Q: Is the BEV100 system difficult to install and maintain?
A: The BEV100 systems are extremely easy to install—all that is required is replacement of the existing aerator on your faucet with the one provided. This takes only a few minutes. Maintenance is simple and straight-forward as well. You can see for yourself just how easy it is to own and use a BEV100 system by reviewing the Installation & Maintenance video.
Q: How long will my pre-filter last before it needs to be replaced?
A: The sediment and carbon pre-filter in your PWS™ BEV-100 Series system is designed to be replaced annually. Tap water quality varies greatly from location to location, so there is no way to predict individual filter life without knowing more about the water entering the system. Annual replacement will ensure your system operates at maximum efficiency and will extend the life of the reverse osmosis membrane.
Q: How long can I expect the reverse osmosis membrane to last?
A: The reverse osmosis membrane in your PWS™ BEV-Series system will continue to perform to BEV standards for 2-4 years, depending on the quality of the water entering the system. Annual replacement of the sediment and carbon pre-filter will help extend the functional life of the membrane, as will following the flushing procedure as outlined in the owners manual.
Q: How can I monitor the performance of my system?
A:The most effective method of monitoring your PWS™ BEV system is to measure the resistivity (conductivity) of the purified water and compare it to the feed (tap) water. This simple, straight forward test is performed easily using one of the Primo™ TDS meters we offer. This method does not test every BEV parameter, but will provide an indication of the performance of your system.
(Poor rejection rates may be an indication of a plugged pre-filter, so check that filter first.)
Since the PWS™ BEV systems are multi-phase configurations, after two years it is instructive to test the performance of the Reverse Osmosis (RO) membrane separately from the complete system. Our RO membranes can be expected to last 2-4 years, sometimes much longer. We normally recommend replacing the RO membrane every 3 years, but if you choose to monitor membrane performance yourself, you can get the maximum life from the membrane.
Similarly, one may find they can extend the life of the deionization module longer than the recommended annual replacement cycle using a TDS meter. However, the pre-filters should be changed annually regardless of usage scenarios.
A large increase in the production rate is also an indication of membrane failure, and can often be traced to the membrane having been subjected to either hot or freezing water.
Q: Will hot water damage my system?
A: YES! Hot water over 100° F will damage the RO membrane and lead to poor rejection of the contaminants in your water. Make sure to use only COLD water in your PWS™ BEV system.
Q: Does your system turn itself off when the tank is full?
A: No, the 100-Series systems do not have an automatic shutoff feature. The 100-Series housing contains an "overflow gutter" so that excess production flows down the drain via the quick-connect coupler.
Q: Is it normal for a small stream of water to flow from the bottom of the faucet coupler?
A: Yes. To keep reverse osmosis membranes from fouling, water must continuously be washing over the membrane surface, carrying away concentrated contaminants.Your BEV system uses 2.5-3 gallons of tap water to produce one gallon of pure BEV quality water. (Making a full tank of water uses less water than a typical 5-minute shower.)
Q: I have one of the modern faucets with a spray-head/aerator combination that pulls out on a hose, how will your system attach?
A: Our systems ship with faucet adaptors that fit a great majority of faucets, and we have an international adaptor set available as well.
Some spray-head/aerator combination units do not have replaceable aerators, or do not allow enough room for the quick-connect coupler to seat fully when attached. In these cases, a BEV-300 system is a better solution. We do have kits available to allow the more permanent installation of a 300-Series to be disconnected once installed. You won't have to leave your BEV system behind when you move.
Q: How many gallons of tap water are used to make a gallon of pure water?
A: Your BEV system uses 2.5 - 3 gallons of tap water to produce 1 gallon of pure BEV quality water. This translates into less water than a typical 5-minute shower. In normal usage, the amount of water used to produce pure BEV quality drinking water will not even register on a monthly water bill.
Additionally, the brine water which flows down the drain during the course of pure water production has been filtered by our carbon pre-filter. This means the waste water has fewer organic contaminants than the water that originally entered the system.
Q: How should I store my purified water?
A: We recommend using a sealable glass container. Used gallon fruit juice bottles are an excellent choice. We also recommend containers made of 100% LEXAN®, like those available under the Nalgene® brand. If you store or transport your BEV quality water in plastic or polycarbonate containers, be sure to keep the containers out of direct sunlight.
Q: How should I store my unit when not in use?
A: If your unit is out of service for several days (while you are vacationing, for example) no special precautions are required. However, we do recommend you flush the unit for 10 minutes when you return the system to production.
Q: I have very low water pressure in my house (or RV), will your system still work?
A: In order to overcome the natural osmotic force, there must be enough water pressure to drive the reverse osmotic process. This normally equates to at least 40 psi.
When low pressure is a problem, the PWS-BP-100 booster pump is the solution. This elegant, virtually silent pump will boost the feed water pressure to 100 psi, allowing your system to operate at peak efficiency.
Q: How will I know if there is a problem with the reverse osmosis membrane?
A: The best method is to measure the resistivity (conductivity) of the purified water and compare it to the feed (tap) water. You can obtain a resistivity meter from us.
Poor rejection rates may also be an indication of a plugged pre-filter, so check that filter first. A large increase in the production rate is also an indication of membrane failure, and can often be traced to the membrane having been subjected to either freezing or hot water.
Q: Will I lose valuable trace minerals by drinking extremely pure BEV quality water?
A: NO! Tap water is a poor source for obtaining necessary trace minerals. Please take a moment to consider..
1) Inorganic minerals are poorly utilized by the body. The most beneficial and bio-available minerals are obtained from eating plants grown in rich, organic soils.
2) The amount and quality of the minerals in tap water varies greatly from location to location.
3) Even in cities where the tap water contains very, very large quantities of dissolved minerals, you would have to consume huge quantities of water to obtain enough minerals to meet any established minimum daily requirements.
— As an example, the city of Lubbock, TX has what is considered very, very hard water with a high amount of dissolved minerals. With an average of 60 milligrams/liter of calcium, one would have to consume over 5 gallons of Lubbock tap water to meet the minimum daily requirement for calcium. Obviously, the most frequent recommendation of 8 glasses per day (which is a low recommendation in our opinion) has no chance of providing a meaningful contribution to your daily calcium intake. The same is generally true for other minerals.
Q: Why is your system more expensive than other reverse osmosis systems?
A: Our systems, which include reverse osmosis as one of three purification methods, offer several significant advantages:
