The Ultimate Guide to Water Softener Troubleshooting: 20 Tips & Tricks

If you never get to know your water softener, you won’t be able to tell what’s wrong with it–even when you know it’s not working right. Take it from our Master Tradesman.

Do you love the gritty taste of hard water? Do you delight in wearing stiff, crunchy clothing? How about the joys of a plumbing system clogged with limescale?

If you answered “heck no” to all three questions, congratulations: you’re in the right place! Learn to recognize and fix 20 common symptoms of a troubled water softener below.

Psst! This guide assumes you’re already monitoring your water softener’s salt level.

1. The water softener isn’t doing its job.

General, widespread signs of trouble might indicate that your water softener is…well, not actually softening your water at all.

What You May Notice:

– Scale buildup on fixtures and appliances.

– Difficulty lathering with soap and shampoo.
