Q: Will I need a plumber to install my 300-Series system?
A: The PWS™ BEV-300 systems ship with all the accessories necessary for installation, including a detailed, illustrated manual. In most cases the system can be installed without the help of a plumber.

(Best viewed with high speed connections.)
However, if the idea of drilling holes and using wrenches in (sometimes) difficult to reach spaces in something you would be uncomfortable with, we suggest you secure the services of a plumbing professional.
If you do hire a plumber, be sure they take 3 - 5 minutes to review the Installation & Maintenance video before they begin. This animated guide will help the plumber understand, very quickly, just how easy the installation is. Unless you have a very odd under-sink cabinet, there should be no reason for a plumber to take longer than 60-90 minutes to install one of our systems.
Q: How long will my sediment pre-filter last before it needs to be replaced?
A: Under typical city water conditions, the pre-filter is designed to function properly for 12 months, and should be replaced annually. Sediment concentrations vary greatly between municipal systems so there is no way of determining the lifetime of a filter without knowing more about the feed water. In some cases, it may be necessary to replace the pre-filter more frequently.
Q: How long will my GAC pre-filters last before they need to be replaced?
A: Your PWS™ BEV-300 system has been designed to operate within the wide range of feed water conditions. These conditions vary greatly across municipalities, so it is difficult to state precisely how long your pre-filters will last. We have designed the systems so that under the most extreme conditions your pre-filters will still be performing correctly after 12 months of use. Following an annual replacement schedule will insure your system is consistently performing as designed and producing extremely pure water which meets the rigorous Vincent (BEV) standards for bio-compatibilty.
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-filters 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: Does your system turn itself off when the tank is full?
A: Yes, the300-Series systems have an automatic shutoff feature, which also turns the system back on when the water in the tank drops below a certain level.
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 the twin carbon pre-filters. 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 home, 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 (or when greater production capacity is desired), the PWS-BP-300 booster pump is the solution. This 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: Our home is on a private well, will the PWS™ BEV systems work in my situation?
A: Yes, our systems are regularly installed in homes with private wells. We encourage you to consider adding a PWS-BP-300 booster pump to your system, as there are many instances where the minimum pressure in your well's storage tank is not high enough. You can also consider having a plumber increase the minimum pressure in your storage tank.
Adding a booster pump will allow your system to operate at peak efficiency - both in terms of production and rejection rates.
Q: Why is your system more expensive than standard reverse osmosis systems?
A: Our systems, which include reverse osmosis as one of three purification methods, offer several significant advantages:
