Things You'll Need
A faucet's bonnet nut, sometimes referred to as a collar, is used to hold the faucet's stem into place. Over time, the components within the faucet corrode, crack and otherwise wear out. This typically results in a faucet that leaks, thereby exposing the surrounding area to severe water damage, particularly if left unattended. A damaged faucet must be removed to repair or replace the faucet. To remove the faucet, it is first necessary to remove the faucet's bonnet nut.
Turn off the water supply. If the faucet is for a sink, the two water valves underneath the sink can be used to turn the water supply off. The valves are typically oval or circular in shape. To turn the water supply off at the valves, turn each valve in a clockwise direction. If the faucet is for a shower or bathtub, the water will need to be turned off at the main water supply valve, which is typically located next to the water meter.
Remove the faucet handle's cover plate. The cover plate is a circular plastic piece located in the center of the handle. Use a flathead screwdriver to pry the cover plate away from the handle.
Remove the faucet handle's retaining screw. The retaining screw is located directly in the center of the handle, as is revealed once the cover plate is removed. Remove the retaining screw with a Phillips-head screwdriver.
Remove the faucet's handle by pulling it away from the faucet.
Remove the faucet's bonnet nut. The bonnet nut fits over the faucet valve and holds the valve into place. To remove the bonnet nut, turn it in a counterclockwise direction with a wrench until the nut is free from the threads on the valve, then lift the nut up and over the valve to complete the removal process.
