Leak detection | Power and Water Corporation
A meter leak check is easy for you to do at any time. Aim to check for leaks regularly. Set yourself a reminder, such as when your bill arrives. Turn off the water in your home or business. Make sure no one uses any taps or flushes the toilets. Go to your water meter and watch for any movement on the dial.
Air Sealing Your Home | Department of Energy
Sealing cracks and openings reduces drafts and cold spots, improving comfort. The recommended strategy is to reduce air leakage as much as possible and to provide controlled ventilation as needed. Before air sealing, you should first: Detect air leaks. Assess your ventilation needs for indoor air quality.

Light an incense stick and carefully pass it around the edges of common leak sites.
Leakage Current Measurement Basics | Fluke
Any imbalance current comes from leakage from the conductors to ground or elsewhere. To measure this current, a leakage clamp meter should be able to read less than 0.1 mA. For example, taking a measurement on a 240 V ac circuit with all loads disconnected might result in a value of 0.02 A (20 mA) leakage.
