Did you know there is a difference between a sediment trap and a drip leg in propane systems?

A drip leg and a sediment trap are both used to protect propane appliances and piping systems, but they serve different purposes:

Drip leg:

• Collects condensation in propane piping systems to prevent it from running back into the propane tank or regulator.

• A drip shall be provided at any point in the line of pipe where condensate could collect, that is accessible and not anywhere likely for condensate to freeze.

  
  

Sediment trap:

• Prevents sediment and debris, such as rust particles or dirt, from entering a propane appliance or regulator.

• Also known as a dirt leg.

• Can collect particles from the installation process or from the propane supply itself.

In Texas, all sediment traps must be installed in accordance with NFPA 54. NFPA 54 states: sediment trap shall be installed downstream of the appliance shutoff valve as close to the inlet of the appliance as practical at the time of appliance installation.
