If you’ve done some research on reverse osmosis water filters or have one at your home, you already know some of the weak points.
The most familiar of those is the product water to the reject water ratio. Some cheap RO purifiers would take 9 gallons of tap water to serve you only 1 gallon of purified water.
So, those waste a lot of water. As a result, many people nowadays look for a RO water filter that has a better waste and product water ratio.
In this article, we’ll be introducing you with a RO purifier that is currently the most efficient in utilizing tap water. The name of the product is the Waterdrop WD-G3 RO purifier.
We’ll be covering all the aspects of the filter- why it is so efficient, how you can install it, how much maintenance it requires, and so on. So, stay tuned.

How many stages are inside the Waterdrop WD-G3 water filter?
The Waterdrop WD-G3 Reverse osmosis water filter comes with seven stages of filtration combining three different types.
The first stage is the carbon block filter. It consists of blocks of activated carbon that will reduce the organic wastes from the water.
The supply water consists of pollutants like odor, Chlorine, Chloramine, and other organic and inorganic particles. The Carbon block filter gets rid of those.
Then, the water will enter the sediment filter. If the tap water carries any clay, sand, or pieces of debris, the sediment filter will remove those.
After that, water will go into the RO membrane. It will remove most of the dissolved solids from your drinking water.
So, you see, the composite filtration technology gives you pure and fresh water, reducing 99% of the contaminants and 94% TDS.

Why does the Waterdrop WD-G3 water purifier have no tank?
The Waterdrop RO purifier comes with an internal booster pump, which increases the flow rate inside the device. As purification happens fast, it doesn’t need a tank to store water.
What we see in most conventional RO purifiers is the presence of the tank. The tank is vital as filtering through the RO membrane takes time.
Therefore, the purifier stores pure water in the tank. And, as soon as you open the faucet, water comes out of the tank.
The booster pump of the WD-G3 filter ensures that water passes through the RO membrane fast. Due to the high pressure, it can serve you pure water without storing it beforehand.
The good thing about not having a tank is that it gives you more space. Also, as water will get out directly, there can be no further pollution from the tank.

How much water does the Waterdrop WD-G3 waste?
The Waterdrop WD-G3 RO water filter has a drain to output pure water ratio of 1:1. It means it will only waste 1 gallon of water to produce you 1 gallon of pure water.
The RO purifiers are notorious for wasting a lot of tap water. Most reverse osmosis systems would waste 6-7 glasses of water to give you only one glass of pure water.
So, you see, the product can significantly save you a lot of your tap water costs. With the booster pump, it will provide you a glass of water within only 12 seconds.
Why does the Waterdrop WD-G3 water filter use electricity?
The internal booster pump of this model of Waterdrop RO purifiers requires electricity to boost your incoming water pressure.
You may have already observed most of the conventional RO purifiers don’t need any electricity. They only use the inline tap water pressure to purify the water.
As a result, purification takes a lot of time. Moreover, if the input water pressure is low, the flow rate at the faucet will not be enough to pour you a glass of water.
But, none of this would happen in the Waterdrop WD-G3 purifier. If the water pressure is low, the pump will produce enough pressure head, so you get water in a few seconds.
In addition to all these, the product has a built-in TDS sensor to check your water quality. Also, you will find a filter life indicator. All these consist of electronic circuits.

Installation manual
How to install the Waterdrop WD-G3 RO water filter
So, by now, you already have some basic knowledge about the product and what it offers. Let’s go and see how you can install it.
To install the product, you will need the following tools as well.
- Utility knife
- Screw Driver
- Drill
- Adjustable wrench
Now, let’s see how to install the Waterdrop WD-G3 RO purifier.
Drilling a hole on your countertop
- First, you need to drill a hole in your countertop. It will work as the pathway to house the RO faucet.
- Choose a suitable place for the hole. Then, start at low speed and apply downward pressure with the drill.
- Make sure the drill remains straight throughout the process. The hole should have a diameter of 1-3/8'.
Installing the feedwater adaptor
- Now, shut off the water supply and turn on the kitchen faucet to let the remaining water go out.
- Then, disconnect the cold water supply pipe. Now, in that place, connect the feedwater adaptor and tighten it with the wrench.
- Finally, connect the cold water supply pipe to the feedwater adaptor.
Installing the RO faucet
- Now, you need to install the RO faucet into the hole. Start by inserting the faucet body into the hole.
- Then, properly place the gasket, nuts, power cord, and other accessories into the hole.
- Now, tighten all the joints as much as possible. After that, complete the connection of the fittings into the faucet body.
Installing the drain saddle
- Now, it is time to install the drain saddle for the RO reject water. First, create a 1/4" hole in the drain pipe.
- Make sure your drill doesn't reach the opposite side. Next, insert the tubing into the hole.
- Then, finalize the connection by positioning the screws and nuts appropriately.
Placing the RO system housing
- Next, you should place the RO system housing. Most people like to install it in a compartment under the sink.
- In that case, you need to make sure there is a power supply nearby. Then, create an opening so that the plug can easily reach it.
- Also, make sure the power plugs and others remain ample distance away if any water leaks from your supply line.
Connecting the tubes
- Now comes one other crucial part. It is time to connect the tubings properly.
- Unlock the input water port, and identify the tubing attached to the feedwater adaptor.
- Then, insert the other end of the tubing into the input port of the housing and lock the clip.
- Next, find out the tube connected to the RO faucet. Insert the other end into the filtered water port of the housing.
- Finally, it is time to connect the wastewater tubing. Locate the tubing, connect its remaining end to the wastewater port, and lock the clip.
Installing the filters
- After all this, it is time to insert the filters. Begin by removing the wrapping and coverings.
- Then, insert the filters in their respective housings. Now, twist the filter in the clockwise direction and make sure it fits.
- Follow these for all the three filters in the package.
Connecting the power cord and starting the system
- Finally, you need to connect the power cord into the housing and connect the input end to the power supply.
- Now, turn on the cold water supply. The system will keep flushing for 5 minutes. Then, turn on the RO faucet and let it run for 30 minutes.
- By now, all the indicators will start working, and you're good to go.

Maintenance
How often should replace the cartridges of the Waterdrop WD-G3 RO filter?
Now, let’s talk about the maintenance of your Waterdrop WD-G3 Water purifier.
Like all the RO purifiers, you will need to change the cartridges from time to time. That’s because the filters get jammed after working for a certain period.
For example, the first activated carbon filter will perform well for one year at a stretch. After that, it will lose some functionalities.
As a result, the TDS level might go up, and the filter might not be able to get rid of all the pollutants.
Similarly, the pre-sediment filter and reverse osmosis membrane can last for six months and two years, respectively.
You see, the maintenance schedule can be hectic to remember. Don’t worry. There are indicators to remind you when it’s time to change the filters.
Initially, you can take a look at the indicator on the faucet. It will change color when the time comes to change any of the three filters.
Then, you should take a look at the individual filter life indicator to identify which one is running out.
