Please Note 1.We do not recommend using well water as source due to its complicated composition. 2.This reverse osmosis system requires under-sink electricity. Main power cable 90", faucet's power cable 59". 3.Check if the reverse osmosis system uses the same socket with garbage disposal or dishwasher, if the RO system doesn't work when plugged in, please prepare a separate socket. 4.Drilling 2 holes for installation. One for RO faucet (1") and the other for drain pipe connection. 5.Placing this RO system after a salt-based water softener may affect the taste (reduction rate 90%).
NSF 58&372 certified The RO system is certified against NSF 58 for TDS reduction and NSF 372 certified for lead free material.The TDS removal rate is certified to be up to 91.9%, and the hexavalent chromium reduction rate is certified to be up to 96.9%.
Integrated water way design With the integrated water way design, the reverse osmosis system has no hidden danger of water leakage and is very safe, which gives you a peace-of-mind water purification experience with details.
400 GPD &1:1 pure to drain The highly efficient pure water flow of 400 GPD allows you to fill a cup of water in just 12 seconds; 1:1 pure to drain means that dispensing 1 cup of pure water produces only 1 cup of wastewater.

Questions and Anwsers

Can I use this reverse osmosis system on well water?

We do not recommend using well water as a source for our RO systems.
The reasons are as follows:
1. Large particles.
Compared to municipal tap water, the well water is rich in large particles, which will clog the filters easily, and shorten their life 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 a very complicated composition, 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.

Can the reverse osmosis system be connected to the refrigerator so the ice is filtered as well?

1. Generally speaking, yes, The RO system can be connected to your refrigerator.
After completing the registration online, you could choose the accessory kit, which will help you connect the RO to your refrigerator/ice maker.
Since different refrigerator/ice maker has a various requirement of water pressure, it's not possible for our RO system to provide them all. Connection under mismatched circumstances may result in many problems, including but not limited: slow ice making, frequent start-stop issues, etc.
Therefore, it's NOT recommended to connect the RO system to your refrigerator/ice maker.
2. To determine if the RO's outlet pressure is enough to be connected, you may need to acquire the refrigerator's pressure requirement first, which can be found in its user manual.
For your reference:
RO's outlet pressure: ca. 35 psi

What is the minimum water pressure to operate the Waterdrop RO system?

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

How to install Waterdrop reverse osmosis system?

Waterdrop RO systems are designed for DIY installation. You can install the system in 30 minutes. Simply refer to the instruction manual and instructional videos, or contact us by email, phone, or live chat.

When to change reverse osmosis filters?

G3: The CF filter has a 6-month lifetime; the CB filter has a 1-year lifetime; the RO filter has a 2-year lifetime. Waterdrop G3 Reverse Osmosis System has a smart faucet and filters life indicators that will remind you to replace the filter.

Does the G3 RO system need the eletricity to run?

Yes, the Waterdrop RO system needs electricity.

Is the RO unit certified by the water quality association (wqa) as a RO unit (NSF/ANSI F58)? where can I find the certification?

We are working with NSF and will get listed early in 2020.

How many gallons of "wastewater" is put out for each gallon of filtered water?

The drain ratio is 1:1. That means for each gallon of filtered water, the system will put out 1 gallon of wastewater.

Can I use our own faucet?

Truly sorry, the brushed nickel faucet is the only option available now.
You could use your own RO faucet with our product, but not a normal faucet for tap water.
There are a few things you may need to know before purchasing one:
Firstly, our faucet is equipped with a filter life indicator, which allows you to monitor the filters' life easily. If you decide not to use our original faucet, this function will not be in effect.
Secondly, your RO faucet should be able to connect with the outlet tubing of the system, which has a diameter of 1/4".
In addition, it should have a "Quick-Connect Fitting", please click here.
OR, it should come with a set of accessory parts, which allows you to connect the faucet with the bare end of our outlet tubing. Please click here to see the example for your reference.
If the faucet does not meet one of these requirements, you will need to acquire a corresponding adapter, in order to complete the connection with the machine.

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

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

What does Pure to Drain Rate mean?

The 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.
