Fire protection pipes are important carriers of water for fire protection. Once a leak occurs and needs to be repaired, how should the cause of the leak be found? How to repair?
1、First, close the fire valve, find the leaking section of the fire protection pipe network, observe the ground and find the location of the leaking fire hose. This method is simple to use, the disadvantage is that if the fire hose network is complex, it is difficult to determine the exact location.
2, the use of listening methods to confirm the location of the leak. In the dead of night, when the amount of water leakage is large, there is a certain probability of hearing the sound to confirm the location. Or use a professional pipe leak detector to determine the location of the leak. In general, the basic detection method is, connect the pipe leak detector host, headphones, sensors. Turn on the switch, wear headphones, place the pipeline leak detector sensor on the road above the pipeline, placed step by step according to the length of the pace, step by step listening, the closer to the leak, the stronger the signal, the farther away from the leak the weaker the signal, by comparing the signal strength between different points to achieve the purpose of detecting leaks.
3、Confirm the cause of leakage, usually the cause of leakage is the fire protection pipe network paint peeling, rubber ring extrusion deformation, step cracks raw seams, etc.
4、After confirming the cause of the leak, we can repair the leak by using external plugging agent, replacing the rubber ring, replacing the pipe network and other methods.
5、As for the repair cost, if it is within the repair period, you can ask the developer to repair and pay the related cost. If it is not within the repair period, you can consult the property company or construction administration department to confirm the related cost sharing responsibility.
