What to do if the heating vent valve leaks
With the arrival of winter, the frequency of heating use increases, and many families may encounter the problem of leaking heating vent valves. This not only affects the heating effect, but may also cause water waste and even household damage. This article will introduce in detail the causes, solutions and preventive measures of leakage in the heating vent valve to help you quickly deal with this problem.
1. Reasons why the heating vent valve leaks

Leakage in the heating vent valve is usually caused by the following reasons:
| Reason | Description |
|---|---|
| Valve is aged or damaged | After long-term use, the valve seal ring is worn or the valve body is corroded, causing water leakage. |
| System pressure is too high | The pressure in the heating system exceeds the tolerance of the valve, causing water leakage. |
| Improper installation | The valve is not tightened or the sealing material is insufficient, causing water leakage. |
| Impurities clog | Scale or impurities in the pipeline can block the valve and affect the sealing performance. |
2. Solution to leakage of heating vent valve
For different causes of water leakage, the following solutions can be taken:
| Solution | Operation steps |
|---|---|
| Tighten the valve | Use a wrench to lightly tighten the bleed valve and check if water is still leaking. |
| Replace sealing ring | Turn off the heating system, remove the valve and replace the sealing ring or the overall valve. |
| Adjust system pressure | Contact the property management or heating company to reduce the system pressure to the normal range. |
| Clean up impurities | Remove and clean the valve after closing it, or use professional descaling agent to clean the pipe. |
3. Measures to prevent leakage of heating vent valve
To avoid water leakage from the heating vent valve, you can take the following precautions:
| measures | Description |
|---|---|
| Regular inspection | Check valves for looseness or corrosion every year before the heating season. |
| Install filter | Install a filter in the heating system to reduce impurities from entering the valve. |
| Avoid frequent deflation | Excessive deflation times will accelerate valve wear, so it is recommended to operate as needed. |
| Choose quality valves | Purchase branded valves that are corrosion-resistant and have high sealing properties. |
4. Professional maintenance suggestions
If self-treatment is ineffective or the valve is severely damaged, it is recommended to contact professional maintenance personnel. Here are some things to consider when choosing a repair service:
| Things to note | Description |
|---|---|
| Check qualifications | Confirm that the maintenance company is qualified to repair the heating system. |
