Plumber San Diego "Recommends". Especially when doing a gas line, that the work should always be done by a Professional.
First of all there is something called *The Plumbing Code Book, that should always be used, and it is here were a plumber learns to install a gas line, properly. Through applying the Code Book to said project.
In plumbing school were I went for 2 1/2 years through the P.H.C.C. back in 1984, wow sounds like a long time ago. (and 1 year to contractors school).
This was when, I learned what is called, sizing of a gas line, using The Plumbing Code Book, using charts based on total amount of fixtures, (gas appliances and or btus and the total distance, in the P.H.C.C.).
Which basically stands for The Plumbing Heating Cooling Contractors.
Or said another way (K.I.S.S. Keep it simple silly) it is the length from the meter to your most distant gas fixture(your total distance), and (the total btus of the gas appliances), will give you the line you should use on the chart. And than you draw your isometric.
You basically come up with a Isometric drawing ( a sketch on paper) which helps you to know which line in the chart you should use, (total btus of appliances and total distance),for installing appliances, which this is the right way.
And this method is always done by Plumber San Diego, (myself).
So once you now which line to use by total btus, and distance. You will use that line on the chart(in the Code Book).
It will tell you in the code book how many appliances you can install in that line, based on the total distance and total btus, basically a mathematical equation.
So this way there is no guess work but rather just checking a graph or chart and staying just on that line, so as to figure out, how many appliances are required for that amount (x) of appliances and total distance, it's pretty straight forward, and of course you check and double check.
And if your like me I probably check again. The total appliances and total distance several more times, and like I said just stay in that same column.
San Diego Plumbing Repair: Locating a Gas Line Leak.
When a Plumber San Diego is looking for a gas line leak, the following steps are completed. What is done first of all is to disconnect everything and install a cap at each connection accept one.
Here is were the pressure gauge valve is installed basically a gauge with a air connection like on a bicycle tire. Then you fill the gas line with air.
Of course All gas appliances have been capped off first before filling line with air, so every outlet is capped at each gas line outlet.
Except for one, where you install a gauge at outlet (called a gas test gauge), here is were you fill the line with air, if all the outlets are not capped air will leak and line will not be able to be pressurized.
Then what you do is look for the leak, (with a soap and water mixture in a spray bottle).
There is also a liquid that is sold at major hardware stores to locate leaks, and there is even what is called gas leak location equipment or tools.
Anyways so you check with a bottle with soap and water, or liquid (leak locating liquid), from hardware store.
What will occur is that when you locate the leak (air leak), on the gas line. It will begin to bubble, and so this the section in need of the Plumbing Repair and or replacement of the line.
And than when leaky pipe (filled with air) is repaired what must always be done is to fill again with air to check. If repair was done correctly(to recheck).
One last thing, Plumber San Diego always recommends that work (San Diego Plumbing Repair) be done by a Professional.
And you should also always check for your local Code requirements, regarding your vicinity.
