Why is so important check gas Line.
1. I have seen so many flex line damaged.
2. So many gas line are very loose.
3. Lot of the Repro have so much damaged you as Inspector should check gas lines.
4. This a very simple task in you home inspection by getting a spray bottle and putting little soap in it with water and spray the lines.
Just like other day I was check mobile in a trailer park and all I could spell is natural gas. Thank god no around me had a cigarette. This could have been just like San Fransisco. I called Southwest gas company an they had some their to fix the gas flex line from the hard pipe to the trailer. They show in about 15 minutes from the time I called. This was awesome how quickly they show up. I was truly amazed.
As a Realtor or Home Inspector please take the time to do this kind of stuff.
