• "What is Reverse Osmosis?"
Reverse Osmosis is a process in which water is forced by pressure (at least 30psi) through a semi-permeable membrane. The good water passes ("squeezes") through a special membrane while the dissolved and particulated materials are sent down the drain.

• "What type of faucets do the above RO come with?"
Reo Pure units are shipped with either a high spout built-in air gap faucet for certain city codes or a high spout non air gap faucet, your choice. Non air-gap faucet present less problems in the long run. The air gap is built in (underneath) this faucet (for prevention of contamination of the waste touching drinking water). When shopping for reverse osmosis systems, be sure to check what type of faucet dispenser is included.

• "I have an RO system and there is water coming out from underneath the water dispenser faucet. What is wrong?"
More than likely you have an air gap style faucet. This is a safety feature. If there is any kind of clog or kink in the RO drain line, water will come out from under this style of faucet.

• "What if my hardness is greater than 12 grains per gallon?"
If your water is harder than 12 grains per gallon, then it will tend to foul the RO filter prematurely and will void any warranty. This is the case with almost all makes of RO systems. If your water is that hard we would recommend a water softener.

• "I've seen RO that cost less than the ones you manufacture?"
Yes, we could manufacture a lower priced RO as well. If you have spent any length of time looking at our online catalog we know that you have seen how low our prices are. When deciding what RO to offer we decided that lowest priced models aren't necessarily a bargain in the long run. Reverse osmosis systems need new membranes and filters on a regular basis for example. Make sure to compare those prices and ratings as well. Our customer satisfaction rate is very important to us. We think you will agree that buying a "cheapy" unit isn't necessarily a bargain in the long run.

• "My RO continues to run. What is wrong?"
Check the storage tank; it might not have enough air in it. The tank should have between 5-10 lbs of air in it when empty. Too much air will cause an RO to shut off prematurely.

• "We have been considering buying a large 'whole house' RO system. Would the largest RO units that you offer work for our main water line. ?"
Our largest RO is for a whole house application. We offer a line of whole house Reverse Osmosis system for any need.

• "I just installed a new filter cartridge and my water is cloudy/white?"
After you install a new filter (this is the case with any/all brands of filter cartridges) you should run the cold water for a few minutes. Generally cloudy or white water indicates air in the line and this is natural and normal with the replacement of a cartridge. Air will enter in the housing, lines and cartridge. Just run the water for a few minutes and the cloudy conditions will go away. It is always a good idea to run the water free-flowing for a few minutes after installing any brand or type of new whole house filter cartridge.

• "Ok, I installed my RO and have my faucet open but I'm not getting much water. I do hear water running down my drain pipe but I'm not getting much water out of my faucet. What is wrong?"
Nothing is probably wrong (assuming you purchased your RO unit from us). The reason for the tank on residential RO systems is because it takes a long time to produce RO water. The faucet needs to be in the off position and then the tank will (very slowly) fill. On the 26-gallon models it takes at least a day to produce up to 26 gallons. Close your faucet and wait at least an hour and then the tank will be partially full and you can then start to use water. A 26-gallon per day model does not mean that you can use 26 gallons all at once but rather, it can (if all was "ideal") produce up to 26 gallons during an entire 24-hour period.

• "I bought a Reo Pure RO unit 20 years ago and the company went out of business. Can you help me?"
We can cross reference the unit by the model and serial number and provide replacement parts and support for all RP products.

• "How often should I replace my filters and membrane?"
This is a very common question. It depends a lot on your water conditions, water quality and your usage. We believe that in no case (no matter what brand that you have) should you keep the Pre-filter longer than a year (changing it every six months is better) nor the actual RO membranes longer than 4-5 years.
