What is a drip leg on a furnace?
The rarely noticed sediment trap, or drip leg, is an important part of any gas appliance. These small pipes that appear to be extensions of the gas line serve the purpose of collecting sediment, debris, and other impurities that come through the gas line, catching them before they enter the appliance.
What is a gas drip?
Drip gas, so named because it can be drawn off the bottom of small chambers (called drips) sometimes installed in pipelines from gas wells, is another name for natural-gas condensate, a naturally occurring form of gasoline obtained as a byproduct of natural gas extraction.
Where are the drip legs on a gas line?
Sediment traps collect dirt, rust, and other debris in the gas line before it gets to the control valve of an appliance. Drips legs are used to collect water droplets. They are located in low areas of a gas line.
Where do you put a drip leg on a water heater?
A drip leg can be installed anywhere at the low point in the piping system if there is moisture in the gas to allow for the removal of the condensation. The outlet of the meter is one such location. Sediment traps are usually installed very close to the water heater or furnace valve.
What do you need to know about drip legs?
Sediment traps are required before an appliance. Sediment traps collect dirt, rust, and other debris in the gas line before it gets to the control valve of an appliance. Drips legs are used to collect water droplets. They are located in low areas of a gas line.
What’s the difference between drip legs and sediment traps?
Drip legs and sediment traps look the same, and are very often confused. Sediment traps are required before an appliance. Sediment traps collect dirt, rust, and other debris in the gas line before it gets to the control valve of an appliance. Drips legs are used to collect water droplets. They are located in low areas of a gas line.
Where do you put drip leg on gas heater?
Drip legs are basically for catching condensate and moisture in a gas line. A drip leg can be installed anywhere at the low point in the piping system, if there is moisture in the gas to allow for the removal of the condensation. The outlet of the meter is one such location.
Why does drip leg not work on gas stove?
Drip Leg. Dirt, dust, small particles flowing through the line will fall into the sediment trap and hopefully not clog the gas valve. It is not required (for natural gas) for an oven or stove. This type of appliance does not use gas in great quanities so it will not stir up particulate material laying in the line.
How big of a drip do you need for a water heater?
G2419.1 (408.1) Slopes. Piping for other than dry gas conditions shall be sloped not less than 0.25 inch in 15 feet (6.4 mm in 4572 mm) to prevent traps. G2419.2 (408.2) Drips. Where wet gas exists, a drip shall be provided at any point in the line of pipe where condensate could collect.
What’s the difference between drip leg and sediment trap?
However: Sediment traps are basically for the purposes of catching sediment and contaminates in a gas line. Drip legs are basically for catching condensate and moisture in a gas line. A drip leg can be installed anywhere at the low point in the piping system, if there is moisture in the gas to allow for the removal of the condensation.
