Customer Questions & Answers

i bought a gxsf40h last week run well question is it recharge every 2 days my hardness is 30 GPG and we,re only 2 people in the house is this normal?

first day i didn,t bypass the water for my garden hose now i do. have a dish washer also that i use maybe every 2 days. if i calculate the gallon of water used it will be 40000/30*.8 is this right? so il use 1066 gallons of water every 2 days?
Asked by: Anonymous
That sounds a bit high, try lowering the hardness level a couple of degrees slowly over the next couple of weeks. See if you can get it to twenty without noticing any softness level.

what is the warantee on for this model gxsf 40h

Asked by: Anonymous
I'm not the one to ask this! You should definitely ask the manufacturer. In fact, (as with any product warantee) you should read carefully the warantee details. That said, my unit is working fine after more than six months.

how long i change salt or product

Asked by: Anonymous
Depending on how hard your water is one factor. My machine is set to 20. 160 pounds of salt will last me several months. The factory level is 25. Harder water uses more salt.

40,000 Grain Water Softener System is rated 4.3 out of 5 by 76.
Rated 1 out of 5 by from Leaked all over the basement floor. We only had this model for three years. It is now leaking all over the floor from the body of the softner. Bought it at home depot. Not making this model anymore so I can not replace. Waste of money!

Rated 4 out of 5 by from 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.

Rated 3 out of 5 by from 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.

Rated 4 out of 5 by from 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?

Rated 4 out of 5 by from 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.

Rated 5 out of 5 by from 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

Rated 5 out of 5 by from 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.

Rated 5 out of 5 by from 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.
