GE Water Softeners
Read this first
GE lists both softeners we track as no longer manufactured. Retailers are selling remaining stock, still at $569 for the GXSH40V and $586 for the GXSH45V when we checked in August 2026, and both hold NSF/ANSI 44 certification. The units themselves are sound. The question worth thinking about is what happens in year eight when the control head needs a part.
What discontinued does and does not change
GE's product pages carry the no-longer-manufactured note on both the GXSH40V and the GXSH45V. Stock is still moving through retail, which is why the prices have barely shifted from where they sat when the models were current.
Most of a softener is not model-specific. The resin bed is a consumable that wears out on its own schedule, 10 to 15 years on municipal water and 5 to 10 on iron-bearing well water, and rebedding costs $200 to $400 on any unit regardless of the badge on the front. GE warrants the resin tank for ten years and tanks rarely fail before that.
The model-specific part is the control valve head and the electronics inside it. GE covers electronics for three years and parts and labor for one. A control valve job runs $300 to $600 installed, and on a discontinued model the risk is that the sensible repair path narrows to swapping the whole head rather than rebuilding it.
Our general rule holds here: a valve repair is worth doing under ten years and rarely worth doing past ten. Discontinuation tightens that window. It does not close it.
The 40,000-grain badge is a ceiling, not a rating
GE sells the GXSH40V as a 40,000-grain softener. That number is what the unit delivers when dosed with 15.1 pounds of salt, the highest setting it offers. The same manual rates it at 11,700 grains on a 2.3-pound dose.
The GXSH45V works the same way. Its 45,100-grain maximum needs 17 pounds of salt, and at the 2.6-pound setting the manual rates it 13,200 grains.
GE is not being unusual here. Every salt-based softener on this site is marketed at its maximum-dose figure. It matters because the efficient setting is the one you will actually run, so the honest comparison between two units is at a similar salt dose rather than at the number printed on the box.
Every GE unit we track

| GE GXSH45V | salt-based | 45,100 gr | 17 lbs | 9.5 GPM | NSF/ANSI 44, NSF/ANSI/CAN 372, WQA CSA B483.1 | 1 yr parts/labor, 3 yrs electronics, 10 yrs resin tank | $586 | Check price |

Specs read from manufacturer pages. Each unit's page lists its source and check date. “—” means not yet sourced, never guessed.
How the two models differ
The GXSH45V costs about $17 more and buys two things: roughly 5,000 grains of extra maximum capacity, and an iron rating of 10 ppm against 8 ppm. Both move 9.5 gallons per minute and share the same 47.6 by 14.4 by 22.4 inch cabinet, so neither is easier to fit into a tight utility space.
At a $17 gap the larger unit is the obvious pick when both are in stock. On well water the iron rating alone settles it, and there is no running-cost penalty for going bigger because dosing is metered on both.
Who should still buy one
A discontinued unit makes sense if the price reflects the risk and you are the kind of owner who replaces rather than repairs. At $569 and $586 these are priced like current budget cabinet units rather than like clearance, which is the weakest part of the case for them.
If you want the same class of unit without the parts question, Rheem's Preferred RHS32 is $489 at Home Depot and the Preferred Plus RHS42 is $589. Neither Rheem lists third-party certification, which both GE units do, so the trade runs in both directions.
Where to go from here
Brand matters less than size and type. Start with the capacity your household needs, then decide salt-based vs salt-free, and only then compare GE against the alternatives at that size in the full comparison chart.
Frequently Asked Questions
Is the GE GXSH40V discontinued?
Yes. GE lists both the GXSH40V and the GXSH45V as no longer manufactured. Retailers are selling through remaining stock, and both were still listed at $569 and $586 respectively when we checked in August 2026.
Should I buy a discontinued water softener?
It depends on how you handle repairs. Resin, tanks and brine components are generic and serviceable regardless of model status. The control valve head and its electronics are the model-specific parts, and those are what a discontinued model puts at risk after the 3-year electronics warranty ends. If the discount is real, the bet is reasonable. At full current-model pricing it is harder to justify.
How many grains does the GE GXSH45V actually deliver?
45,100 grains at its maximum 17-pound salt dose, and 13,200 grains at the efficient 2.6-pound setting. The 45,000 figure in the model name is the maximum, not what the unit produces on a normal cycle.
Is GE or Rheem better for a budget softener?
Rheem is cheaper and current. The Preferred RHS32 is $489 against the GE GXSH40V at $569. GE carries NSF/ANSI 44, NSF/ANSI/CAN 372 and WQA CSA B483.1 certification, and Rheem lists no third-party certification on its product pages. You are choosing between a verified capacity claim on a discontinued model and an unverified one on a current model.
