STEP 1: Gather Your Tools & Parts

STEP 2: Remove 4 Bolts

Locate and remove the 4 bolts on the outside edge of the aerator. You will need the Phillips head screwdriver for this.

STEP 3: Remove Top Cover

Remove the green top cover from the base. This will reveal the insides of the aerator.

NOTE: The first time this is done it can be quite difficult. If needed use a Flathead screwdriver to pry the cover off.

STEP 4: Remove Filter

Remove the rectangular cloth like filter that is wrapped around the unit.

NOTE: This can be very snug be careful not to rip the filter.

STEP 5: Detach Rubber L-Tubes From Mounts.

Next detach the L shaped rubber tubes from the mounts. You only need to detach the top part (as pictured below). You do not need to detach it from the base.
