buzzer take the guesswork out of changing your filter.

My Zuvo Water Filtration System stopped making bubbles. Is this normal?

It is normal for the Zuvo Water Filtration System to stop producing bubbles when the filter becomes clogged and/or the flow rate slows down dramatically. This is a good indication that it’s time to change your filter. Filters should be changed after 500 gallons, or approximately 6 months, whichever comes first.

Does the Zuvo system require electricity?

Yes. Whether installed on the under counter or on the countertop, the Zuvo Water Filtration System must be plugged into a 110V Ground Fault Circuit Interrupter (GFCI), un-switched electrical outlet in order to function properly.

Back to top »

 

Will the Zuvo Water Filtration System affect my electricity bill?

No. There should be little, if any, noticeable change in your electricity bill as a result of using the Zuvo Water Filtration System. The system uses electricity only when it is on. For the few minutes a day that the Zuvo Water Filtration System is used, it draws just 27 watts of power. By way of comparison, most light bulbs in your home are 60 watts or higher and they are typically turned on for long periods of time when in use.

Is it safe to drink ozonated water?

The Zuvo Water Filtration System produces ozone as a secondary oxidant for treating water in the unit. That ozone is converted into oxygen by the carbon filter before the water is discharged from the unit, ensuring that you get only fresh tasting, oxygenated water from the system. Ozone is commonly used in this way during the process of treating commercially bottled water.

Does your system remove arsenic and/or nitrates from water?

No. Currently the Zuvo Water Filtration System is not rated for reduction of arsenic or nitrates.

Back to top »

 

What is the micron rating or particle size removal of the carbon filter?

The Zuvo Water Filtration System carbon filter is rated at 0.5 micron nominal and has been independently tested to NSF/ANSI standards for the reduction of protozoan cysts such as giardia and cryptosporidium as well as Class I particulates.

Does the Zuvo system take out chlorine in the water?

Yes. The Zuvo Water Filtration System has been independently tested to the NSF/ANSI Standard 42 for the reduction of chlorine and is rated at 500 gallons per filter. The State of California Department of Public Health requires that this be made an “aesthetic” claim (for taste and odor only, meaning a minimum 50% reduction of chlorine for the stated capacity) because it does not consider chlorine to be a harmful chemical. In independent third-party testing the Zuvo system actually reduced chlorine to less than 0.01 mg/L (below the detection limit of the study) for the full 500-gallon capacity of the carbon filter. That equates to a chlorine removal rate of 99% in the water.

Does your filter take out fluoride?

No. The Zuvo Water Filtration System does not reduce fluoride. Our company recognizes that there is legitimate debate about the subject of fluoridation of drinking water, but currently Zuvo Water does not offer a filter that reduces either naturally occurring or added levels of fluoride that meet EPA requirements for public water systems.

Does the Zuvo Water Filtration System take out lead in the water?

Yes. The Zuvo Water Filtration System has been independently tested to the NSF/ANSI 53 standard for the reduction of lead.

Back to top »

 

Is your product certified to NSF/ANSI Standards for Drinking Water Treatment Units?

Yes. The Zuvo Water Filtration System has met all requirements including demonstration that the device has been independently tested to NSF/ANSI Standards for Drinking Water Treatment Units by an accredited third-party laboratory for all claims made against NSF/ANSI standards. Contrary to common belief, drinking water treatment units are not required to be “NSF certified” (i.e. tested by NSF International itself), but they must be independently tested to the applicable NSF/ANSI standards by an accredited, independent laboratory. Though the test standards bear the NSF/ANSI name, NSF International is just one of those accredited institutions.

Can I hook up the Zuvo system to my refrigerator ice maker?

This is a common question we get asked because it is a very appealing to use Zuvo Water to make ice. Unfortunately, at this time the unique design and function of the Zuvo Water Filtration System precludes its use with refrigerator icemakers. The reason is that the icemaker requires a constant pressure water supply, and the water supply downstream of the Zuvo system is only under pressure when the beverage faucet is turned on.

Is the Zuvo system a purifier or a filter? What’s the difference?

