विवरण

If you’re dealing with hard water — scale building up on faucets and showerheads, dishes spotted after washing, soap that just won’t lather right, or laundry feeling stiff and rough — this system is designed to help reduce those issues throughout your entire home or facility with a whole house approach.

The problem you’re facing

Hard water leaves a layer of mineral deposits everywhere it touches. You see it as a crusty ring inside your toilet tank, a cloudy film on your glass shower doors, white spots on dishes, and dull, stiff towels and clothes. Soap feels like it sits on your skin rather than washing away easily. Besides being a nuisance to clean, these minerals can build up inside your pipes and appliances.

Why it’s happening

Hard water is water loaded with calcium and magnesium minerals. When water evaporates or heats up, these minerals come out of solution and form solid deposits called scale. The simplest way to confirm hard water in your home is with a hardness test kit, which measures mineral levels in grains per gallon. If yours is over 7 grains per gallon, you’re dealing with hard water.

What it’s costing you to leave it

Scale buildup isn’t just unsightly. Over time, it shortens the lifespan of your water heater, dishwasher, and other appliances by making them work harder. You’ll use more soap and detergent to get anything clean, which adds to your household expenses. The mineral stains get tougher to remove the longer they sit, leading to more scrubbing and cleaning time.

How this system helps

This water softener works by swapping the hardness minerals in your water for sodium ions through a process called ion exchange. Water passes through resin beads inside the tank, which hold onto the calcium and magnesium and release sodium in their place. The result is water that acts softer around your home—soap lathers easier, spots reduce, and scale buildup slows down.

What this system can handle

The WSP 120 cu. ft. Whole House Water Softener is built on the Fleck 3900 control platform, known for durability and precision. It’s designed for larger homes or commercial settings where water use is high and water hardness is significant. This system can handle continuous water flow and regenerates (cleans its resin beads) efficiently to maintain soft water without interruption. It’s well suited for households or facilities to manage hard water issues throughout all plumbing fixtures, appliances, and laundry.

What you actually get

Included with this system is a pressure vessel (the mineral tank) covered by a lifetime warranty, giving you peace of mind about its durability. The control valve and electronics come with the manufacturer’s standard warranty. A bypass valve is included so you can isolate the softener for maintenance without shutting off water to your entire home. You’ll also receive 10 feet of discharge hose for the drain line, ready to connect.

Is this the right size for you?

This model is ideal if you have a large household, a commercial water demand, or particularly hard water that needs a higher capacity system. If your water use is smaller or your hardness levels are moderate, a smaller system might be a better match and more cost-effective. Our team can help confirm the right size after reviewing your water problem and usage.

Living with it

Maintenance mainly involves replenishing salt and occasional cleaning of the brine tank, which your plumber can guide you on. The Fleck 3900 system is reliable and built to keep working with only routine service. The bypass valve makes servicing straightforward and doesn’t interrupt your water supply.

What it won’t do

This water softener helps reduce hardness minerals but does not remove other contaminants such as bacteria, sediment, or chemical impurities. If you have issues like bad tastes, odors, or sediment, you’ll need additional treatment systems designed for those specific problems.
