Abstract: A priming-water conduit from a sink water faucet unit to a floor drain p-trap is located between the faucet valve and the faucet water-outlet. The faucet valve controls water flow into said conduit, and, therefore, into said p-trap, without any other valve or control system. The priming-water conduit may be attached, and in fluid communication with, various structures of the faucet that are downstream of the faucet valve(s), such as: the mixing chamber of a mixing faucet; the water line from the mixing chamber to the faucet outlet/nozzle; or any water-containing structure that is downstream of the faucet valve. Each time the faucet is turned on, by means of the manual faucet valve, a portion of the water passing from the valve to the mixing chamber and/or by other routes to the faucet outlet/nozzle, will flow into the priming-water conduit and to the p-trap.

Abstract: A combination pressure test cap for riser pipe and protective sleeve for protecting the riser pipe as it extends through a concrete slab, the test cap and the protective sleeve releasably connected together through use of a breakable connection.

Abstract: A system and device for installing and mounting conduit upon a surface such as a roof. The system made up of at least one support block having a base and an upper portion, a support rail and a variety of attachments for holding conduit to the rail. Each of the various blocks in the system configured to nest when oriented in a first direction to stack in an elevated position having a greater height when oriented in a second direction. These pieces are configured to work together to provide a mounting system with significant advantages over other devices that exist in the prior art.
