I have a propane gas stove. The propane enters the house with copper tubing, looks to be about 3/8" dia. The furnace is connected with this same copper and thats the only other appliance. The problem is that the kitchen stove gets moved for cleaning and the pipe has to bend. This is the second time in the past few years it started to leak where the compression fitting connects to the stove, which is connecting to 1/2" black pipe. First, should compression fittings be used or should they be flared? Second, would it be legal to connect the copper to black pipe at the floor, and run a regular flexible gas pipe to the stove, or would it be better to connect the flex pipe right to the copper with a valve in between. (the valve right now is right on the end of the black pipe on the stove, but the leak always occurs before it, which means shutting off the whole house. In the summer that is not a problem, but in winter that means no heat. (which is why I will not let the wife move the stove in winter).
I'm not too worried about code, this is a rural farm and no one will check. I AM worried about safety, not to mention getting tired of repairing this thing everytime the stove is moved.
Thanks
