ABSTRACT:
A plug assembly for a faucet includes a casing adapted for engagement with the faucet, a cylinder securely received in the casing and having an isolator having a tapered through hole defined through the isolator and slits to communicate with the outlets of the cylinder, a top ring supported by the cylinder to sandwich the isolator with the cylinder, wherein the top ring has a hole defined through a bottom face of the top ring. A control rod is slidably received in the tapered through hole of the isolator and the hole of the top ring. A push rod is securely connected to the control rod to sandwich a friction ring with the control rod. An adjusting device is provided to adjust deformation of the friction ring such that the engagement of the friction ring to the inner periphery of the tapered through hole is adjusted.
