is it a problem connecting a larger gas pipe to a smaller gas pipe?
I have a low pressure residential gas system with a half inch gas pipe out to my patio that I use for a natural gas BBQ. Works fine.
I would like to add a T to the line and run a another 21 foot line off the BBQ line to use for a gas fire pit or a patio heater. However I was given 3/4 inch pipe I would like to use for that line. There are other reasons I would like to use that particular pipe.
I assume connecting larger pipe to smaller pipe results in a decrease in velocity and pressure, but no change in volume. I am also assuming that is really not a problem.
Right/wrong/maybe? Any suggestions or thoughts?
