Why Choose a Rheem Water Softener?

Rheem offers four types of water softener systems, all requiring salt. Their systems vary mostly based on your household size.

Salt-Based Water Softeners

The most common type of water softeners, salt-based systems use ion exchange to replace hard minerals with sodium. Rheem’s salt-based models come with features such as automatic regeneration, customizable settings, and smart connectivity for ease of use.

Smart Technology

All Rheem water softeners utilize the company’s proprietary smart technology to learn your water usage patterns to provide on-demand soft water. This technology reduces water usage and optimizes salt consumption. In addition, each system has a low salt monitor and lights that flash to indicate certain alerts.

Cost Savings

Rheem boasts that their systems will pay for themselves through cost savings in two to three years given their cost-effective technology. In fact, the company estimates that its softeners help households to save up to $558 a year by saving up to 24% in water heater electricity costs by removing build-up, improving the efficiency of all water systems.

In addition, the softeners themselves only use an estimated $5 annually in electricity costs and $10 in annual water costs. On top of that, they use 40% less salt than competing systems.

Warranty

Rheem prides itself on its industry-leading, extendable warranty. The warranty is 1 year for parts and labor, 3 years for electronics and 10 years for tanks. You can extend the 1-year warranty up to five years when you regularly use the company’s branded water softener cleaner.
