Why We Recommend the Fleck 5600SXT 48,000 Grain Water Softener

Most residential water softeners install in the basement near the main water line entry point. The Fleck 5600SXT 48K is the most popular DIY basement install for good reason: it ships pre-loaded with resin (no messy resin filling), the 10x54 tank fits comfortably in most utility closets, and the plumbing connections are straightforward 1-inch NPT fittings. A competent DIYer completes the install in 1-2 hours with basic plumbing tools. You need a floor drain nearby for the regeneration discharge and a standard electrical outlet for the valve timer.

Frequently Asked Questions

Where should I install a water softener in my basement?

Install your water softener as close to the main water line entry point as possible, after the water meter but before any branch lines. You need a floor drain within 10-15 feet for the regeneration discharge hose, a standard electrical outlet within 6 feet for the valve controller, and enough clearance to add salt (the brine tank lid needs to open fully). Most basements have all of these near the water heater area. Keep the softener above the flood line if your basement is prone to water.
