When there is a hole in the radiator that causes water leakage, we first need to take appropriate measures to fix the problem. Below I will answer for you in a professional tone.
Repairing a hole in a radiator is a relatively simple task that can be done with the following steps:
Prepare tools and materials: You'll need a screwdriver, a piece of cloth or tissue, a small piece of metal (such as copper), and a sealant that can withstand high temperatures.
Turn off the heating system: Make sure to turn off the entire heating system and wait for it to cool down before making repairs. This avoids scalding and further water damage.
Clean and prepare the area of the hole: Use a cloth or paper towel to clean the area around the hole and make sure the surface is dry. This provides better adhesion.
Repair the hole: Place the piece of metal on the location of the hole and use a screwdriver to gently press it. Apply the sealant evenly to the hole, making sure the metal sheet is completely covered and fits against the surface of the radiator.
Wait for the sealant to dry: Follow the sealant's instructions and wait for a while to ensure that the sealant is completely dry and fixed.
Restore the heating system and check the repair: Turn the heating system back on and see if there are any water leaks. If the patching is successful, you should be able to use the radiator normally without water leakage issues.
As for the durability and after-sales support after repair, it depends on a variety of factors, such as the quality of the repair, the material of the radiator and the conditions of use, etc. If you follow the steps above to repair properly, and with the proper materials and processes, repaired radiators can often last for a long time without water leakage issues.
However, as each situation and equipment is different, we recommend that you consult with a professional radiator repairer or contact the manufacturer for accurate after-sales support information before patching. They can provide you with more specific recommendations and solutions to ensure the effectiveness and safety of the fix.
