Where should gas drip legs not be installed to prevent freezing?

Gas drip legs should not be installed in rooms that can freeze because low temperatures can cause condensation to form in the drip leg, leading to the accumulation of liquid that could freeze. When the gas condenses and then freezes, it can create blockages that disrupt the flow of gas, potentially leading to unsafe conditions.

By avoiding installation in areas susceptible to freezing temperatures, many potential issues with gas supply systems and safety are mitigated. This understanding is crucial for maintaining safe and effective gas plumbing systems, as preventing freezing helps ensure that the gas remains in a gaseous state and can be transported without interruption or risk of hazard.

While gas drip legs are best kept out of unheated buildings, garages, and attics, it is especially important to consider rooms that can freeze because these environments can often be more unpredictable, leading to increased risk.
