What to do if there is water leakage under the heater
With the arrival of winter, the frequency of heating use increases, and the problem of heating leakage has become one of the hot topics recently. Many users reported on social platforms and home forums that there was water leakage under the heater and urgently needed a solution. This article will provide you with detailed handling methods and precautions to help you quickly deal with this problem.
1. Common causes of heating leakage

Heating leakage is usually caused by the following reasons. The following are the statistics reported by recent users:
| Reason | Proportion | Typical performance |
|---|---|---|
| Pipe joint is loose | 35% | Water dripping from the interface |
| Radiator corrosion | 25% | Rust along with water leakage |
| Damaged valve | 20% | Water dripping continuously around the valve |
| System pressure is too high | 15% | Water seepage from multiple locations at the same time |
| other reasons | 5% | Water leak from unknown location |
2. Emergency steps
When you find your heater is leaking, follow these steps:
1.close valve: Immediately close the water inlet and return valves of leaking radiators (usually located at the bottom of the radiator). If the main pipe is leaking, the indoor main valve needs to be closed.
2.reduce losses: Use towels, absorbent cloth, etc. to block the leakage point, and place a bucket to catch the water to avoid soaking the floor.
3.preliminary inspection: Wipe the leaking area with a dry cloth and observe the specific leaking point:
| Leak location | Possible reasons | temporary measures |
|---|---|---|
| Interface | Seal aging/looseness | Wrap with raw material tape |
| Radiator body | Blisters/Corrosion | Apply waterproof glue |
| Bleed valve | Valve core damaged | Replace the bleed valve |
4.Contact maintenance: It is recommended to contact professional heating maintenance personnel. Self-repair may cause the problem to worsen.
3. Preventive measures
Based on the maintenance recommendations provided by your heating company, the following precautions should be taken:
1.Regular inspection: Check the status of all interfaces and valves before the heating season, and replace aging seals in advance.
2.System maintenance: Maintenance should be filled with water during the non-heating season to prevent internal oxidation and corrosion of the pipes.
3.pressure monitoring: Keep the system pressure between 1.5-2Bar. Excessive pressure can easily lead to water leakage.
| maintenance items | Recommended frequency | Things to note |
|---|---|---|
| Pipeline inspection | 2 times a year | Focus on checking interfaces and elbows |
| Valve testing | 1 time per year | Check switch flexibility |
| System cleaning | every 3 years | Professional chemical cleaning |
4. Maintenance cost reference
According to recent quotations from housekeeping service platforms, the costs of common maintenance projects are as follows:
| Maintenance items | Cost range | Warranty period |
|---|---|---|
| Replace valve | 80-150 yuan | 1 year |
| Pipe leak repair | 120-300 yuan | 2 years |
| Radiator replacement | 400-800 yuan/group | 3 years |
5. Special reminder
1. Do not use electrical appliances when there is water leakage to prevent the risk of electric leakage.
2. Steel radiator leaks must be dealt with within 24 hours, otherwise corrosion will be accelerated.
3. If water leakage causes the wall to become wet, it must be dried in time to avoid mold.
4. Keep the maintenance certificate. Most community heating systems have a 2-year quality guarantee period.
Through the above measures, you can effectively deal with the problem of heating water leakage. It is recommended that users collect this article and do preventive inspections before the heating season to ensure a warm winter.
