The Flexx-HD is a heavy-duty, whole-home water softener built for reliability and efficiency. Its ceramic rotary disc valve and upflow brining design use up to 30% less salt than conventional downflow softeners — while delivering consistently soft water to every tap. Backed by a 7-year warranty on the valve and electronics, plus a lifetime warranty on the tanks.
Get a Free QuoteIf you've got crusty faucets, stiff laundry, or a water heater working overtime, hard water is the culprit. The Flexx-HD removes the calcium and magnesium causing the damage — using a proven upflow brining process that's more efficient than competing downflow softeners. It runs on just 24 volts (less than $2/year in electricity) and delivers noticeably better water to every room in your house.
The Flexx-HD's upflow brining design pushes water up through the resin bed, using only the salt it needs for each regeneration cycle. The result: up to 30% less salt than conventional downflow softeners, without sacrificing a grain of softening performance.
Ion exchange replaces the calcium and magnesium in your water with sodium — eliminating the minerals that cause scale, spots, and dry skin throughout your entire home.
Scale builds up silently inside your water heater, dishwasher, and washing machine — reducing efficiency and shortening their lifespan. A softener stops the buildup before it starts, so your appliances run better and break down less often.
Cloudy glasses, streaky dishes, and chalky faucets are all hard water's calling card. Soft water eliminates the mineral residue — so your dishwasher actually gets things clean and your bathroom fixtures stay shiny.
Hard water prevents soap from rinsing fully, leaving a film on your skin and hair. Soft water lathers better, rinses cleaner, and leaves your skin hydrated and your hair noticeably softer — while using less soap and shampoo.
With peak flow rates up to 20 GPM (depending on model), the Flexx-HD delivers uninterrupted soft water even when your whole family is running showers, laundry, and the dishwasher at the same time. The built-in bypass valve also lets you easily shut off or bypass the system whenever you need to.
Unlike conventional softeners that push water down through the resin, the Flexx-HD's upflow design moves water upward — using only the media needed for your actual hardness level. Combined with the ceramic rotary disc valve (time-tested and incredibly durable), you get a system that wastes less and lasts longer.
7-year warranty on the valve and electronics, lifetime warranty on the tanks. This system is built to last.
Uses less than $2/year in electricity. The 100-240V/50/60Hz transformer powers a 12V system — efficient and safe.
Easily shut off or bypass the system for maintenance, travel, or outdoor watering — no extra plumbing needed.
Sits straight on unlevel floors — no shims, no wobble. The brine tank holds approximately 180 lbs of salt.

No subcontractors, no surprises. Our local team manages the entire process so you can focus on enjoying your new water.
A local technician tests your water at your kitchen sink and shows you the results in real time — including your exact hardness level.
Based on your results, household size, and water usage, we recommend the right system and give you a transparent, all-in price — no hidden fees.
Our trained installers handle the full setup — plumbing, programming, and cleanup — typically in a single visit. You'll have soft water by dinner.
Salt-based softeners physically remove calcium and magnesium from your water through ion exchange — they actually make the water soft. Salt-free conditioners don't remove the minerals; they change their structure so they're less likely to form scale. Salt-based systems are more effective for high hardness levels, while salt-free options work well for moderate hardness and homes that want a maintenance-free approach.

| Prevents Scale Buildup | Yes | Yes |
| Adds Sodium | No | Yes |
| Maintenance Required | Low | Medium |
| Electricity Needed | No | Yes |
| Suitable for Septic Use | Yes | It depends |
