How can you tell if the floor heating is leaking?
As an important way of heating modern homes, the floor heating system also brings hidden dangers of water leakage due to its concealment. If it is not discovered and dealt with in time, it may lead to floor damage, wall mold and even structural safety hazards. The following are methods and response strategies for determining floor heating leakage that have been hotly debated on the Internet in the past 10 days, clearly presented to you based on structured data.
1. Common signs of floor heating leakage
| phenomenon | Specific performance | Hazard level |
|---|---|---|
| ground anomaly | Part of the floor is bulging and the gaps between the tiles are black. | ★★★ |
| wall changes | Water seepage marks on the corners and peeling off of the wall coverings | ★★☆ |
| Abnormal cost | Water bill suddenly increased (over 3 tons per day) | ★☆☆ |
| Pressure gauge fluctuation | The pressure drops by more than 0.5Bar within 24 hours | ★★★★ |
2. 4 methods to accurately detect water leakage points
| Detection method | Operation steps | Accuracy | cost |
|---|---|---|---|
| Infrared thermal imaging | Locating leaky areas through temperature differences | 85%-90% | 300-500 yuan/time |
| sonic detection | Capturing sound wave signals of pipe leakage | 70%-80% | 200-400 yuan/time |
| Fluorescent agent detection | Inject fluorescent dye to observe the bleeding point | 60%-75% | 150-300 yuan/time |
| Segmented stress test | Pressure testing of pipelines section by section | More than 95% | Professional construction required |
3. Emergency treatment plan
1.Close the valve immediately: Locate the main valve (usually the red handle) on the water distributor and turn it clockwise until it is fully closed.
2.cut off power: If the leakage area involves a circuit, the corresponding circuit in the distribution box must be closed immediately.
3.Drainage treatment: Use an absorbent towel to cover the leaking point. In severe cases, a small water pump can be used (it is recommended to keep it on hand).
4. Maintenance cost reference
| Maintenance items | Material fee | Labor cost | Construction period |
|---|---|---|---|
| Pipe joint replacement | 50-100 yuan | 200-300 yuan | 2-3 hours |
| PE-RT pipe welding | 80-150 yuan/meter | 400-600 yuan | half a day |
| Whole house rewiring | 80-120 yuan/㎡ | Starting from 3,000 yuan | 3-5 days |
5. Preventive measures
1.annual stress test: Conduct a 1.5 times working pressure test before the heating season (recommended value: 0.8MPa).
2.Install leak alarms: The smart sensor can monitor humidity changes in real time, with a market price of 150-400 yuan.
3.Avoid drilling holes in the ground: When decorating, you need to ask for the floor heating pipeline distribution map, and the drilling depth should not exceed 3cm.
Special tips:According to the "JGJ142-2012 Technical Regulations for Floor Radiant Heating", the warranty period of the floor heating system should not be less than 2 heating seasons. If there is water leakage, the original construction unit should be contacted first to deal with it.
