How to repair leaking geothermal pipes
Leakage from geothermal pipes is a common problem in home heating systems. If not dealt with in time, it may cause damage to the floor, mold on the walls, and even affect the overall heating effect. This article will combine the hot topics and hot content on the Internet in the past 10 days to provide you with a detailed maintenance guide and attach structured data for reference.
1. Common causes of geothermal pipe leakage
Leakage in geothermal pipes is usually caused by:
| Reason | Description |
|---|---|
| Pipeline aging | After long-term use, the pipe material ages and causes rupture. |
| Improper installation | Failure to follow specifications during construction resulted in loose pipe connections |
| external force damage | Pipes are damaged due to renovation or heavy objects squeezing them |
| water quality issues | Impurities in the water corrode the inner wall of the pipe |
2. Detection methods for water leakage in geothermal pipes
Before repairing, the location of the leakage point needs to be confirmed. The following are common detection methods:
| method | Operation steps |
|---|---|
| observation method | Check the ground for water damage or moisture |
| stress test | After turning off the water source, use a pressure gauge to check whether the pipeline pressure drops. |
| Infrared detection | Use infrared thermal imaging cameras to locate areas with abnormal temperatures |
3. Repair steps for leaking geothermal pipes
Repair methods vary depending on the cause and location of the leak:
| Repair type | Operation steps |
|---|---|
| slight water leak | Use special repair glue or leak-stopping agent to temporarily repair |
| Water leaking from the connection | Retighten or replace connections |
| Broken pipe | Cut the damaged part, replace with new pipe and hot-melt connection |
4. Maintenance precautions
1.Turn off water and power: Be sure to turn off the main valve and power supply of the geothermal system before maintenance to avoid electric shock or flooding.
2.Professional tools: It is recommended to use professional tools such as hot melt machines and pipe shears to ensure the quality of repair.
3.Test acceptance: A pressure test is required after repair to ensure there is no secondary leakage.
4.Regular maintenance: Check the condition of the pipes and clean the filters before the heating season every year.
5. Maintenance cost reference
The following is the cost range of different repair methods (data from recent market research):
| Maintenance items | Cost range (yuan) |
|---|---|
| Simple plugging | 200-500 |
| partial pipe replacement | 800-1500 |
| Overall renovation | More than 3000 |
6. Preventive measures
1. Choose corrosion-resistant PB or PE-RT material pipes
2. Reserve expansion joints during installation to avoid thermal expansion and contraction.
3. Regularly check the sealing of the water distributor interface
4. It is recommended to have professional pipe cleaning every 3 years
Through the above structured analysis and practical suggestions, we hope to help you effectively solve the problem of geothermal pipe leakage. If the leakage situation is complicated, it is recommended to contact a professional floor heating repair company to deal with it.