To be recognized as a water purifier, a drinking water treatment unit must meet strict requirements for the logarithmic reduction of infectious microorganisms including bacteria, viruses and cysts. Technically speaking, a water purifier must be able to treat water of unknown microbiological quality and, in that water, reduce bacteria by 99.9999% (6 logs), viruses by 99.99% (4 logs) and cysts by 99.9% (3 logs) according to a nationally recognized standard such as the EPA Guide Standard and Protocol for Testing Microbiological Water Purifiers or NSF P231. These very challenging tests set forth parameters that make the test water very challenging and within these protocols, there are additional requirements for the reduction of turbidity (cloudiness), and control of pH and conductivity among other variables. There are few point-of-use (POU) water treatment systems that meet these stringent requirements, so most commercially available drinking water treatment systems, including the Zuvo Water Filtration System, are water filters, not water purifiers.

Can I use another manufacturer’s faucet with the Zuvo Water Filtration System?

No. The Zuvo Water Filtration System is uniquely designed and uses specially adapted Zuvo Beverage Faucets which are only available from Zuvo Water. Faucets intended for reverse osmosis systems and direct flow-through systems will not work with the Zuvo Water Filtration System. The use of a non-Zuvo Beverage Faucet may cause your filtration system to leak.

Back to top »

 

Can I use a Zuvo Beverage Faucet with another manufacturer’s water treatment system?

No. The Zuvo Beverage Faucet is uniquely designed to be used exclusively with a Zuvo Water Filtration System. It uses uniquely designed connections which are not compatible with other water treatment system brands.

How is Ozone generated in the Zuvo Water Filtration System?

UV energy has a germicidal effect, i.e. it disrupts the DNA in microorganisms, thereby inhibiting their ability to replicate. The Zuvo Water Filtration System is tested to NSF/ANSI 55B, the standard for UV reduction of non-pathogenic microorganisms. These are “bugs” in the water that can affect the taste, odor and aesthetic quality of water.

At 185 nanometers, UV energy breaks apart oxygen molecules in air. Because oxygen atoms are highly unstable, some of these recombine with other oxygen molecules to form ozone. Chemically, this is O + O2 = O3. This reaction takes place in the space between the UV lamp and the quartz sleeve in the Zuvo unit. The ozone is then siphoned through a tube attached to a Venturi (a simple device that creates a vacuum from a pressure differential) and infused into the inlet stream of water, where it creates the bubbles that swirl up in the Filtration System chamber. These bubbles are a combination of air and ozone in the gas phase. Some of the ozone is actually dissolved into the water through the Venturi and this is how the ozone has a direct oxidizing effect in the water. When the water containing dissolved ozone passes through the carbon filter, the ozone is “destroyed”, i.e. converted back to pure oxygen.

At 254 nanometers, UV energy has a germicidal effect, i.e. it disrupts the DNA in microorganisms, thereby inhibiting their ability to replicate. The Zuvo unit is tested to NSF/ANSI Standard 55 Class B, the standard for UV reduction of non-pathogenic microorganisms. These are “bugs” in the water which can affect the taste, odor and aesthetic quality of water.

Finally, the Zuvo system employs a process known as photolysis, in which powerful oxidizers known as hydroxyl radicals are produced when UV combines with ozone in the water. This results from the dissolved ozone in the water being bombarded with UV 254 energy as the water swirls up the chamber. So not only is there a direct supplemental germicidal effect from the UV 254 energy, but also there is an indirect effect from the creation of hydroxyls.

What's the benefit of all of this? Healthy, fresh-tasting, naturally treated water. Plus a maintenance-free filtration system that does not foul or allow biofilm to grow on the components that contact water. Biofilms are common with carbon based filters and can be a source of unpleasant tastes and odors.

Is the tubing used in the diverter assembly both BPA and Pthalate free?

Yes, the tubing is both BPA and Pthalate free. In addition, the Zuvo Water Filtration System has been tested and successfully passed the rigorous NSF/ANSI 53 standard for toxicological extractions, meaning that the device does not impart any known harmful chemicals into the water.

Back to top »

 

Are the Zuvo Beverage Faucets lead-free?

Yes. All Zuvo Beverage Faucets meet California Assembly Bill 1953 (AB1953) no lead law for end-use devices intended to convey or dispense water for human consumption through drinking or cooking.

Which water contaminants does the Zuvo Water Filtration System reduce?

A Zuvo standard- or high-capacity filter combined with any Zuvo system reduces the following water contaminants: chlorine taste and odor, lead, cysts (Cryptosporidium and Giardia), tiny particulates and non-pathogenic microorganisms. A Zuvo VOC (volatile organic compounds) filter combined with a Zuvo system reduces all water contaminants that the Zuvo standard- and high-capacity filters do plus VOCs (volatile organic compounds).
