How to Clean and Repair a Sink Faucet Spray Nozel? When it’s time to clean or repair a sink faucet spray nozzle, be very careful since there is an array of small parts involved. Unscrew the aerator from the end of the spout with tape-wrapped pliers. Disassemble the parts inside the aerator body and set them aside in the correct order and orientation: a part reassembled upside down will keep the aerator from working.
Whatever its design, your aerator will contain a plastic or rubber washer, a disk perforated by tiny holes or a sawtooth edge, and one or more screens. A more complex model may also have a disposable adapter for internal and external spout threads, and air-intake holes in the outer shell.
Clean the screens with a small stiff brush; use the brush and a toothpick to clean out disk and intake holes. Replace badly worn or misshapen washers, and flush out all parts by holding them upside down in a full stream of water before reassembling the aerator.
On some models you can unscrew the tip of a spray nozzle by hand. More often it is secured by a Phillips screw and the screw may be concealed by a cover. Pop the cover out with a screwdriver of penknife, remove the retaining screw and disassemble the internal parts.
Clean or replace these parts as you would those of an aerator; before reassembling them, run water through the spray head at full force for a minute or two. Do not try to repair the mechanism inside the spray head. If defective, this sealed unit should be replaced by an identical model from the manufacturer.Premium kitchen and bathroom fixtures:
