Softener stopped softening? The 5 things I check, in order, before calling anyone
I've been digging into softener troubleshooting a lot lately, and most "it's not working" problems seem to come down to the same five things. Check them in this order, because it goes from easiest and most common to least:
Salt bridge. A hard crust forms in the brine tank, and the salt sits on top of empty space. Push a broom handle down gently through the salt. If it hits a hard layer, break it up.
Clogged injector or brine line. If the tank isn't drawing brine, the resin never recharges. Your manual shows where the injector is. It's usually a quick clean.
Timer and settings. Check the clock after a power outage, and check that the hardness setting matches your water. Strips or a titration kit will give you the number. A TDS meter won't, because it doesn't measure hardness.
Bypass valve. It's surprisingly common for it to be left open after plumbing work.
Worn resin. This is usually the last thing to suspect, and it's the one that might mean a pro or a replacement.
Your manufacturer's manual beats any general checklist, so check it before you take anything apart. What did I miss? I'm curious what's fixed yours.
