Water softener replacement costs
There are a lot of factors that determine the cost of your water softener replacement. The type, your water's hardness and labor costs all affect the price.
Water softener repair costs by type
The type of water softener you need depends on how much water your home uses and the number of minerals in your water. Magnetic water softeners tend to be the cheapest pick, but you may need something with a little more filtration, like a reverse osmosis or water distiller system. Larger homes often need a dual-tank system to keep up with the water demands of more sinks and toilets.
| Type of water softener | Cost |
|---|---|
| Magnetic | $200-$600 |
| Single-tank ion exchange | $500-$1,700 |
| Salt-free | $800-$4,000 |
| Double-tank ion exchange | $1,000-$5,000 |
| Water distiller | $1,200-$4,000 |
| Reverse osmosis (point-of-use) | $1,500-$1,800 |
| Reverse osmosis (whole home) | $4,000-$11,000 |
The price of a new water softener can vary greatly depending on your water hardness. During testing, water hardness is measured as 1 grain (64.8 milligrams) of calcium carbonate dissolved in 1 gallon of water (gpg). Hard water is water with a gpg of 7.5 or higher. Anything lower is considered soft water.
With gpg measurements, the higher the capacity level, the more you can expect to pay. Generally, a home with one to four people will need a system rated at around 30,000 gpg, while homes with five to six people will need a system that’s around 40,000 gpg.
| Water softener GPG capacity level | Cost |
|---|---|
| 24,000 | $300-$500 |
| 32,000 | $400-$1,000 |
| 48,000 | $600-$1,200 |
| 64,000 | $800-$1,500 |
| 80,000 | $1,500-$1,800 |
| 96,000 | $1,700-$2,500 |
If your system was doing its job well before it stopped working, go ahead and get the same size and type as your old system.
Water softener installation costs
If you choose to hire someone to install your water softener, that will add to the overall cost. The cost of hiring a plumber will vary depending on who you hire and where you live.
Can you DIY a water softener replacement?
You can easily replace your water softener in around an hour since all the plumbing is already in place. The process just involves screwing a few pipes together.
When should a water softener be replaced?
The biggest sign your water softener needs replaced is when your water isn’t “soft” anymore. You’ll start noticing things like water spots on drinking glasses, your soap not lathering when you wash your hands or limescale (white, flaky bits) showing up on your faucets. These are all signs of hard water.
Does your home warranty cover water softener replacement?
Home warranties cover the repair and replacement of appliances and systems around your home, including water softeners. If your water softener stops working, you may only need to pay a deductible to replace it. This can save you hundreds to thousands of dollars, especially since your plan probably covers installation.
