Typically speaking electronic leak detection is used for locating leaks on underground water lines. Leaks above the slab and below raised foundations (wood floors), are usually not discernible with conventional leak detecting equipment and are greater and more economically dealt with by traditional means.

Discovering the leak
Sewer and drain line leaks are finest located with sewer cameras. To begin with it need to be determined that there's a leak below a concrete floor, prior to initiating electronic leak detection. Signals are a hot spot on the floor, the sound of water running when all plumbing fixtures are not in use and water coming from someplace on the floor (ground floor), or at a low point on a wall (1st story). Hot water coming from a cold tap in addition to a water heater that does not shut off, or re-ignites swiftly, are other signs. At that point one ought to verify the water meter. In the event the needle is moving and no plumbing fixtures, or bibs, are in use, then there is unquestionably a leak somewhere. In the event the major shut-off valve is closed and the meter's needle stops, it indicates that the leak is within the house (building). Otherwise it truly is occurring between the meter and also the dwelling.
Location of leak
After it's determined that the leak is within the house, the house shut-off valve could be reopened (causing the meter needle to resume movement) and the hot water shut-off valve, situated on the cold water inlet towards the water heater, could be closed. If the needle once again stops moving, it means the leak is on the hot water line.
After it has been determined exactly where the leak is, the loss of water could be controlled by closing either the hot water heater shut-off valve, which will nonetheless leave you together with the permanent use of cold water, or by closing the house shut-off valve, if it really is a cold water leak, that will leave you with no water. If there is certainly not substantial water coming in to the dwelling, these valves is usually re-opened for short term use and then re-closed in the course of instances of non-use. This allows the occupants to flush toilets, take showers, wash dishes and laundry, etc., although the diagnoses and repair process is becoming implemented.
To carry out the leak detection, the pipes are disconnected, usually at the water heater, and pressurized with nitrogen. This specific gas is excellent for creating a "high-pitched" sound that is certainly simply detected by way of a set of high-quality head phones using a sophisticated listening device. After the highest decibel of sound is positioned, the leak is pin-pointed. Sometimes the sound will transfer by way of a channel of some sort, typically plastic pipe wrapping and the point of discovery may be a couple of inches or feet away, but we've experienced much better than 95% accuracy with our electronic leak detection equipment.
