Plumb Guard is designed to detect potentially dangerous voltages caused by either bad or missing earth points and leaky mains wiring on customer’s premises or if an under road borer drills through any power cables.

The unit is supplied with two large clamps and one earth stake. The clamps are attached to the metal water pipe. If the pipe is to be cut (for replacement or repair) the clamps should be placed each side of the cut. The earth stake is hammered into a good earth point. The leads between the clamps and the unit are five metres long and the earth stake lead is five metres long.

Once the unit is self tested, then attached to the pipe or under road borer, the unit will sound a loud alarm and bright flashing lights if the voltage on the clamps rises above 6V from the earth point. Once alarmed, the unit will maintain the alarm until switched off. Plumb Guard is housed in a solid waterproof case and is also shower proof from the front panel, so it can be used in the rain without any problems. All front panel parts are waterproof. Powered by a rechargeable battery and comes with an AC 240V charger with the option of a 12 VDC car charger.
