Abstract: A water heater is restrained against movement, such as during an earthquake, by a restraining system. The restraining system includes a pair of adjustable straps, which accommodate water heaters of various sizes. One end of each strap is securely attached to a supporting surface, such as a wall. The other end of the straps contain a plurality of slots configured to receive a connector. A connector is positioned in a desired slot or slots in each strap such that when the straps are placed around the water heater, the connectors are positioned proximate to each other. An adjustable fastener such as a bolt is inserted through an aperture in each connector to adjustably fasten the connectors together. The adjustable connector allows fine adjustment of the tension of straps around the water heater.

Abstract: An anti-rotation pipe locating and support device comprises a support and insert assembly that precisely locates and supports plumbing pipes relative to the structure of a building and prevents rotational movement of the pipes relative to the support. The support includes a support that can be fastened to the building structure and has one or more support openings for receiving the pipes. Inserts are used to receive and grip the pipes to secure them within the support openings with or without additional fastening techniques. Each support opening has at least one small tab which forms a lock with a slot provided in the insert, or is shaped to cooperate with a non-circular opening in the support to restrain the insert. The lock prevents the insert and pipe from rotating inside the support opening. The support and insert assembly also prevents lateral, vertical, and axial movement of the pipe relative to the support by constraints provided between the support and the insert.

Abstract: A cleaning tool for preparing the surfaces of pipes and fittings for soldering, welding or gluing comprises a base and a pair of opposing prongs. The tool further includes a distal set of replaceable brushes for cleaning the inner surfaces of pipes or fittings and a proximal set of replaceable abrasive pads for cleaning the outer surfaces of pipes and fittings. The tool is configured to accommodate pipes and fittings of a variety of diameters.

Abstract: An apparatus for testing a network of plumbing pipes for leaks comprises a pair of housings and a slidable test plate. The test plate is interposed between the housings to block fluid flow through the housings when inspecting the pipe network for leaks. After testing is complete, the test plate is removed from the housings and the housings remain fixed as a permanent part of the pipe network.
