Asked by JD March 4, 2021

Answers

Blinking red light means that 6 months have elapsed since the original installation or last filter change. Get a replacement input and output filter kit. In the kit is a new coin cell that goes into the faucet. Follow the instructions with the kit to change all the parts. Once you do that, the faucet will light blue again for a few seconds after using it. If you have only one or two people using the water, you may not need to change the filters twice a year. You can reset the faucet six month timer by taking the coin cell out for 30 seconds, then putting it back in.

GE R.O.Filtration System
It was easy to install and it puts out great tasting water.
by GeBur
Worthless
This is the 3rd time this worthless thing has leaked on me. To qualify myself I’m a licensed HVAC contractor and a longtime municipal wastewater professional, I’m pretty sure I can install push to connect fittings correctly. But they’re cheap and have failed 3 times now. The icing on the cake is it never worked well anyways. The tank pressure was set correctly and the flow rate was somewhere around 2 cups per minute. So for the 3rd time, reaching for a new trash bag that was wet, I knew exactly what it meant. Shutting off my kitchen water, emptying the cabinet, drying with a fan, dinner became ordering in and now it looks like I need to replace the cabinet.

Filtration System
[This review was collected as part of a promotion.] Received this unit a few days back and installed , first off installation is a breeze after I installed unit did what instruction said and 24 hours later had system set and ready to use I did have one small leak but that was due to me not cutting line straight recut and no leaks. I love it for my drinking water the only down side to me is my coffee does not have has much flavor when i use this .Over all very nice unit and easy to install and set up Thank you GE.

Easy to install.
Filter change not very easygoing. Water outgoing too small

too small
The water tank is half the size of my previous system. Its just not big enough for a family of 3 to use constantly. Installation wasnt too labor intensive. The water line that goes from the filters into the tank hooks to the top of the tank. It leaks! 2 different plumbers tried to fix it, in vain. Its going back!

CONS: Parts bag was missing from package box. GE Appliances Service telephone support was poor and not helpful. Required a return trip to the store. PROS: Home Depot is customer-friendly and helpful. Eventually, after resolving unnecessary hassles of installation, the unit works well and meets my expectations (although I fear the high costs of frequent 3 filter-cartridge replacements). Smart advice: As all good technicians know, be sure to verify that "all parts" are included and in good condition BEFORE starting any installation process. On 10 Sept 2019, I purchased a GE under sink Reverse Osmosis Water Filtration System, Model #GXRQ18NBN, from a local Home Depot store for $199.99. During my pre-installation preparations, I discovered that the new GE box package was MISSING a parts bag with several key items. That's an unexpected hassle. Worse yet, I called GE Appliances Service and Support telephone 800-626-2005 to request delivery of the missing parts bag - and their telephone reps abandoned me on "indefinite hold" three times with no resolution! They couldn't resolve this small problem. No help. Frustrated! Do you remember when a simple phone call could solve problems? Now it seems that every big company like GE cuts back on "customer support" telephone service and refers all customer problems to their user-unfriendly website. Sadly this is today's new normal. My only alternative was to put everything back into the box and return it to Home Depot for a refund. At the store a helpful Home Depot customer service rep brought forward a replacement package box with all parts included. An easy exchange and I was on my way home to perform the installation. The installation is not difficult for a DIY-er. Just use good technical sense and pay attention to details to assure no plumbing problems or leaks. Attached are 11 Sept 2019 photos of my kitchen sink installation of this new GE under sink Reverse Osmosis Water Filtration System, Model #GXRQ18NBN. - -

This UNDER SINK REVERSE OSMOSIS WATER FILTRATION SYSTEM is pretty good. My sink didn't have a hole port for the water dispenser but I wanted to try it out before completely installing it to make sure it worked and how the water tastes to see if I liked it or not. I actually do like it and am going to completely install it this weekend. Before I used water gallons and it was always a hassle for drinking water, but this will eliminate that and I would just have to change the filter every 3-6 months. I recommend this to people who want to eliminate the hassel of buying galloned water.

I was delayed in installation of this Item as it has water requirements that needed me to install a water softener filtration system before I could put this in. If you are not on a well system and are looking to remove city water contaminants then by all means don't hesitate. This is an easy item to install and it works great. Only problem we ran into, beyond the water softener, was the PH test kit wasn't very well explained and we were confused by the 24 hour purge requirement. All said and done. nice fresh water for coffee , Ice and drinking from a well where we couldn't bare the smell from. To Determine your requirements have your well tested as not all well water has "contaminants" in it that require additional filtering or softening for this unit to operate. The unit is made of plastic and steel. The pressure tank is compact and everything you need except tools are included in this kit. Yep the faucet comes with it also. Take note that this is a stand alone unit and is not a kitchen sink type faucet with hot and cold water it is strictly a drinking water filtering system.

I chose the Under the Sink Reverse Osmosis Water Filtration System because we live in the country and use the wells on the farm for our water, this system will help to insure that we are drinking good water. Upon unpacking the system my husband has decided that it is better to call a professional to install it as it seems to be more than he is comfortable doing. I have friends that have this very model and I know how happy they are with it. The instructions are very well written and easy to see.

The GE Reverse Osmosis Filtration System came with everything you need to install in a standard setting. I had to order a separate part to connect the drain connection from the RO membrane reject water, but everything else came with the system. I already had a drilled hole for the faucet, which would had been extra work. The color coded tubes made following the instructions simple. I needed a reverse osmosis filtration system in my kitchen and this is a nice compact unit that does not take the whole space under my sink. The 1 3/4 gal. tank storage is a good size and gives me enough filtered water for my needs. The faucet works fine too.
