Moving into a new house within 3 weeks.
Need to install a gas line for the dryer.
While I'm at it, planning on putting in a line for the outsde BBQ.
What dia. of line would be used for these installations.
It would depend on whatsize line is coming into your house and what you have in gas appliances now. Generally you would go 3/4 to 1/2 to 1/2 tee to each of them. That would be a 1/2 inch line to each. But don't split them off of a 1/2 inch line.
