Customer had a fireplace company come and run a new line to a new fireplace. Fireplace company had left a supply line and gauge. Pressurized the section of line that inspector requested to be pressure tested to 15 psi (picture with pressure reading attached). Line will sit for 24 hours until inspection. If any leaks are found to be on the system by the inspector, fireplace company will need to find and repair leaking section of pipe.
