Rated 4.3 out of 5 by 75 reviewers.
Rated 4.0 out of 5.0 by First rate water softener Bought this unit about 8 months ago, Wasn't hard to install, and haven't had any problems. Since initial service, it's only used about 40 lbs of salt for a two person household. It's way more efficient than my old water softener that worked on a timer. One caution, and the only reason I'm not giving it 5 stars, is it does restrict the total water flow. When there's two or more water users in service, you see a big drop off in water pressure. If your household is more than 2 - 3 people, you should get a larger unit that has a higher flow capacity. February 11, 2012
Rated 3.0 out of 5.0 by Great Product - Weak Warranty Support The performance of the product (when it is working) is excellent. Unfortunately at 3 months, the the primary valve failed, burning out the motor and control board. The service technician is excellent, even working on Saturdays, but GE corporate support is weak. The product is still down after 7 weeks, with the technician struggling to get proper repair parts from GE. I am normally very happy with GE products, but after this experience, I would not buy a GE product for critical application like a water heater. March 8, 2011
Rated 5.0 out of 5.0 by What a relief!!! After many years with another brand water softener treating our well water, we finally have the product we always wanted. My water is wonderful and can be used just as it comes from the faucet. The laundry and dishes are cleaner than ever before. Our salt use is minimal compared to what we needed before with the previous unit. We are so satisfied that we recommend it to anyone who needs this product. Ordering online was easy, timely, money-saving, and convenient. Delivery was a matter of very little time and right to the basement. Installation was done within 2 hours. What a great experience! Another GE product that does what it promises. Thank you GE and Home Depot January 29, 2013
Rated 4.0 out of 5.0 by So far so good. I had a Whirlpool softener but during some home renovations, I had to disconnect the pipes and move the unit. During the process some water sprayed onto the electronics and fried the circut board. You live and learn. This GE softener system's electronics board is actually somewhat protected by being encased in a separate compartment. Installation is easy. I have only had this unit for a month but it works and I am happy. The price point is right where is should be in my opinion. It's hard to give something like this rating. It either works or it doesn't. Does anyone ever need to see a list of options for a hammer? October 12, 2011
Rated 4.0 out of 5.0 by Works well for us This unit has been installed for over a month in our house now and is working great. We realized the change in water hardness immediately in our showers, dishwasher, laundry, etc. A lot of the reviews regarding this product state that after 5 years the product failed and they had to purchase a new one. I am a firm believer that you get what you pay for and if you want something that is gonna last 10+ years go out and buy a rainsoft system for $8K. If this product last me 2-3yrs and I have to replace it, I would feel like I got my money out of the purchase and would have no problem purchasing another one. January 24, 2012
Rated 5.0 out of 5.0 by GE 40,000-Grain Water Softener System Despite some reviews I did buy this water softener and did install myself. I did already have a main water line loop put in by the home builder so pipes were already for the system. It was very easy to install and set up. I was concerned about the plastic in & out pipes on the unit but it doesn’t leak at all, and all of the store brand system I seen all were plastic as well. it has been running a week now and everything is going good. I would buy it again. May 31, 2011
Rated 5.0 out of 5.0 by excellent I bought this water softner about 4 months ago and it has yet to regenerate. I still have soft water, but i live alone so I do not use much water. I would recommend this particular model over any other models or brand. Easy to install, but the only drawback is the bypass valve is flimzy/cheap. May 18, 2011
Rated 5.0 out of 5.0 by Great Water Softener So far this water softener has worked quite well. I had very hard well water and was replacing my hot water heater every year or less. I have only had it a few weeks but I can already tell that it is working since the bathtub has not been turning green like usual and I don't have streaks in my toilet bowl anymore. It was VERY easy to install also. It comes with hardware that fits regular 1" PVC but I have 3/4" CPVC pipes so I had to get an adapter for that which wasn't a big deal. Other than all I needed was a few elbow joints, a few extra feet of cpvc, and some pvc cement and it hooked right up to my cpvc pipes. Programming it was very easy also. The display is very simple and straight forward. My only problem was I did not realize I was going to need a place to drain 30-40 gallons of water every time it recharched. The only place I could install it was about 60ft. from my sump pump so be sure you have a drain nearby or you'll have to go buy a 100 ft. hose like I did to drain it somewhere else. Overall I would recommend this water softener. September 6, 2011
