Abstract

A kit for non-invasively determining the presence of non-electrically conductive plumbing in a residence includes an electrical resistance measuring device having a main body and a resistance measuring circuit disposed therein and a display for indicating the value of the resistance measured by the resistance measuring circuit. The kit further includes at least two test probes which are in electrical communication with the resistance measuring circuit of the device. In a method for determining the presence of non-electrically conductive plumbing in the residence using the kit, one of the test probes is connected to an exposed portion of electrically conductive piping and the other is connected to a grounded conductor. When a low measured resistance is observed, as indicated by the device, the operator determines that the residence does not have non-electrically conductive plumbing. When a high measured resistance is observed, the operator determines that non-electrically conductive plumbing is present.

a main body;

a resistance measuring circuit, the resistance measuring circuit being positioned within the main body; and

an indicator, the indicator being in electrical communication with the resistance measuring circuit, the indicator displaying a low resistance indication when a low resistance is measured by the resistance measuring circuit and a high resistance indication when a high resistance is measured by the resistance measuring circuit, the indicator being positioned on the main body of the device; and

at least two testing probes, each of the testing probes having a first end and a second end disposed opposite the first end, the first ends of each of the testing probes being in electrical communication with the resistance measuring circuit;
