Detecting leaks in low-pressure systems effectively can be accomplished through the use of soapy water or electronic leak detection devices. When soapy water is applied to joints and connections, any escaping gas will create bubbles, indicating the presence of a leak. This method is straightforward and cost-effective, making it a practical option for routine maintenance and inspections.

Additionally, electronic leak detection devices offer a more advanced and sensitive means of identifying leaks. These devices can detect very small amounts of gas, making them particularly useful for applications where precision is critical. They often generate an audible or visual alert when a leak is detected, facilitating quick identification and resolution of potential hazards.

While visually inspecting all joints can help identify obvious leaks, it may not detect smaller or less visible leaks. Pressure loss calculations can indicate potential problems but require a comprehensive understanding of the system and may not pinpoint the exact location of a leak. Simply replacing old fittings is not an effective method for leak detection, as it does not verify whether a leak exists or pinpoint its location. Instead, it may lead to unnecessary expenses if leaks are not present in the fittings themselves.
