Methods Used for Meter Tampering

• Spiders - small holes are drilled into the meters and live spiders or spiders' eggs crammed into them. The spiders' webs slow down the metering mechanism, giving a false reading.
• Needles - pins are inserted into a hole, slowing down the meter's recording wheel to give a flash reading or even a zero usage.
• Magnets - small magnets attached to the outside of the meter casing will stop the meter from registering, or slow it down.
• Chewing gum - gum is often used to stop the meter completely but it is taken out just before the meter reading is taken.
• Bypass - meters are removed and power sourced illegally from underground cables and overhead wires.
