  • Pondering the depths of the drip leg

    Hey,
    can anyone out there tell me how deep or long a drip leg should be for a given size gas line. The class and i were having this discussion yesterday. Are there standards for this. I've seen anything from a couple of inches to ten inches on 1/2" gas line. Any info on this matter would be greatly appreciated.

    One of my first days on the job an old timer said to me 6" no matter what size. The large diameter makes up for the increased flow rate

      I've always used 4", but that is just me.

        It's really a moot point today as most gas line do not collect condensate anymore, my understanding is its more for debris today, and I must say in all my years of plumbing I've never found anything inside an old drip leg that I have taken apart. And yes, I still install them.

          the 2006 ifgc doesn't mention anything about length. Section 408. I've alway gone for 6".

            Drip legs are no longer necessary, and a great way for a home owner to get himself in trouble!

                I seem to recall 6" for all pipe sizes but I can't say I remember where that came from. I've always used 6" and never had anyone comment.

                    The only use for a drip leg is to hold up the pipe if you don't have any strap iron on the truck.

                      Whatever sized nipple I can find rolling around in the back of my truck.


                      Never been given a specific sized drip leg.

                        4" here.

                        I'd heard a "rumor" they were no longer required..I'd still use 'em for the fact that they'll catch sediment or cutting oil before the appliance does.

                            Under the UPC it is a minimum of 3". Under the International Codes there is no minimum length.

                              upc. 1211.7.3 refer to 1212.7 can't say i've ever done this this is a sediment trap.

                              the drip leg is upc 1211.7.1 this is required where dry gas is not supplied.

                              what is the major difference between a drip leg and a sediment trap?
