A three-way elbow for connection between a trap and a waste line is provided with a valved access ending in a plug. Removal of the plug allows attachment of a first end of a hose in its place. The second end of the hose is held above the water level of a sink by attachment to a board that fits over the sink. A snake inserted through the hose is directed by passageways in the elbow to the waste line. A container is mounted between a faucet for the sink and the second end of the hose so that disinfectant in the container can be carried into the hose. Brushes are mounted in the second end of the hose so as to aid in cleaning the snake as it is withdrawn.

Three-way trap elbow and cleanout system

A method for determining the spacial relationship between concealed elongated conductors wherein a test signal is coupled to a first concealed conductor and conductively coupled to a second adjacent concealed conductor. The relative direction of the current of the test signal on the second conductor is measured on opposite sides of the first conductor. An indication of the relative directions of the current of the test signal on opposite sides of the first conductor can be used to determine if the two conductors are separated or in contact with each other. If the relative direction of the test signal radiated from the second conductor is the same on opposite sides of the first conductor, then the two conductors are separated from each other. If the relative direction of the test signal radiated from the second conductor is opposite on opposite sides of the first conductor, then the two conductors are in contact with each other.

An instrument for measuring cathodic protection voltage levels receives a signal representative of an externally applied, full-wave rectified power line frequency cathodic protection potential, which is subject to electrical interference. The fundamental power line frequency component and odd harmonics of that fundamental component are removed to produce a filtered signal. Selected parameters of the filtered signal are measured to provide an indication of the adequacy of the cathodic protection potential.
