What is reverse osmosis water systems?

Reverse osmosis (RO) is a water purification process that uses a partially permeable membrane to filter out impurities from drinking water. In reverse osmosis, an applied pressure is used to overcome osmotic pressure, a colligative property that is driven by chemical potential differences of the solvent, a thermodynamic parameter. The result is that the solute is retained on the pressurized side of the membrane and the pure water is allowed to pass to the other side. To be "selective", this membrane should not allow large molecules or ions through the pores, but should allow filtered clean water to pass freely.

How does a reverse osmosis system work?

A reverse osmosis system reduces sediment and chlorine from water with a prefilter before it forces water through a semipermeable membrane to reduce dissolved solids. After water exits the RO membrane, it passes through a postfilter to filter the drinking water before it enters a faucet.

How long do reverse osmosis filters last?

The life of the filter element of our machine depends on the two indexes of service time and pure water after filtration. As long as one of them reaches the upper limit, it needs to be replaced. The first stage front compound filter element is recommended to last for 6 months or to filter 550 gallons of pure water. The second stage RO element is recommended to last 24 months or to filter 2200 gallons of pure water. The third stage rear carbon rod filter is recommended to last 12 months or to filter 1,100 gallons of pure water. Due to the different water quality and water consumption of each house, the actual replacement time of the filter element is not consistent. The actual use situation shall prevail. When the filter element needs to be replaced, the prompt light on the machine and the lamp ring of the faucet will prompt through the color change. You can replace it according to the prompt, which is very convenient.

Is this under sink reverse osmosis system unit suitable for well water?

We do not recommend using well water as source for our RO systems.
The reasons are as follows:
1. Large particles.
Compared to municipal tap water, the well water is rich of large particles, which will clog the filters easily, and shorten their lifetime significantly.Please note that the filters will still need to be replaced more frequently, even if you have added a pre-filtration system.
2. Composition
The well water has very complicated compostion, and some of them (apart from the large particles) can cause the filter or internal valve to be clogged and prevent the RO system from normal performance.
3. Water pressure
The well water may not provide the feed water pressure that the RO system requires (14.5 psi min.). Furthermore, the water pressure will be even lower after passing through pre-filtration systems.

What is the minimum water pressure to operate this unit?

The rated water inlet pressure of the machine is 14.5-87psi. It can work properly within this range.

Is the water line hose 1/4" or 3/8"?

Inlet tubing: 3/8", Outlet tubing (connect with RO faucet): 1/4", Feed water adapter: compatible with 3/8" and 1/2" water line.

What does Pure to Drain Rate mean?

The undersink reverse osmosis water filter relies on a semi-permeable membrane to filter out impurities from drinking water. When the tap water is compressed through the RO membrane, it produced pure water and waste water. The ratio of pure water to waste water is called wastewater ratio. 1:1 wastewater ratio means 1 gallon water is wasted per 1 gallon purified, and 2:1 wastewater ratio means 1 gallon water is wasted per 2 gallon purified. The higher the wastewater ratio is, the less waster water produced during the filtration process. During the use of RO water filter, the actual ratio might be lower than the labeled, depending on many factors such as water quality, pH, pressure and temperature.

Kind notice:
Please refer to this diagram and be informed that you need to drill a hole on your countertop to place the smart faucet (No need for this step if your countertop already has a hole). Besides, an adapter will be installed on your household water tubing to connect to RO system’s wastewater tubing and input water tubing.
Electricity is required to run the RO system.
We do not recommend using well water as source for our RO systems. We do not recommend connecting tankless RO to a refrigerator or ice maker.
It's highly recommended to install our RO system with components provided by Waterdrop. Installing the system with any parts or accessories that are not provided by Waterdrop may cause the system to malfunction or shorten the lifetime of the system/filters.
Protects each baby's health
Newborns are very delicate. Compared to tap water, RO water is purer, cleaner and more suitable for babies. Milk powder made by RO water is easier to be absorbed.
