Undersink System Filter Replacement Guide

Watch the tutorial above or follow the quick-reference steps below

💧 Estimated Time: 20 min 💧 Difficulty: Easy 💧 Tools Needed: None

Supplies Needed

  • Replacement filters
  • Towel
  • Bucket
  • Filter flushing kit (included)
  • Marker to date filters

Helpful Tips

  • Only disconnect elbow fittings from the filter ports. Leave the tubing attached to the elbows (unless you are replacing fittings).
  • Keep it simple. Instead of removing all of the filters at once, replace one filter at a time. This will allow you to easily keep track of filter orientation.
  • Install new filters with the arrows pointing in the same direction as the old filters • Fittings are color-coded (Orange = Inlet; Blue = Outlet)
  • You can leave the water on at the filter faucet throughout the filter changing and flushing process. You will only be turning water on and off at the shut-off valve where water enters the filtration system.
