How to check whether floor heating is leaking
The floor heating system is one of the important ways of heating modern homes. However, if there is a water leakage problem, it will not only affect the heating effect, but may also damage the floor or wall structure. The following are the inspection methods and precautions for floor heating leaks that have been hot topics on the Internet in the past 10 days to help you quickly troubleshoot the problem.
1. Common causes of floor heating leakage
| Reason | Description |
|---|---|
| Pipeline aging | After long-term use, floor heating pipes may crack or corrode |
| Improper construction | Failure to perform standard operations during installation resulted in loose pipe connections. |
| external damage | Pipe damage caused by decoration or heavy objects squeezing |
| Water pressure is too high | System pressure exceeds design standards, causing pipe explosion |
2. Steps to check for floor heating leaks
1.Observe the floor and walls
If you find local bulges on the floor, blackening of the tile gaps, or water stains on the wall, it may be a sign of floor heating leakage. Pay special attention to wet areas such as bathrooms and kitchens.
2.Check the water distributor
| Check items | normal state | abnormal behavior |
|---|---|---|
| pressure gauge | Stable at 1.5-2Bar | pressure continues to drop |
| Valve interface | Dry without water droplets | There are obvious water stains or rust spots |
3.Professional testing methods
(1) Infrared thermal imager: locate water leakage points through temperature differences
(2) Pipeline leak detector: uses the principle of sound waves to detect hidden leaks
(3) Pressure test: After shutting down the system, pressurize it to 1.5 times the working pressure and observe the pressure changes.
3. Emergency measures
| situation | Coping methods |
|---|---|
| Found a slight leak | Close the water inlet valve immediately and contact a professional |
| Lots of water leaks | Cut off the power supply and drain the water to prevent short circuit. |
4. Suggestions on preventing water leakage
1. Do a system pressure test every year before heating
2. Avoid drilling or nailing holes in the ground
3. Choose high-quality pipes that are resistant to high temperatures and corrosion.
4. Keep the floor heating pipeline drawings during decoration
5. Maintenance cost reference (market data in the past 10 days)
| Maintenance items | Cost range |
|---|---|
| Local pipe repair | 300-800 yuan |
| Water distributor replacement | 500-1500 yuan |
| Whole house plumbing repaving | 80-150 yuan/square meter |
Through the above systematic inspection methods, hidden dangers of floor heating water leakage can be discovered in time. It is recommended to ask professionals to conduct a comprehensive inspection every 2-3 years to ensure the safe operation of the heating system. If any abnormality is found, do not disassemble it yourself, but contact a qualified maintenance team to handle it.
