Rheem Preferred Water Softener: Is It a Worthy Investment?

After going through the detailed review of the Rheem preferred water softener series you might be wondering if they are good enough. First thing first, before getting products like these it’s necessary to evaluate what is it you actually want and what are your priorities.

Rheem Preferred Water Softener

Rheem water softeners are a good choice, because:

  • They offer multiple variants for different households;
  • These systems have a high GPG;
  • They are more affordable than others available in the market;
  • Minimal maintenance is required for these systems.

Perks Of Rheem’s Preferred Water Softener System

Rheem offers numerous benefits to its users. Let’s see what they have to offer:

1. Hardness-Free Water

Rheem water softeners can efficiently reduce the hard minerals in the water. The ion exchange methods used in these systems can significantly remove calcium and magnesium ions and replace them with sodium ions.

Rheem water softeners can efficiently reduce the hard minerals in the water

If your water contains a high content of iron, Rheem is the best choice available in the market:

  • They can efficiently clean up to 11 PPM of iron;
  • These water-softening systems are capable of removing hardness up to 140 GPG and provide you with spot and scale-free water.

2. Save Money

Rheem water softening systems are affordable solutions for hard water. With time, hard water can cause damage to your home appliances like water heaters and cooling systems.

The built-in learning technology in their water softeners calculates salt and water consumption and optimizes itself accordingly. Furthermore, spot-free clothes and reduced soap scum also contribute to saving you money.

3. Eco Friendly

Traditional water softeners use salt to remove hardness from water and the salt waste is then flushed down. This salt waste is harmful to plants as it affects soil quality and also has an impact on the environment.

Eco Friendly

On the other hand, Rheem water softeners use potassium chloride instead of sodium chloride which is environment-friendly and bio-degradable. By using Rheem you can enjoy soft water as well as contribute to a healthier planet.

Drawbacks of Rheem Water Softeners

Now that we have covered the positives of Rheem water systems, let’s take a look at the limitations of their systems, so you can make an informed decision.

Drawbacks of Rheem Water Softeners

1. The Upgrades Fail To Make a Mark

Rheem does not offer many variations when it comes to softeners. The only major difference in their softeners is the variable softening capacity and the only preferred platinum water softener comes with built-in Wi-Fi. Except for that, they don’t offer any extra features.

2. Lacks Salt-Free Alternatives

Rheem exclusively offers only salt-based water softeners which sets it behind its competitors. Some other brands offer both salt-based and salt-free alternatives which appeal to a wide range of customers.

3. Questionable Durability

The tanks of these Rheem systems are made of plastic which definitely raises the question of their durability. Other competitors offer fiberglass that is more durable than plastic casing. So while installing Rheem one must be extra careful to prevent any damage to the tank.

4. Warranty

Rheem offers up to a 10-year warranty which is a good thing. However, its warranty extension policy is not appreciated by many customers. If you want to extend your warranty, you have to buy their patented cleaner separately.

Rheem Water Softener Prices

Rheem’s competitive pricing offers an effective solution for dealing with hard water and achieving a good flow rate, making it an attractive choice for consumers:

Rheem Water Softener Prices
  • Portable water softeners typically range from $200 to $800, depending on factors like features and grain capacity.
  • Standard-sized water softeners, on the other hand, generally start at $800 and can go up to $3000.
  • Rheem water softeners fall within the same price range as portable options, starting at approximately $400 and reaching up to $600.

Rheem Customer Service And Guarantees
