5 Points to Remember When Buying a RO System
The first thing you need to know is that all RO Systems work the same way, look similar and have the same basic components. The only major difference is in the quality of the membranes and filters used inside the equipment. You cannot compromise on this last part because this is where the real magic happens, where undrinkable water transforms into something you can confidently serve your family at the dining table.
Do not feel shy to ask how the system removes total dissolved solids (TDS) from tap water. Ask to see a demonstration. If the company is not confident about the effectiveness of their equipment, you will not find a person standing by to demonstrate how superbly their RO system extracts negative substances (see above for list of such substances).
The operating specs will list the quality of the membranes and filters used, so be sure to do a bit of homework on this before heading out to shop.
While you are at it, get some data on how to check quality for incoming water pressure and water temperature in RO systems. All these factors help determine the overall excellence of the product and will help you shop better.
Here are some of the key terms you should know when dealing with RO components: Replacement Filters (for both residential and commercial systems), Membranes (for both residential and commercial systems), Replacement Parts (check all the components you have with your current RO system and make sure you know where to purchase replacements if required).
Component names to know about RO systems (listed in order of water flow):
• Cold water line valve
• Carbon filter
• Reverse Osmosis membrane
• Post filter
• Automatic shut-off valve
• Check valve
• Flow restrictor
• Storage tank
• Drain line
3.Amount of Treated Water Needed
How much purified or treated water you need is determined by either Point-of-Entry (throughout the house) or Point-of-Use (a faucet system). This in turn influences how much water is required per day, which means you will need to shop for an adequately sized holding tank, pump, and membrane.
Timely replacement of filters and membranes and monitoring water quality are two factors to consider. High capacity Point-of-Entry Reverse Osmosis systems can increase your water bill, so choose them only when you know you absolutely need such high water capacity at home or office.
Selling anywhere from $200 to over $2000, you need not be worried about price as much as you need to be about quality, treatment requirements of the RO system, and purified water capacity.
Why these systems are expensive compared other types of filtration equipment? These are the best home water filtration products and quality is top notch. The more you pay the more the quality, but of course this can vary and sometimes you will find a slightly cheaper RO system has better VFM (value for money) than a costlier one. However, they are still reverse osmosis systems.
