Typical Water Softener Installations

Water softener installations vary in difficulty depending on whether you're installing a new softener or replacing an old one. Simply replacing an old water softener can be done in under an hour. On the other hand, a new installation may require some additional plumbing knowledge, but it can still be tackled in a few hours. You may need to cut some piping to align your new water softener to your water supply lines, so be sure to preview our list of what you'll need to ensure you're properly prepared for installation.

What You'll Need

Whirlpool water softeners come with everything needed to install and hook up your softener to a 1-inch NPT (National Pipe Thread). If your plumbing is smaller or larger than 1-inch, please review our list below to get the right tools and materials for your installation.

  • Two 1-inch NPT female connectors and enough tubing to connect the water softener to your existing plumbing. If you have copper, PVC, CPVC, steel or PEX plumbing they may require different materials and different tools for installation.
  • 12 feet of drain tubing is supplied. In the event that your drain is further than five feet away, you will need to purchase more half-inch tubing to reach your drain. A drain should not be more than 30 feet away from a softener. Also, a drain line should not be elevated more than eight feet above the floor.
  • The power cord (transformer) will need to be plugged into a 110V continuous live outlet. Each unit comes with a 10-foot power cord.
