Question: 1 / 400

What method can be used to test for gas leaks in a heating system?

Using a pressure gauge

Applying a soap and water solution

Applying a soap and water solution is a widely accepted and effective method for testing gas leaks in a heating system. When a soapy solution is applied to the fittings, joints, or areas suspected of leaking, the presence of a gas leak will create bubbles. This visual confirmation is a straightforward and practical way to identify leaks, as the bubbles will form at the site of the escape of gas.

In addition to being a simple, non-invasive testing method that does not require specialized equipment, this approach provides immediate feedback on the integrity of the system. It is commonly used by technicians because of its effectiveness and ease of use, making it a staple in the routine maintenance and troubleshooting of gas heating systems.
