Can Water Softener Cause Pressure Loss in Shower:7 Quick Fix

Yes, water softeners can cause pressure loss in showers, typically due to sediment buildup or clogged filters. For instance, a 1/16-inch sediment layer can reduce flow by up to 50%. Key factors include resin tank size, regeneration cycle frequency, and water hardness level. Regular maintenance, such as filter cleaning/replacement and checking for resin bed blockages, is crucial to mitigate pressure loss.

Challenges, Troubleshooting, and Solutions for Water Softener-Related Pressure Loss in Shower

ChallengeTroubleshooting StepSolution
Sediment Buildup in Resin TankInspect for sediment presence by opening the tank or using a sediment detection kit.Flush the resin tank with a cleaner designed for your system. Increase backwash frequency to prevent future buildup.
Clogged FilterCheck pre-filter and inline filters for clogging.Replace clogged filters. Consider upgrading to a higher capacity filter if clogging is frequent.
Incorrectly Sized Water SoftenerCompare water usage and peak flow demand with the softener’s specifications.Upgrade to a correctly sized unit that matches household water demand to ensure adequate flow and pressure.
Resin Beads DegradationLook for signs of resin bead fragments in the softened water.Replace the resin bed. Use high-quality resin beads suitable for your water hardness and system specifications.
Blockage in Brine Line or Injector SystemPerform a visual and manual check for obstructions in the brine line and injector system.Clean or replace parts as necessary. Regular maintenance checks can prevent these blockages.
Malfunctioning Control ValveObserve for irregular cycle patterns or failure to regenerate.Consult the manufacturer’s manual for specific valve troubleshooting. Replacement or professional repair might be required for complex issues.

Why Does My Water Softener Reduce Shower Pressure?

There are a few reasons why your newly installed water softener can cause a drop in water pressure:

1. Clogged Resin Beads

  • Softener tanks contain tiny resin beads which trap hardness minerals
  • Over time, dirt, sand and sediment in water can clog up resin beads
  • This reduces the free space for water to flow through the mineral tank
  • Lower flow rate directly translates to lower water pressure

2. Partially Stuck Valves

  • The electronic control head has tiny valves to regulate backwash & regeneration
  • Old water deposits can prevent valves from fully opening or closing
  • This again hinders water flow through the softener, lowering pressure

3. Exhausted Resin Bed

  • If resin beads are not recharged properly, they remain coated with minerals
  • This leaves less area for water contact and ion exchange
  • Can occur if brine concentration or regeneration frequency is inadequate
  • Again means restricted flow and loss of water pressure

4. Leaking Seals

  • The seal around the riser tube and other fittings can become loose or damaged over time
  • This allows water to bypass the resin bed instead of passing through it
  • Gives the illusion of pressure loss without any flow restriction

How to Fix Water Softener Pressure Problems?

Step 1: Check the Inlet Valve & Water Meter

  • Use a dual scale pressure gauge capable of reading 0-100 psi water pressure
  • Attach the pressure gauge directly to the inlet water line via a hose bib to get accurate inlet readings
  • Readings below 50 psi with all household taps closed indicate issues with the main water line sizing or flow
  • Check if the mainline inlet valve leading to the water softener is fully open
  • Inspect inlet water meter for correct sizing – should be 0.75 inches diameter minimum pipe

Step 2: Clean/Check Resin Beads

  • Remove the mineral tank head assembly to access the resin bed
  • Use a resin bed degreaser solution or 1 tbsp bleach per 5 gallons of water for cleaning
  • Stir the resin beads gently with a PVC pipe section to lift dirt and sediments
  • Scoop out any broken beads or foreign particles from the mineral tank
  • Rinse resin bed thoroughly ensuring water runs clear when done

Step 3: Inspect Control Head & Valves

  • Open control head cover and inspect electronic display & wiring
  • Check battery voltage – should be no less than 6.2V for proper valve operation
  • Examine piston, seals and spacer stack assembly for wear or binding
  • Remove piston assembly and wipe seals clean removing any debris
  • Lubricate seal surface and rotor bushing points with food grade silicone oil

Step 4: Monitor Regeneration Cycle

  • Initiate a manual regeneration cycle and observe flow to troubleshoot problems
  • Check brine draw flow rate during backwash cycle
    • Should fill mineral tank completely in 10-15 mins
    • If brine draw is slow, inspect brine line and eductor assemblies
  • Similarly, brine refill should typically take 15-20 mins
    • Uses same line flow – if slow, indicates line blockage
  • Repeat regeneration 2-3 times to clean resin and free valves

Step 5: Adjust Salt Dosage & Regen Frequency

  • For medium hard water of 5-10 gpg, use 8-12 lbs of salt per regeneration
  • Increase salt dosage by 2-3 lbs if resin bed is not fully regenerated
  • Buy 99.9% pure evaporated pellet or solar salt for water softeners
  • Adjust brine tank refill time to ensure sufficient salt saturation

Step 6: Identify & Fix Leaks

  • Remove mineral tank head assembly and inspect internal O-ring seals
  • Ensure distributor tube seals securely into control valve o-ring
  • Apply plumbers pipe thread seal tape on external pipe connections
  • Tighten fittings to a quarter turn past hand tight using adjustable wrenches
  • Wipe surfaces clean & check for leak points during a manual regeneration
