Your Water Softener Causes Discolored Water: 5 Expert Tips

If your water softener causes discolored water, it could be due to ion exchange resin breakdown, iron fouling, or brine tank issues. Resin breakdown can release iron oxide, causing red/brown water; check for proper backwashing, salt levels, and consider resin replacement. Iron fouling clogs resin and needs chemical cleaning. Brine tank issues like salt mushing, bridging, or high iron levels in salt can also discolor water. Check water hardness, iron levels, and pH for optimal softener performance.

Now, in this detailed guide we have shared hands-on, nitty gritty troubleshooting tips on resolving discolouration issues in a practical manner.

How Do I Confirm The Water Softener Is Causing Discoloration?

Before tearing apart your entire plumbing system, verifying your softener is the cause prevents unnecessary work elsewhere. Here is a foolproof confirmation process:

Step 1: Visually Inspect The Conditioning Tank

  • Use a flashlight to peer inside softener’s brine tank – locate either where salt is housed or jet nozzle for salty water injection during regeneration.
  • Check walls and submerged surfaces for any debris, film, or reddish-brown rust lining the inside.
  • Severe rust lining that coats tank walls signals corrosion – a key cause of downstream water discolouration.

Tools needed:

  • Flashlight
  • Cloth/sponge for wiping tank

Step 2: Analyze Which Water Taps Show Staining

  • Note down which kitchen/bathroom taps or toilets exhibit discolouration versus cleaner fixtures.
  • Discoloration originating due to softener corrosion tends to appear strongest nearest the system before fading over pipe distance.
  • If sinks closest downstream from your softener entry point show staining while upstairs/far away ones do not, softener is likely the issue.

Tools needed:

  • Drinking glasses
  • Note pad for tap appearance logs

Step 3: Capture Water Samples In Clear Containers

  • Collect discolored water samples in transparent glasses – from stained sinks close-by the softener versus far away taps.
  • Visually compare samples from both sources. If sinks nearest your softener show deeper yellow/reddish-brown hue versus lighter tint in distant glasses, it points to the softening system being the root cause.

Tools/Materials:

  • Clear glasses, containers
  • Water from taps at varying locations

Once you’ve confirmed corrosion inside your unit as the driver of water quality issues, targeted steps to fix the root cause will eliminate discolouration for good.

Why Is My Water Conditioner Causing Brown Or Reddish Water?

Now that you’ve pinned down your softener as the culrpit, understanding the technical factors driving corrosion inside it is crucial to outline solutions:

Rust Accumulation Inside Brine Tank

The high salt content sodium chloride brine solution is highly corrosive for metallic surfaces like the resin tank interior lining. Left unaddressed, rust flakes build-up over time and eventually enter your water supply during the ion exchange softening process as red or brown particulate.

  • Root cause: Brine solution corrosion
  • Solution:
    Scrubbing tank atleast yearly prevents significant buildup that then manifests as colored water.

Gradual Degradation of Resin Beads

Water softener resin beads have a finite lifespan ranging 8-10 years typically, after which their ion exchange capacity drops while hardness mineral seepage rises. As older resins near end of lifecycle, colour leaching from their breakdown also occurs. Beads at age 10+ years often crumble significantly, releasing fragments into water supply.

  • Root cause: Old, exhausted resin bed
  • Solution:
    Catching deteriorating capacity early is key. Schedule complete resin replacements after 8-10 years.

Infrequent Regeneration Cycling

Regeneration depends on a strong brine solution for resin cleaning. Too little salt causes incomplete flushing while ineffective backwashing fails to cleanse fully. The remaining residue, when exposed to subsequent hard water enters supply. Running more frequent regeneration cycles paired with proper salting levels maximizes efficiency.

  • Root cause: Poor / incomplete regeneration
  • Solution:
    Top off salt more often while setting device to regenerate more frequently (eg. twice a week instead of once).

High Ferrous Iron In Incoming Untreated Water

Well water or public supply entering your home can contain naturally elevated dissolved ferrous iron levels – which rapidly fouls softener resin beds through oxidation and scaling, risking tainted effluent if capacity drops excessively.

  • Root cause: Fouled resin bed
  • Solutions:
    Use resin bed cleaners paired with more frequent regenerations. If issues persist, replace media or prefilter incoming supply to remove iron at source.

What Hands-On Steps Fix Discolored Water From The Softener?

With the root cause pinpointed from our troubleshooting above, targeted diy repairs can now resolve staining issues for good.

Step-By-Step Guide To Fixing Rust In Brine Tank

Supplies needed:

  • Salt enriched with rust removal chemicals like sodium hydrosulfite or citric acid (1 bag)
  • Non-abrasive cleaning brush/sponge
  • Chlorine disinfecting solution (bleach or hydrogen peroxide based)
  • Large bucket (5 gallon capacity)
  • Salt (2 bags)

Steps:

  1. Turn off water inlet valve to softener and open nearest faucet to depressurize lines
  2. Drain brine tank fully using rear located drain valve.
  3. Open tank lid then scrub interior walls vigorously with disinfectant solution using brush/sponge to displace rust particles from surface and submerged areas. Take care not to damage plastic liner.
  4. Once loosened rust is removed, refill tank with salt containing additives like sodium hydrosulfite at inner fabricator recommended dosage to prevent re-formation of reddish-brown iron oxide deposits.
  5. Run 2-3 rapid manual regeneration cycles allowing solution to flow through resin bed to purge fully.
  6. Draw test samples from nearest sinks until flowing water runs completely clear sans discolouration. Means tank flush is working.
  7. Check salt level monthly and top off appropriately to prevent recurring issues.

Step-By-Step Guide To Fixing Old Resin Beds

Supplies needed:

  • Resin bed cleaner (1 liter) – formulated with citric acid or NaClO2
  • Backwash hose with floor drain/bucket
  • Replacement resin bed (food grade)
  • Gravel bed for tank base

Steps:

  1. With salt tank still empty, start rapid manual regeneration
  2. Catch outflow from cycle in bucket/drain hose to measure colouration. Repeat backwashes until effluent runs clear. Doing so cleans resin bed in place avoiding replacement need.
  3. For severely degraded resin, remove existing media then refill softener tank with new beads compatible with your model. Ensure proper gravel base before re-loading.
  4. Treat new resin bed additionally with specialized KleenRite cleaner to maximize lifespan and efficiency given incoming water quality per manufacturer. instructions.
  5. Run multiple manual cycles post-media replacement to settle bed followed by effluent testing to confirm colour is eliminated for good.
