ABSTRACT:
A self-actuating drip valve for attachment to a standard faucet for the prevention of freezing of exposed water pipes. An elongated housing includes means for securing one end of the housing about the open end of the faucet. A valve seat is provided within the housing so that it is substantially adjacent to the faucet when the device is in use. Substantially concentric extendible walls extend between the elongated housing and a base plate. A valve stem, terminating in a valve tip, is secured to the base plate and extends within the extendible walls. The base plate may be adjusted by threadable means for moving the valve relative to the valve seat.
