The present disclosure relates to a device for preventing access to a conduit. The device comprises top and bottom compression plates and a compressible member between the compression plates. A bolt has a first end mounted to the bottom compression plate and a shaft passing through openings of the compressible member and of the top compression plate. The bolt has a head proximate its second end. The head of the bolt extends beyond a major diameter of the threaded shaft. At least a portion of the shaft is a threaded shaft. The head of the bolt prevents a nut mounted on the threaded shaft between the head and the top compression plate from being dismounted from the device. A fluid passage may extend in the compressible member between the top and bottom compression plates to allow a fluid to bypass the device.

A portable plant instrument freezing and bursting prevention device using a non-directional serial connector includes a main body portion, a plurality of heat wire portions, each of the plurality of heat wire portions comprising a male connector having a cylindrical shape, a heat wire having resistance, and a female connector having a cylindrical shape and having a hollow portion with both ends open, which are sequentially coupled to one another, and an end cap inserted into the female connector at an end of the plurality of heat wire portions to short-circuit the female connector, in which the male connector of one of the plurality of heat wire portions is inserted into the female connector of another one of the plurality of heat wire portions, and thus the plurality of heat wire portions are serially connected to one another.

A draining device for use with a fluid spout includes a main body including a stem portion defining a first aperture configured to fluidly couple with a pressure source. The main body may further define a base portion defining a second aperture configured to fluidly couple with a fluid spout of the fluid spout. The main body may further define an internal passage extending from the first aperture to the second aperture. The main body may fluidly couple the pressure source and the fluid spout through the passage.

An anti-freezing apparatus comprises: a main block including an accommodation space and a water inlet at one side thereof to communicate with the accommodation space; a temperature sensitive member provided in the accommodation space and having one end for opening and closing the water inlet, the length of the temperature sensitive member variable due to expansion or contraction according to changes in temperature; an elastic member installed between the temperature sensitive member and the main block; a connecting rod connected to the other end of the temperature sensitive member; a locking part having opposite ends locked in a locking protrusion formed in the accommodation space and having a through-hole through which water passes; and an adjustment part coupled to the tip end of the connecting rod and rotatably screw-coupled to the locking part. The elastic member applies an elastic force to the temperature sensitive member to close the water inlet.

A temperature response valve is disclosed. The valve has a body with an outside surface and an outlet. The valve has a sleeve that partly engages the outside surface of the valve body to direct, via channels on an inner surface of the sleeve, water flowing out of the valve body outlet. The water is held into contact with part of the outer surface and expelled at a removed end of the sleeves where the channels open to the environment. The valve engages the threads on a threaded male member of an outside faucet.

A hose/conduit clearing apparatus has an electric blower, a check valve, and a faucet coupler; the faucet coupler having a first end for threading to a faucet, a second end for threading to a conduit, and a blower connecting port wherein the blower is coupled to the blower connecting port via the check valve. The electric blower is preferably powered by one or more batteries and is activated automatically when reaching a predetermined temperature (e.g., 34 degrees Fahrenheit) or by a user toggling a switch.
