Water softener systems are a significant investment. That can make picking the right system quite stressful. With so many systems to choose from, it’s easy to make the wrong choice and get stuck with a large, expensive water softener that takes up half of your basement.

That’s where ABCwaters comes in. Their water softening system combines a high flow fate with a space saving design that you can easily tuck into a corner. The system is also efficient, saving you money on salt. It’s also easy to install, with detailed instructions that come in the package. If you have any issues, you can even schedule a Face time call with tech support.

ABCwaters Built Fleck 5600sxt 48,000 Black WATER SOFTENER


  • 48,000 grain high capacity 
  • Eco-Frindly
  • WQA Certified
  • 12 Gallons Per Minute flow rate 
  • Black color

The system is a big investment. But it more than justifies the cost with its great flow rate, excellent durability, and quick installation kit. The system also has great durability, so it should give you years of performance.

Key Features

The ABCwaters system is designed to save space while still delivering enough water for a household of 2-5 people. The system features a 48,000 grain capacity tank. The tank also comes preloaded with resin, so you won’t have to fill it for the first water cycle.

The Fleck 5600SXT digital valve makes it easy to control the system, with push buttons that adjust flow and let you control water regeneration. The tank uses a cross linked resin that extends the life of the system. If you properly maintain the system, it should give you excellent performance for years.

The whole system weighs 133 pounds. While this may sound heavy, it’s on the light end when it comes to a water softener system. The system is also quite compact, making it easy to install in tight basement corners. If you need a fairly discrete water softener, this system is an excellent option.

Although it would be a stretch to say the ABCwaters system is stylish, it’s about as appealing as a water softener can get. The tanks have a smooth black exterior that doesn’t stand out too much.

The system can deliver a maximum flow of 12 gallons per minute. This should be enough to easily provide water for a household of 2-5 people. If you need enough water for an apartment building, this isn’t your unit. But if you have a medium sized household with a few kids, it’s an excellent option.
