Abstract: A hydraulic plumber's friend has a cylindrical body, a lid, a compression assembly, a tapered end cap and a nozzle assembly. The cylindrical body has an open bottom and holds water to be injected into a clogged pipe. The compression assembly has a drive shaft and a piston mounted slidably in the cylindrical body. The tapered end cap is mounted on the open bottom of the cylindrical body and has a transverse partition, a tapered body and a spout. The nozzle assembly has a valve having a cylindrical disk mounted slidably in the spout and having a closed top, an open bottom, a cylindrical sidewall and multiple charging holes, a valve stem and a spring. When the charging holes are uncovered, water flows. The nozzle is mounted on the cylindrical disk and seals and directs water into an opening in a clogged pipe.

Abstract: A snake includes a handle, a flexible cable, multiple brushes with various sizes and a crank. The handle has a proximal end, a distal end and a ring with an eye on the distal end. The flexible cable is made of glass fiber and has a rear end attached to the proximal end of the handle, a front end and a connector attached to the front end of the flexible cable. A brush shaft has a rear end attached to the connector, a front end and a head attached to the front end of the brush shaft. The brushes each have a shank that can detachably attach to the head of the brush shaft. The crank is L-shaped and has a longitudinal arm, a transverse arm with a free end to be inserted through the ring and a cap with an aperture attached to the transverse arm of the crank.
