Questions and Answers for ISPRING 7-Stage Under-Sink Reverse Osmosis RO Drinking Water Filtration System with Alkaline Filter and UV Filter, NSF Certified

A:  Hi Mel86, Unfortunately all RO Systems do incorporate a waste water/pure water ratio and will have some amount of waste water. We have an Ultra-filtration system model CU-A4 that we would recommend you take a look at. This system does have an ultra-filtration membrane and does not have a waste water line. Thank you, iSpring Water Systems LLC

A:  Hi, Yes, our unit model RCS5T has a drain ratio of 1:1 and does not require a storage tank.

A:  Hi Sjames, This system comes with a 4 gallon tank with a 3.2 gallon capacity. The tank will actually hold about 2.5 gallons of water since the tank has an internal air bladder that does take up some space in the tank. Thank you, iSpring Water Systems LLC

A:  Hi Ray, Yes the contaminants Iron and Manganese are removed/rejected by the reverse osmosis membrane (Stage 4) filter. Thank you, iSpring Water Systems LLC

A:  The water comes out the same temperature that it went into the system.

A:  Hi Johnny5, The system is always connected to your cold water supply so the water should come out the same temp as the source water you are connected to. Please let us know if you have any additional questions. Thank you, iSpring Water Systems LLC

A:  There is a brochure in the package which gives a 1-800 number with a real person that answers... They even sent me some free filters...check it out....

A:  Hi reynaldo, The filters on the system have different replacement schedules so some filters need to be changed more frequently. The stages 1, 2, 3, and 6 are recommended to be changed every 6 months. The stage 4 reverse osmosis membrane is changed one every 2 to 3 years, and the stage 5 filter and Stage 7 UV bulb are recommended to be changed once a year or once every 12 months. Please see the filter pack links below for your 7 stage system. https://www.homedepot.com/p/ISPRING-LittleWell-7-Stage-UV-Alkaline-Reverse-Osmosis-2-Year-Filter-Set-F21KU75/206605218 Thank you, iSpring Water Systems LLC

A:  there is not enough details of usage in your question to answer it reliably. You should figure out how many gallons your using on a daily basis on average. If you like to use a lot of water than you will need a faster 7 stage RO system; I am only one person using it. my brother has a similar system for 4+ people and he has moments where it is not large enough volume Look at iSpring website or Home Depot online for larger systems. they are out there. However, if you intermittently use a lot of water, I recommend you bottle during your low usage times. so when you need a lot of ice, there will be plenty from this system I have. I already have a 5 gallon water bottle with a spigot at the bottom for my future social needs.I may even get a few more. I hope you got help from this.

A:  Hi Rob, Yes the system can handle 2 ice makers and a faucet. The only time you may have a loss in pressure to the 3 outlets would be if the system is more than 15 Feet away from the 2 ice makers and faucet. Please contact us if you have any questions regarding the process. Thank you, iSpring Water Systems LLC

A:  yes

A:  Hi Kamil, Yes you can install in a basement but you need to be within 15 feet of the RO faucet and sink otherwise you may have a loss in water pressure to the faucet. Thank you, iSpring Water Systems LLC

A:  Yes you can if the water pressure is enough for it to reach the water tank reservoir. It may take a little longer to fill the water tank

A:  You can install this anywhere. You might need to buy the pump depending how far you are running the line. Don’t forget you need to install by a drain
