Generally speaking electronic leak detection is used for locating leaks on underground water lines. Leaks above the slab and below raised foundations (wood floors), are certainly not discernible with standard leak detecting equipment and are superior and much more economically dealt with by standard signifies.

Finding the leak
Sewer and drain line leaks are finest positioned with sewer cameras. To begin with it ought to be determined that there's a leak below a concrete floor, ahead of initiating electronic leak detection. Signals are a hot spot around the floor, the sound of water operating 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 along with a water heater that will 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 surely a leak someplace. In the event the principal shut-off valve is closed along with the meter's needle stops, it indicates that the leak is within the house (constructing). Otherwise it's occurring among the meter and the dwelling.
Place of leak
As soon as it really is determined that the leak is inside the house, the house shut-off valve is usually reopened (causing the meter needle to resume movement) and also the hot water shut-off valve, located around the cold water inlet for the water heater, could be closed. If the needle once again stops moving, it signifies the leak is around the hot water line.
When it has been determined exactly where the leak is, the loss of water is often controlled by closing either the hot water heater shut-off valve, that will nonetheless leave you with all the permanent use of cold water, or by closing the house shut-off valve, if it is actually a cold water leak, which will leave you with no water. If there is not substantial water coming in to the dwelling, these valves can be re-opened for short term use after which re-closed in the course of instances of non-use. This makes it possible for the occupants to flush toilets, take showers, wash dishes and laundry, and so on., even though the diagnoses and repair process is getting implemented.
To perform the leak detection, the pipes are disconnected, ordinarily at the water heater, and pressurized with nitrogen. This specific gas is excellent for producing a "high-pitched" sound that is certainly effortlessly detected via a set of high-quality head phones using a sophisticated listening device. After the highest decibel of sound is situated, the leak is pin-pointed. Sometimes the sound will transfer through a channel of some type, normally plastic pipe wrapping plus the point of discovery may very well be a number of inches or feet away, but we have seasoned better than 95% accuracy with our electronic leak detection equipment.
