Occasionally, the cartridge nut, also known as a bonnet nut, on a Jado faucet can wear out and cause the faucet to leak, requiring that the nut be removed. The plastic bonnet nut fits over the valve stem and requires a special bonnet nut wrench to remove the part from the faucet valve stem. The cartridge nut is accessed by removing the Jado faucet handle. This part can be removed in about a half hour with a few shop tools.
