It is recommended that you change the washers in your Clean Rain Advanced or Clean Rain Ultra downspout filter and diverter every 12 - 24 months. This is the set of 46 fiber washers that you would use to replace the existing washers in your Clean Rain diverter.
Replacement is a snap! Simply remove the bottom portion of the Clean Rain diverter (shown to the right) and remove the small nut holding the washer assembly together. Remove the small black housing and washers and replace. Re-tighten the nut and re-attach the bottom section and you are ready to go!
