Plumbing leak detection is a crucial part of pipeline risk management. It allows the operator to take action in time to the leaks to avert further crisis. Various technologies are used to detect the leak from pipelines, depending on the sap’s nature in the pipeline and the leak’s size.
An early leak diagnosis method, capable of working in the high audio background of pipeline stations with little interference to typical station operations, is desirable for evading possible failure.
There are various leak testing techniques, ranging from simple to complex approaches. Let us look at some of the techniques.
Sub-division of DMAs by Internal Valving
When monitoring tests indicate that the leakage has escalated in a Direct Memory Access, internal valving can temporarily bisect the DMA into tight areas. Incase daytime valves closure causes supply issues, they can be closed during the night and opened again before dawn.
Professional plumbers monitor each sub-area using the DMA meter. The good part is that each sub-meter results can be observed by fixing the flow data lumberjack per unit meter before the test. At the end of the test, all the logged flow rates are compared with the DMA sub-division results.
Leaking sub-areas are audited, and standard sub-areas are ignored. However, some areas may be challenging to sub-divide since it may cause a lot of disruption. In this case, plumbers install meters on internal boundaries to create two DMAs, each gushing into another. The meters in such areas remain unread until the DMA monitoring indicates a night flow increase.
Step Testing
Step testing includes some extra work of sketching step test areas to recognize segments of pipework and valves. The process involves an installation of a flow meter on the input in each area code. This method aims to minimize the area’s size by shutting down the valves on each part of the pipe. Meter readers, in this case, keep a note of changes in the water flow rate. They keenly note the flow of water, and when there is a massive drop in water flow, they know that there is a leak in the pipe section that has been closed.
Step test is divided into two main sections that include the traditional and modern techniques. The traditional technique works by shutting valves in a backward manner towards the meter. It then comes back to open the valves once the test is finished. The traditional technique is obscure due to its supply interruptions and the likelihood of supply of dirty water.
The modern method is more advanced and widespread. It has a better flow meter and data logger technology. It comprises a sequence of small steps, segregating parts of the DMA for a short period.
The method uses a remote meter reading device, either a mobile or radio appliance placed on the meter. Flow rates are relayed to the site operators, whereby they view the results of the valve closure instantly, minimize the time the valves stay open and speed up its operation. Youngs water & Sewer also provides water pressure testing.
