Checking for leaks
The tightness of the radiator is checked in a bath of water.
1. After plugging the radiator pipes, supply air to it under a pressure of 0.1 MPa (1 kgf/cm²) and lower it into a bath of water for at least 30 s. No air leakage should be observed.
2. If minor damage to a brass radiator occurs, solder it with soft solder, and if significant, replace the radiator with a new one.
