Drip Leg

How important is the installation of a "drip leg" in a gas line (in my case, propane)? I'm in an older house and none were installed, but now that I'm doing some remodeling I'm thinking maybe I should add them before my oven and my water heater. Any suggestions?

The drip-leg is a preventative measure. If you have steel pipe, there is a tendancy to flake. The drip-leg catches these, heavier than gas, particles preventing them from clogging orfices and valves. Good luck.

As per NFPA 54 (National Fuel Code), drip legs (or sediment trap (the proper term), are not required on ranges. They are required on water heaters.
