Question: 1 / 400

When should a soldered joint be tested for leaks?

Immediately after soldering

After the joint has cooled

A soldered joint should be tested for leaks after the joint has cooled. This is important because immediately after soldering, the joint is still very hot, and any testing for leaks could lead to inaccurate results. The heat can cause the solder to expand, which may temporarily prevent a leak from being detected. Testing the joint once it has cooled allows the solder to contract and settle, providing a more accurate assessment of the integrity of the joint. Ensuring that the joint is cool also prevents potential injury and allows for a proper inspection of the soldered area, ensuring safety and reliability in plumbing systems.
