Abstract
A drain flusher device for dislodging an obstruction in a pipe. The drain flushing device has an elastomeric cylindrical body with an open neck end and nose portion having a thickened end wall. An elongated slit with a predetermined configuration and predetermined dimensions extends through the thickened forward end wall. A connector is fixed at the body neck end and is adapted for attachment to a pressurized fluid source, such as a garden hose.
Claims20
A drain flusher device for connection to a water pressure source of 50-90 p.s.i.g. for the expansive positioning in a conduit and for subsequently delivering a concentrated fluid spray from the front end of a flexible body, said drain flusher device further comprising:
- a. a unitary flexible cylindrical body of a specified diameter range with opposing ends and having a thickened end wall at one said end and a thickened open end wall at the opposite end, said flexible cylindrical body further having a diameter ranging from approximately 0.75 to approximately 3.25 inches and being for use in pipelines ranging from one to six inches in diameter.
- b. a flexible elongated slit through said thickened end wall, said flexible elongated slit having an effective, predetermined length and width which is independent upon said body diameter range and having a length of approximately 0.250 inches and a width of approximately 0.030 inches, and
- c. connector means fixed to said flexible body thickened open end wall and being adapted for attachment to the water pressure source, whereby upon the introduction of water pressure into said flusher device, said flexible body initially seats in the conduit before said concentrated fluid spray is delivered through said flexible elongated slit.
A flexible drain flusher device for connection to a water pressure source of 50-90 p.s.i.g. comprising:
- a. a unitary flexible cylindrical body having a specified diameter, a side wall and opposing ends, one said end being open and said opposing end having a thickened end wall, said thickened end wall further having a hemispherical configuration,
- b. an elongated slit through said thickened wall end, said elongated slit having a width of approximately 0.030 inches and a length of approximately 0.250 inches, and
- c. connector means attached to said body open end and being adapted for attachment to the water pressure source.
A flexible drain flusher device for expansive positioning in a conduit and for delivering a concentrated spray from a single opening in the front end of a flexible body and being constructed and arranged for operation with a water source having a pressure of 50-90 p.s.i.g. comprising:
- a. a unitary flexible cylindrical body of a specified diameter range and having a thickened end wall and an opposing open end, said body further having a specified side wall thickness and said thickened end wall having a thickness that is approximately 250-325 percent of said side wall thickness,
- b. A single elongated slit through said body thickened end wall, said elongated slit having a length of approximately 0.250 inches and a width of approximately 0.030 inches, and
- c. connector means fixed to said flexible body open end and being adapted for attachment to the pressurized water source.
