Customer Questions & Answers

Can you use potastium instead of salt, is there a advantage ?

Asked by: Anonymous
Hello Rick, Thank you for your inquioy ont eh GE 45,000 Grain Water Softener model # GNSH45E. Yes, for customers who are on a salt restricted diet, you can use potassium chloride as a substitute for softener salt. However, keep in mind that potassium chloride may be slightly more expensive than salt and the unit will regenerate more often as potassium chloride is not as efficient as salt. We would also recommend the consumer set the water hardness 20% higher if using potassium chloride instead of salt. Potassium chloride is not salt. Therefore, people on restricted diets can use potassium chloride in place of salt, also known as "sodium chloride". Check the salt level a few weeks after you install the softener and once a week after that. Refill it when the brine tank is 1/4 to 1/2 full and never allow it to run out of salt. I hope this helps.

Age and Recharging Media

I have this unit in a townhouse I just bought. It was set up for whole house (inside) use for 2 people and normal appliances. I believe it to be about 9-12 years old. Is there a way to tell its age? I've read the life expectancy is about 10 years. Is it intended that the unit then be thrown away or can the media beds be rebuilt like on other larger softeners? Is there any way to determine if it is still working and/or efficient other than a water hardness test? Thanks in advance

How do I choose the right model of water softener?

I followed instructions in a previous answer for sizing the water softener. I calculated 375 gallons used daily times 15 grains per gallon, which calculates to about 5625 when multiplied together. How does that relate to the 30,000-grain capacity or 40,000-grain capacity? Does that just mean that I would need to replace salt more often in a lower capacity model?

Hello Barbara, Thank you for your inquiry on the GE water softener. These figures may be used as a starting point. There is no harm in specifying a higher capacity softener. In the long run, a higher capacity softener may be more convenient. 1. Your water hardness, Grains per Gallon 2. Average gallons per day per person 3. Number of people in household: Multiply the number of people in the house by 75 to get the average number of gallons used per day by the house. For example, a house with two people in it would use 150 gallons per day (2 x 75 = 150). 4. Multiply step 2 by step 3 5. Multiply answer in step 4 by answer in step 1. (This gives the hardness that needs to be removed daily.) 6. Multiply the answer in step 5 by 3 to get the size of the softener needed. This is the minimum capacity estimate for a new water softener I would recommend to contact your local Home Depot store for further assistance. Have a good day! Donna with GE

Customer Reviews

45,000 Grain Water Softener-DISCONTINUED is rated 4.0 out of 5 by 5.
Rated 4 out of 5 by from Doing what it's supposed to do I have noticed some difference when showering. In the past soap would immediately wash off given the hardness of the water. Now there seems to be an almost residue-type of feeling, where the soap feels a little more silky on the skin. Too early to tell if there's any benefit from washing clothes or dishes, but so far I've been pleased. System is easy to use. Programmed to run overnight, and it's quiet (even though it's located in the basement I ran the system once during the day to understand how it works, and it's quiet). Still playing around with settings to see what's going to work best for family and I, but will figure things out over time. I have been told that this isn't a unit that can compare with higher-end softener systems, but again I think it's serves the purpose. I'm not sure if a lesser grain softener would perform as well, but wanted to make sure that we've got as much of a benefit as we could have possibly had, without going to a higher-end softener.

Rated 1 out of 5 by from Upset with product and warranty I bought this softener for my house and placed it in our well house. Worked great for a few months then suddenly the control board went out. Called GE about the warranty because we had it less then a year and they said the warranty was voided when we didn't install directly into our house! Everyone I know installs them in their well house and I have never heard of them having to be installed inside your house. Loved this product while it worked had great soft water. Wished they would make it clear that a well house is considered outside! [This review was collected as part of a promotion.]

Rated 5 out of 5 by from Easy to install and use. This softener replaces a GE softner that I have used for several years. This new softener has a larger capacity and is much easier to program than my old one. It is working exactly as it should.

Rated 5 out of 5 by from Excellent performance with great results I chose this GE softener based on the features and quality of my other GE appliances. It has delivered what I had expected from a GE appliance. Great clear soft water with minimal attendance. Adequate features and easy to understand and follow. Backed by a great GE service and support team. [This review was collected as part of a promotion.]
