Slow gas flow - could there be a leak?

Gas into a home is already at a certain PSI. It doesn't need to build up pressure. You should check for leaks and blockages. If there are none then you may have a sizing issue. Gas is like water flow. If you divert water from a river 5 different ways equally, the flow at the end of a divert is 1/5 of the original river. So to get more water in a divert, you got to increase the amount of water in the original river. To do that for gas, you need to use larger size gas pipe from the main gas meter. You can find natural gas piping size carts online. This type of work should be done by a professional.

You will want to try testing out your gas lines to see if there are any leaks. Here's a simple and quick method:

Step 1: Get some water.

Step 2: Get some *dish* soap, or bubble bath (any kind of soap that will give you a myriad of foam).

Step 3: Mix the water and said soap together until you have an abundance of foam at your disposal.

Step 4: Get a small brush (a trimming-paint brush is ideal) and put some of the foam (not the liquid solution) onto it.

Step 5: Spread the foam all around the seams of the gas pipe where you suspect there might be a leak (in your case, right at the valve-stem may be where you want to start).

Step 6: Look at the results--if the foam starts gyrating, popping, and expanding, then unfortunately, you have a gas leak; however, if the foam just sits there, that location is leak-free and you can either move on to another questionable area, or be done!
