If your aerator is running louder than usual call your Jet service technician to schedule a routine maintenance visit. This could be a sign of early wear on the aerator brackets, causing excessive vibration that will reduce the life of your aerator. A service technician can fix or replace these brackets and clean debris that may have unbalanced the aerator reducing the noise and ensuring a longer life cycle from your aerator. If your system is new and you find the noise level is unpleasant Jet supplies an Aerator Silencer option that can be purchased from your local Jet distributor.
