GE has been manufacturing household appliances for over 100 years. Among the large selection of products they manufacture are water softening systems and their GXSH40V model is one of the best water softeners in the market.

It’s a very effective system that comes with innovative features like advanced SmartSoft Technology to provide optimum performance.

GE has a line of other water softening systems that offer different grain options and they include; GXSF30V, GXSH45V, GXSHC40N, and GXMH31H. Below is our detailed analysis of the GE GXSH40V 40,000 grains water softener.

Softening Capability

The GE water softener GXSH40V 40,000 grain unit softens your water the old-fashion way which happens to be the most effective way. Since this is a salt-based softener, it employs the ion exchange process to trap the minerals responsible for water hardness.

The unit is powerful enough to handle a high level of hard water up to 125 GPG. The 125 GPG means exceptionally hard water including that of a private well, so you don’t need to worry about it not being able to handle your level of water hardness.

On top of preventing limescale buildup, it also removes up to 8ppm of iron per gallon including colloidal iron, iron bacteria, and red-water iron and the same applies to GE water softener GXSH45V unit. Both models also feature a sediment filter that removes larger sediments from water to prolong the lifespan of the standard mesh resin filter.

This heavy-duty GE water softener is ideal for homes that source water with high hardness levels and chlorine content below 2ppm. However, to filter out chlorine taste and odor you may require an advanced unit like the GE GXMH31H model.

Capacity and SmartSoft Regenerating Technology

The GE GXSH40V is the second-largest GE water softener with a capacity of 40,000 grains per cycle which is enough to produce soft water for 1- 5 people households. Boasting a service flow rate of 9.5 at 15 psi drop, this unit softens your water with 1.107 cu. ft of resin.

If you are looking for a reliable large-capacity softener, the GE GXSH45V has the largest grain capacity of 45,100 which translates into 5,350 grains per pound of salt. However, GE also produces the GXSF30V which is the smallest unit in the group with a capacity of 30,400 grains.

Another great unit is the GE GXMH31H that comes with a grain capacity of 31,100 and unlike the GXSH40V model, it works both as a water softener and filter in one system.

The GE water softener GXSH40V unit works on a programmable operation and also features permanent setting memory. This means that it’s able to remember your ideal settings in case of a power outage.

What we like most about this unit is its SmartSoft Technology that can be used to adjust the system operations to the water use patterns in your household. The result is that you get a continuous supply of fresh soft water whenever you need it.

This GXSH40V unit is accompanied by an on-demand feed for salt regeneration. It also comes with a 230.0 lbs salt storage tank that is responsible for cleaning the resin when it reaches filtering capacity. Consequently, its large tank reduces the number of times you are required to refill the tank with salt.

To help manage the regeneration process, the unit features indicator lights that offer ‘days to empty’ feature, a low salt level alarm, and a status quo of the system. With the ‘days to empty’ feature, a display light will notify you how many numbers of days are remaining before the next salt refill. Normally the unit will regenerate about 3-6 days. This feature ensures the unit never runs out of salt.

Plus, it eliminates the stress of constantly checking the salt level and guesswork of trying to remember when the tank needs to be refilled. Its regeneration process takes approximately 2.5 hours and consumes about 37 gallons of water.

Furthermore, it’s designed to monitor your water usage and predict future demand to optimize the performance and soft water output. Compared to the older model, you can save up to 34% of water consumption and minimize salt usage with an efficiency of 5,090 grains per pound of salt.

The system is also equipped with a blending valve that allows you to customize the settings to different water needs. You can use soft or hard water for other things including watering your lawn or washing your car. In this way, you can save money and water since you only use soft water when needed.

The GE water softener GXSC40N 40,000 grains, on the other hand, is the most advanced of all the models. It features a built-in WIFI connect for notification, a remote water shutoff valve, and water usage tracking.

Note that there is a GE water softener for every need at different prices so you shouldn’t have trouble choosing just the right unit for you.

Installation and Maintenance

Thanks to the single-tank design and installation kit, setting up this unit is relatively easy if you are handy with tools. However, in some cases, there are fewer connections that call for a professional plumber.

Using a 1.5-inch connection pipe, place the system on the main water line, near a 24V electrical outlet, and remember to provide a drain. This unit is surprisingly energy efficient using 35% less energy at 60 Hz.

GE recommends you install the unit indoors or in a shelter. Considering that the damages due to direct silent or extreme freezing temperatures will not be covered by the warranty.

When it comes to programming simply set your water hardness level, the current time as well as the ideal time for regeneration, and not forgetting the current salt level. Once installed and configured, maintenance is quite easy, all you need to do is keep adding salt into the brine tank and follow the unit light indicators.

One of the few concerns of this unit is its salt-based nature meaning beneficial minerals will be removed. Plus, it is prone to have small technical issues that can be handled through technical support via multiple channels

GE backs this model with a one-year limited warranty on the entire system, a 10-year limited warranty on the resin tank, and a 3-year limited warranty for the electronic monitor.

Bottom line the GE water softener GXSH40V 40,000 grain is made to meet GE’s usual high standards and performance. We particularly like the energy-saving, water and salt reduction, and Smartsoft technology features.
