Which statement about drip tees placement in gas lines is correct?

• A. Drip tees may be installed anywhere in the run.
• B. Drip tees must be placed after the meter's first change of direction and for any horizontal-to-vertical change.
• C. Drip tees are optional.
• D. Drip tees must be installed before any changes in direction.

Answer: (B)

Drip tees provide a convenient drain point in a gas piping run to collect and remove condensate and any liquids that can accumulate in the line. They are placed to create a low point where liquids can settle and be vented off without entering the meter, regulator, or appliances. Placing a drip tee after the meter’s first change of direction ensures that any condensate formed in the line is captured soon after it leaves the meter, so it won’t travel downstream into critical components. Additionally, installing a drip tee at any horizontal-to-vertical change takes advantage of gravity: liquids will tend to collect at the low point of a vertical leg, where they can be drained safely rather than remaining in the horizontal run and possibly being drawn into equipment. In short, this specific placement helps keep the gas flowing cleanly and protects the meter and downstream appliances from moisture and debris.
