What should I do if the radiator has trachoma? Comprehensive analysis of repair methods and preventive measures

Recently, with the arrival of the winter heating season, the problem of radiator leakage has become one of the hot topics on the Internet. In particular, water seepage problems caused by trachoma (tiny holes) in radiators have troubled many families. This article will provide you with structured solutions based on the hot discussion data of the past 10 days.

1. Popular discussion data on radiator trachoma across the Internet

2. Common symptoms of radiator trachoma

According to feedback from netizens, trachoma problems usually manifest as:

1. Tiny water seepage points (diameter 1-3mm)

2. Rust spreads radially

3. Leakage becomes more obvious when the pressure drops

4. Frequently occurs at welded joints

3. Comparison of 6 practical repair solutions

Epoxy resin gluetemporary emergency1-3 months20-50 yuan
Cold welding technologysmall area trachoma2-5 years100-300 yuan
Argon arc welding repairLarger holesMore than 5 years200-500 yuan
Replace single component chipmultiple trachomaMore than 10 years500-1500 yuan
Professional leak-stopping agenthidden location3-8 years80-200 yuan
Rubber gasketSeams1-2 years10-30 yuan

4. Detailed repair steps (taking epoxy resin as an example)

1.close valve: First close the water inlet and return valve and drain the accumulated water.

2.surface treatment: Use sandpaper to polish the rust to reveal the true color of the metal.

3.Cleaning and disinfection: Wipe with alcohol to remove oil stains

4.Mix glue: Mix epoxy resin according to the instructions.

5.filling compaction: Use a scraper to press the colloid into the hole.

6.Curing and waiting: Keep away from water for 24 hours

5. Five key measures to prevent trachoma

1. Do a pressure test every year before heating (recommended 0.8MPa)

2. Water quality treatment: install a filter and keep the pH value at 7-8.5

3. Maintenance with full water during non-heating season to prevent oxidation

4. Avoid collision with sharp objects

5. It is recommended to replace old radiators (more than 8 years old) in advance

6. Professional advice

According to interview data from heating company technicians:

Radiator typeaverage life spanProbability of trachoma
cast iron radiator15-20 years12.7%
Steel radiator10-15 years8.3%
Copper aluminum composite20-30 years2.1%

Consider replacement rather than repair when:

• More than 3 trachoma appear on a single set of radiators

• Leakage occurs again within 2 months after repair

• Accompanied by extensive rust peeling

7. Cost reference (latest data in 2023)

Servicesfirst tier citiesSecond and third tier cities
Door-to-door testing fee80-150 yuan50-100 yuan
Welding repair300-600 yuan200-400 yuan

system flush200-400 yuan150-300 yuan

Warm reminder: emergency maintenance costs may increase by 30% in winter, and it is recommended to complete the maintenance in autumn. Through the detailed guidance in this article, you can effectively deal with the problem of radiator trachoma and ensure a warm winter.
