I have a 1.25 inch incoming gas line to my 2 story home. This feeds 2 fireplaces ( 1 upstairs , 1 downstairs) that are close to one another. It also feeds a hot water heater.
Former homeowner teed off the water heater line ( 1/2 inch) located in the garage and added 2 runs. One run of black pipe , 1/2 inch, to the laundry room that is approx 25 feet. Another 1/2 inch run to backyard (wrapped black pipe) for BBQ grill that is approx 70 feet. The measurements are based on actual pipe feet.
The hot water heater has a cutoff valve, as does the BBQ run. Actually the BBQ has 2 cutoffs - one in the garage near the T and the other at BBQ stub.
The laundry room stub has a cutoff valve right inside the room.
I want to do 2 projects.
Project 1
First, I have never used the gas dryer stub and I want to move it. The pipe is installed along the garage baseboards and crosses my home entry bottom sill. I don't like it there.
Since I do not have a cutoff valve at the T for the dryer line, I plan on cutting off the gas at the meter.
I will allow the gas water heater pilot light to shut off and then shut off the valve.
I will open the BBQ valves and let it bleed. Then I will shut off the BBQ valve.
Then cut the dryer line pipe near the T and remove the entire 25 feet of pipe.
Install a 4 inch pipe and a new cutoff valve at the T . I can use this line for other purposes.
Finally, open the meter valve, open (slowly) the water heater valve, open the BBQ valve. Check for leaks using the soapy water method. Relight the water heater.
Project 2
I want to relocate the BBQ. Basically move the stub about 10 feet and add a small firepit ( 18" burner). Total additional pipe feet is about 15 feet. The total linear distance from the meter to the new BBQ stub is approximately 70 feet.
I will use the 1/2 inch pipe removed in Project 1, wrapping it in 20ml PVC pipe tape ( from HomeDepot).
Here are my questions.
Is the plan for project 1 for gas shutoff, bleed, and cutting the pipe reasonable? Have I missed a step? Is there a better alternative? I am concerned about air in the line after I cut the pipe, and the relighting steps. How do I ensure that air is bled from the lines before relighting the heater and BBQ? Can I use the newly installed stub and cutoff valve to bleed the air by attaching a hose , taping it well, and running outside the garage? What about the 2nd story fireplace?
For Project 2.
When estimating BTU throughput, do you measure the linear distance from the meter to the farthest stub, or do measure the actual pipe distance, with all turns and elevation changes?
Thank you.
