33,000 Grain Water Softener Features

Rated a Consumer Best Buy

For performance and value by a leading consumer magazine.

Demand Initiated Regeneration

Uses up to 25% less salt and water than previous Whirlpool® models by monitoring your water usage and only regenerating when necessary. Older timer-based models regenerate on a set cycle regardless of how much water you’ve used; which can result in unnecessary water and salt consumption.

Salt Saving, 6th Sense® Technology

Creates significant savings in salt and water usage by automatically calculating the salt required to clean its media bed and using only what is necessary. (Competitive models typically use a ‘fixed’ amount of salt to regenerate the media tank regardless of how much water has passed through the system.)

High Hardness Removal

Removes a maximum of 105 gpg of hardness.

Iron Removal

Triggers an additional backwash cycle to rid itself and your water supply of excess non-ferrous (clear water) iron. Ferrous iron removal up to 9ppm.

Low Salt Light

Indicates the softener is working efficiently and flashes when the softener is getting low on salt, allowing you a few days to refill the salt tank.

Water Flow Indicator

Indicates when water is flowing through the system and may reveal potential leaks in your home’s plumbing.

High Flow Valve

Delivers great water flow with minimal pressure drop to your shower and appliances. Connects to plumbing up to 1” in diameter. (Connections out of the softener are 1” male pipe threads)

Do-It-Yourself Installation Kit

Comes with detailed instructions and everything to hook up to 1” NPT plumbing, including a bypass valve.  You will need the necessary connectors and enough tubing to connect from the water softener to your existing plumbing, access to 110V electrical outlet, and drain.  See installation manual for details. Don’t want to install yourself?
