I note your ceramic filters can remove bacteria, what are the differences between this filter and an RO system?

Our ceramic filter is a 0.5 micron filter designed to specifically remove bacteria like e.coli, cryptosporidium and cyst. It can also reduce chlorine and lead from water. Our reverse osmosis systems uses a 0.0001 micron filter so it is designed to remove all of the contaminants above and other harmful contaminants like Fluoride, Arsenic, Nitrates, Heavy Metals, and many more. Our RO systems uses multiple filters to remove a complete range of contaminants and impurities versus a single ceramic filter which removes specific contaminants.

What is the maximum number of dispensing points (faucets) your reverse osmosis system allows? Also is there a limit to how many appliances that we can connect the output of our R.O. system to? (I have ice makers and humidifiers)

The maximum output for a standard RO unit is 3 regardless if it’s faucets or appliances. However, we do carry RO systems that can support more than 3 outputs or longer distance runs. Please contact us for details.

We have a church with about 30 people during regular weekdays and we have about 200 people doing weekends, what system do you recommend us to install?

From the information you have provided, based on 200 people drinking one cup of water each during peak times, we recommend using our Lite Commercial 180 or Compact RO 250gpd.

Lite Commercical 180gpd http://www.freedrinkingwater.com/light-commercial-detail.htm
Compact Commercial 250gpd http://www.freedrinkingwater.com/compact-commercial-detail.htm

If you are able to provide some additional information, we can better determine a size for the unit.

  1. Are you using city or well water?
  2. How many gallon of pure water do you need per day?
  3. During peak times, how many gallons of water do you need at one time?
  4. Do you have a water report for us to review?

What is the average life time of your reverse osmosis system?

The actual time is depended on your water conditions and if the system is properly maintained. Our Reverse Osmosis Systems are designed to last for 10 years or more as long as system is properly maintained and your supply water contaminant levels is not very unique.

If I already have a whole house water filter system, do I still need a reverse Osmosis drinking water system?

Yes, if you would like to completely purify water for drinking. Whole House Water Filter Systems are designed to reduce specific contaminants like chlorine, sediment, iron, and water hardness, etc, but these units are not effective in removing many harmful water contaminants. Reverse Osmosis systems consist of multiple stages and filters so they effectively remove more harmful contaminants and impurities found in tap water than all whole house filter systems (Ex. heavy metals, fluoride, VOCs, arsenic, radioactivity, etc). If you want to have the purest, safest drinking water possible, we recommend installing our Reverse Osmosis system.

Is it appropriate to dispense reverse osmosis output water using metal tubes? Why?

It is not recommended to dispense reverse osmosis output water using metal tubes. Because water is known as the universal solvent, metal may leach into the water causing a metallic taste. We recommend using food grade polypropylene tubing to be used as a standard with RO units.

Sometimes I see some gases or tiny bubbles inside the water cup, dispensed from your RO system, yet they seem to disappear in a few minutes. What is that and shall I be concerned?

It is quite normal to see air bubbles in a cup of pure water. This mainly occurs that air can be trapped within the RO system when the unit is first installed or filters are being replaced. As water is turned on and flows through the unit, the air pockets move throughout the system. This can have an effect on the appearance of air bubbles in the water. Ro units are very effective in removing contaminants and impurities, but cannot remove gases from water. The air bubbles you see can be from gases. Gases are not harmful in anyway and should not be of any concern.

Ro units will self purge the air bubbles that can accumulate inside the unit. As you continue to draw water, trapped air will be removed by the water flow and you should quickly see a reduction in bubbles inside the water cup. You can also drain 1-2 tanks of water to quickly purge the air bubbles.

How did you calculate that you can have savings of over $800 for owning a reverse osmosis system? And How did you end up to 2 cents per gallon for reverse osmosis water?

To calculate the savings, bottled or delivered water is about $0.79/Gal. RO water is about $0.02/gal. You saved $0.77/Gal. If you use 3 gallons of purified water per day or 1,095 total gallons per year, you save $843 per year.

To calculate RO water cost, it costs about $55 dollar per year to replace all the filters on the RO system. The average usage is about 2,400 gallons per year. 2,400 gallons divided by $55 equals about $0.02 per gallon.

You said we need to change filters every year, however, we have to not used much water this year, do we still have to replace the filters in one year?

The one year recommendation on our filters is based on average replacement time. If you do not use a lot of water, it is possible for you to have longer life on the filters but we strongly recommended not to over use your filters to preserve the life time of the membrane filter and components. You can consider upgrading to a clear housing on your first stage filter so you can physically see the filter to decide when to change them.

Are there any precautions needed when handling the membrane and the 5th stage TCR filter, during our regular reverse osmosis system’s maintenance?

The reverse osmosis membrane must never be handled by your bare hands. Our hands and skin contains bacteria, dirt and oil. This can damage the membrane and cause pre mature failure. You must use pliers when handling the membrane. Use a pair of pliers to grip onto the plastic tip of membrane, do not touch the leaves or blue outer wrapping of the membrane. Do not apply any beach or cleaning solution to the membrane in anyway.

The 5th stage TCR filter can generally be handled by your bare hands. Before reconnecting the plastic fittings at both ends of the 5th stage filter, you can apply some mild bleach solution to rinse the plastic fittings, tube ends and 2 ports on the filter. Make sure the Flow -> on the filter is pointing to the pure water output line.

You must discard the first 1-2 tanks of water as both the membrane and 5th stage filter needs to be flushed out before use. The 5th stage filter can release some carbon fines at first flush. This is normal and will quickly clear up after the first flush.
