Water Softener Guide, Care & Troubleshooting Guide
A neglected water softener is one of the most overlooked pieces of home maintenance in a rental home. If the salt runs low, clumps, or sits below the waterline, the unit stops softening water even though it looks like it’s running normally. Hard water then builds up in pipes, water heaters, and fixtures over time. Follow this guide to keep the unit working properly and avoid unnecessary service calls.
Best Practices: How to Maintain Your Softener
To keep your softener working correctly and your water quality consistent, follow these simple guidelines:
- Check Monthly: Look at the salt level in the brine tank at least once a month. Salt should always sit above the water line inside the tank.
- Keep It Half to Two-Thirds Full: Add salt when the tank drops below half full, and never fill it more than two-thirds full. Overfilling increases the risk of the salt clumping together.
- Use the Right Salt: Pellet salt is recommended over solar or rock salt. It has fewer impurities and leaves less residue in the tank, which means less maintenance overall.
- Break Up Clumps: If the salt looks like a hard crust rather than loose pellets, gently press down into it with a broom handle to break it apart.
The “Don’ts”: Common Softener Mistakes
Many softener problems come from a few avoidable habits. Avoid the following:
- Don’t Let It Run Empty: Letting the tank run out of salt for weeks at a time allows hard water to pass through untreated and defeats the purpose of the unit.
- Don’t Overfill: Filling the tank all the way to the top makes it harder for salt to dissolve evenly and raises the risk of bridging.
- Don’t Mix Salt Types: Stick to one type of salt. Mixing pellet, crystal, and block salt can speed up clumping.
- Don’t Ignore Standing Water: If water is visibly sitting above the salt after you’ve added new bags, the unit may not be cycling correctly. This is not a salt problem and should be reported.
Troubleshooting: If Your Water Feels Hard
If you’re noticing spots on dishes, film on fixtures, or soap that won’t lather, try these steps before submitting a request:
Step 1: Check the Salt Level
Open the brine tank lid and confirm salt is visible above the water line. If the tank is low, add salt and allow a few days for the next regeneration cycle to run.
Step 2: Check for Bridging
Press down into the salt with a broom handle or similar tool. If it doesn’t give, the salt has hardened into a crust and needs to be broken up so it can dissolve.
Step 3: Check the Bypass Valve
Most units have a bypass valve near the connection point. Confirm it’s set to the “in service” position and not accidentally switched to “bypass,” which sends water around the softener untreated.
Frequently Asked Questions
How much salt does my unit typically hold?
Most residential brine tanks hold between 150 and 250 lbs of salt, roughly 4 to 6 standard 40 lb bags. Fill to half or two-thirds full rather than topping off completely.
Why is there still water sitting above the salt after I added more?
This usually means the unit isn’t completing a regeneration cycle correctly, rather than a salt shortage. Submit a maintenance request so a technician can check the valve and cycle timing.
When to Submit a Maintenance Request
If you’ve checked the salt level, broken up any bridging, and confirmed the bypass valve is set correctly, but water still feels hard or the tank continues to hold standing water above the salt, please log a request through the Tenant Portal.
Note on Service Fees: Please be aware that if a technician is called out and the issue is found to be caused by low or empty salt levels that were not maintained, a service fee may be applied to your account.
