we are modifying a duplex to turn a small closet into a laundry area. in doing this we need to tap into the existing gas line to add a tee that will supply the gas dryer (yes we have sufficient intake air), but i would like to know if we can use a 3/4 union to attach old and new lines, or do i need a right/left nipple to be code compliant.
Does anyone have advice on the best way to terminate a gas valve for the laundry area? A pipe going out the wall with a 1/4 turn valve is a bit rustic. I am wondering if there is a gas housing something like the water/waste housing for the laundry supply, or the nice little water on/off housing for an ice-maker.
Sure do. These just hit the market and they're pretty slick. They're new enough that you might need to go to a plumbing supply house for them....I doubt the box stores will have them. Sioux Chief just mailed me the literature on them late last week.
1/2" and 3/4" NPT pipe thread versions are available for threaded gas pipe.
