TL;DR
A sediment trap is a short dead-leg of pipe with a capped bottom tee installed in the gas line just before an appliance such as a water heater or furnace, where rust flakes, scale, and moisture drop out before reaching the gas valve. The IRC's fuel gas provisions require one at most appliances, with the trap leg at least 3 inches long.
What it means
A sediment trap is a short dead-leg of pipe with a capped bottom tee installed in the gas line just before an appliance such as a water heater or furnace, where rust flakes, scale, and moisture drop out before reaching the gas valve. The IRC's fuel gas provisions require one at most appliances, with the trap leg at least 3 inches long. Inspectors flag its absence often because debris in a gas valve is a common cause of nuisance shutdowns.
