Question 1

How is this different than the wd-g3-w?

Accepted Answer

Dear Customer,

Thank you very much for reaching out to us.
Both G2 and G3 are smart under sink water filtration systems using reverse osmosis technology. Designed for easy installation, both of the models are tankless with the integrated waterway and composite filters. The water flow for G2 and G3 are both 400 GPD, 0.28GPM with the 1:1 drain water ratio.
The G2 model is an economical option compared with G3 in terms of water filtration performance. Here’s some major difference between the two models, which I will elaborate for you from several aspects.
●Filters: G2 has two composite filters with 5-stage filtration; G3 contains three composite filters with 7-stage filtration.
●Filter life:
○G2: one year CF filter, two years RO filter
○G3: six months CF filter, one year CB filter, two years RO filter
●RO faucet:
○G2: no need to plug in the faucet.
○G3: Cable smart faucet with filter life indicator, the faucet has a light loop to indicate filter life in different colors.
●Front panel:
○G2: Filter life indicating display panel.
○G3: Filter life indicating with a real-time TDS reading LED display panel.
●Certificates:
○G2: FCC Approved
○G3: FCC Approved, UL Listed, NSF 58 & NSF 372 Certified, Reddot Design Award
To enhance the user experience, compared with G2, G3 has added some additional features and designs:
●Automatic flushing: the system will be automatically flushing under the following circumstances
○Flush for accumulative working time over 2 hours
○Flush for No Working within 24 hours (Holiday Mode)
○Flush for power restore
●System self-protection
○E01: Water shortage
○E02: Inside water leakage
●Anti-vibration pad: The G3 unit adds rubber anti-vibration pads to increase stability and reduce noises.
In a word, both the G2 and G3 are great filtration systems that can achieve the same filtration performance to effectively removes more than 1,000 contaminants in water.

Question 2

I plan to add an inline remineralizer between the unit and faucet dispenser. Is the tubing 1/4 or 3/8 inches?

Accepted Answer

Hello,

Thanks for your interest in our Waterdrop WD-G2-B Reverse Osmosis System.
In theory, you can add an inline remineralize filter between the RO system and the faucet dispenser. But if you do that, there may be some risks that will have a negative impact on the RO system. 
Please note the following points when adding an inline remineralize filter:
1. The size of RO filtered water tubing is 1/4", please confirm whether the size of the inline remineralize filter's will match.
2. With the increase of the pH, the filter material will generate more gas which is easy to cause the pressure inside the tube rises, and the following situation arises.
a. if the housing material of the remineralize filter you use is not solid enough, it is easy to explode with the high pressure. 
b. if the gas can not discharge in time, the pressure inside the tube becomes higher, the pressure may reversely entry into the RO system, which causes serious damage to the RO system and affects the normal use of the system. 
c. when you open the faucet, it can not dispense water immediately. Because it has to bleed out the gas inside the tube first.
If you have any questions, please feel free to give us a call between the hours of 8:00 AM-5: 00 PM (PST), Monday through Friday at 1-888-352-3558. We will try our best to help you out. Thank you very much.

Question 4

Would this system filter sodium out of my well water?

Accepted Answer

Hi,
Thanks for your interest in our Waterdrop G2 RO System.
Yes, as a benefit of the RO membrane (filtration accuracy: 0.0001μm), this product is able to remove the sodium from the source water.

However, compared to municipal tap water, the well water is rich of large particles, which will clog the CF & RO filter easily, and shorten their lifetime significantly.

Therefore, it's recommended to add a pre-filteration system before the RO system, in order to prolong the filters' lifetime.

In addition, the well water may not be able to provide the feed water pressure that the RO system needs. Furthermore, the water pressure will be even lower after the pre-filtration systems.

So it's recommended to confirm that your feed water pressure meets the RO system's requirement, which is 14.5-87 psi.

The customer's satisfaction is always our top concern. If you have any questions, please feel free to give us a call at:
