evaluate As water testing turns into extra delicate and laws extra stringent, individuals are looking out to make sure they’re ingesting contaminant-free water. The Waterdrop G3P800 is a water filter that makes use of reverse osmosis and UV to deal with as much as 800 gallons per day. I’ve one to evaluate. Learn on to see what I believe!

What is that this?

The Waterdrop G3P800 Reverse Osmosis Tankless Water Filter is a excessive capability, excessive circulate, under-sink water filtration system designed to take away contaminants from municipal ingesting water. The system is computerized to dispense water from the chilly faucet connection and purify the water on demand by filtering it via a pre-sediment and carbon block filter, a reverse osmosis membrane filter, an activated carbon sharpening filter and a UV sterilizer. The filters are put in in an under-sink housing that hides the interior piping connections between the filters and likewise comprises the system electronics, native operation show, and booster pump. Water is allotted via a faucet that has a neighborhood show of filter well being and complete dissolved solids (TDS) on the outlet of the system.

Design and Options


The Waterdrop G3P800 Reverse Osmosis Tankless Water Filter is available in a big brown field that measures roughly 22″x25″x9″. There’s a image of the unit on the perimeters of the field. Every little thing inside is neatly packed in Styrofoam kind.

set up

Word that the field would not embrace every little thing you may want to put in the water filter. you’ll or might have

  • variable pace drill
  • utility knife or scissors
  • 1/2″ drill bit for drainpipe and 1″ bit for faucet gap
  • adjustable wrench and or pliers
  • flashlight
  • towel
  • screwdriver

Word that the situation the place it’s put in will need to have an accessible electrical receptacle and that the cupboard have to be not less than 20″ deep, 18″ excessive, and roughly 9″ extensive. Additionally acknowledge that the entrance of the unit have to be accessible to take away and change filters, the most important of that are 15″ tall. It’s endorsed that the unit be put in free-standing in order that vibration won’t be transferred to the counter whereas the unit is in operation. Requires entry to a 1″ drain pipe within the set up location so as to use the drain saddle.

Moreover, when the Waterdrop G3P800 reverse osmosis tankless water filter is working usually it can mechanically waste about 25% of the water put into it. This sounds excessive however industrial RO techniques can reject much more (>40%) water and this doesn’t embrace water that could possibly be used for backwashing filters and sanitizing the carbon mattress. The Waterdrop G3P800 will mechanically wash the filter within the waste line to keep up sanitary situations and maintain the filter working effectively for so long as potential. If you’re contemplating utilizing water in a restricted provide (for instance an RV) then this is probably not probably the most applicable method and normal filtration could also be a extra applicable method.

The set up steps are fairly straight ahead.
1. The directions begin with the plumbing however it could be helpful to verify the place every little thing goes first and to see how the system will match collectively.
2. A feedwater adapter is put in above the chilly water provide shut-off valve.

The adapter is 1/2″ and comes with bushings to adapt to the three/8″ provide. I’ve a decreasing valve put in in my kitchen so I used the provided bushing.

3. RO faucet is put in. My sink already had a cleaning soap dispenser so I eliminated it and used the opening for the tap.

The outlet is barely bigger than 1″ however it’s smaller than the bottom of the tap so it really works effectively. In case your counter would not have a gap, Waterdrop recommends that you simply first watch a YouTube video on your explicit scenario (granite, quartz, stainless, ceramic, and many others.). The lamp is hanging beneath the tap line.

4. The groove saddle is put in. The directions do not explicitly state this however the saddle ought to go between the drain of the sink and the plug on the base of the P lure (the U-bend a part of the sink).

I solely had 1″ of line popping out of my disposal so I put the road there. It’s in vertical place so there is no such thing as a chance of backup.

5. Set up tubing, electrical connections, and energy to the system in a way that enables for subsequent inspection of the system tubing. Tubing will be lower to size if wanted.

6. Put the system in final place. Verify for leaks.

7. Set up Filters. Verify for leaks.

8. Energy on the system

There are a couple of different choices out there with the Waterdrop G3P800 Reverse Osmosis Tankless Water Filter. Whether it is getting used with a fridge or different equipment, Waterdrop sells a small stress tank that may enhance the stress supply of water to the RO faucet and fridge. In case you want the style of mineral water, or need to be certain the water comprises sufficient minerals, a remineralization filter can also be out there for buy. Word that this filter can be utilized simply earlier than the faucet at any water supply to supply mineral content material.


On start-up, the system will mechanically flush the idle line for five minutes. The flushing has this good graphic on the system housing and RO faucet that appears like a waterfall.

After 5 minutes of flush, the RO faucet must be opened and water ought to circulate from the faucet cumulatively for half-hour. Throughout this time the water will not be potable (the water high quality could also be worse than the inlet water high quality because the membranes are flushed with particles). After cumulative half-hour of circulate via the faucet, the TDS degree will likely be displayed and the system is now totally operational.

The show on the entrance of the system housing and on the RO faucet each present the TDS measurement. TDS measurement is predicated on the conductivity of water with some conversion elements inserted. On the whole, TDS, or extra particularly conductivity, is an efficient measure to find out whether or not an RO is working successfully. A correctly operated RO system will typically scale back conductive ions within the water and since conductive ions are often smaller than different contaminants focused, dangerous contaminants are eliminated as effectively. Word that water will not be deionized and remains to be protected to drink even whether it is handed via an RO membrane.

UV lamp operation is indicated by a brilliant ring across the UV system. The UV expertise is LED based mostly however I believe it’s a separate blue LED slightly than a leak from a lightweight lure. LED UV expertise has longer life and decrease energy consumption than mercury vapor expertise lamps. UV lamps are a good way to be completely positive that there are not any microorganisms within the water and the Waterdrop G3P800 is likely one of the few techniques that features this expertise.

The deal with of the RO faucet can management the circulate of water to some extent however I often open all of it the best way to let the water circulate as shortly as potential. The utmost circulate charge is roughly one glass of water each 6 seconds. This equates to 900 GPD however the system has obligatory flush and filter substitute which limits the utmost every day capability to 800 GPD.

The tap and system housing have reminders when it is time to change the filter. The filter icon on the system housing and RO faucet will change shade to yellow when there are 15 days or 40 gallons remaining, and the icon will change to crimson when the system is depleted. The system housing will beep twice when delivering water from the yellow icon and can beep repeatedly when delivering water from the crimson icon. Each day use of about 70 cups a day will devour the filter capability earlier than it occasions out on every of their makes use of. At this charge, the filter indicator will flip yellow about 9 days earlier than it expires.

When it comes time to alter the filters on the Waterdrop G3P800 Reverse Osmosis Tankless Water Filter, the method is fast and simple. Filters are the sort that’s put in in most fridges. They’re pushed into the unit after which secured with a half flip of the filter. There’s a catchbasin contained in the unit with an integral leak detection circuit if a filter, sensor or booster pump is leaking. Urgent the system housing indicator for a changed filter for 7 seconds resets the filter utilization counter for the changed filter.

If the system will not be used for greater than per week, it is strongly recommended that the RO faucet be opened, the chilly water provide be turned off, and the filter eliminated and saved within the fridge.


My group has onerous, low-quality faucet water. After putting in the Waterdrop G3P800, I can actually inform the distinction between faucet water and RO water from Waterdrop. I believe it is higher than some bottled water I’ve tried. I’ve observed that my every day water consumption has elevated considerably with the fixed availability of top quality water.

I’ve an inexpensive TDS meter that I purchased from Amazon. The meter exhibits a discount of TDS by about 90% even when the values ​​differ from these displayed on the housing or on the faucet.

The water is on the identical temperature as our residence’s chilly provide or perhaps a bit of hotter. The under-sink location of the residence is adjoining to the dishwasher, disposal, and PVC drainpipe. All of these things are doubtlessly warmth producing and the lowered circulate charge of chilly water via the system might lead to a slight rise in temperature.

The booster pump makes a low drone sound when working. It isn’t loud, nevertheless it’s noticeable.

what i like

  • Excessive circulate charge for RO system
  • straightforward to put in
  • informative faucet
  • Full with UV Sterilization System

what would i alter

The Waterdrop G3P800 Reverse Osmosis Tankless Water Filter has a excessive upfront price, however bottled water will be expensive too. A store-brand water bottle will be as little as $0.97 per gallon, so the price of bottled water and this method is roughly the identical for the primary 800 gallons (6060 bottles). On common the system prices $165 per yr in filter upkeep, or the price of about 1300 bottles. So if the system is used to its potential, in a median yr the system will solely price about 25% of the price of utilizing bottled water. Not solely does this method get monetary savings and plastic, however everybody ought to have good ingesting water on the flip of a faucet.
