Gas line to pool heater was making meter make weird noises. After evaluating the meter all the way to the pool heater found that the line is ran and three-quarter track pipe and for customer the line needs to be at least an inch and a quarter when it’s running at the link that’s at. Customers previous line was ran at 162 feet and three-quarter gave customer estimate to run new gas line from meter all the way to pool heater customer customer approved estimate. Installed new inch and a quarter. Gas line tested system. Unit is working and fired up with no leaks or issues. Meter is also not making any noise. Had pool heater fired up for 5 to 10 minutes to make sure nothing happened. System is running with no issues.
