What you'll notice

  • Water flowing around cartridge instead of through it
  • poor water clarity even after cleaning
  • calcium-hardened pleats

Likely causes

  • Age (3-7 year lifespan depending on usage)
  • high pH or alkalinity causing calcium lock
  • aggressive pressure washing damaging fabric

How to keep it from coming back

  • Use chemical soak (TSP solution) at least once yearly
  • avoid high-pressure washing
  • maintain pH below 7.8
