When a tankless system was added, the gas line often wasn't upgraded, causing pressure drops and ignition problems. We test static and dynamic gas pressure with a manometer. If the line is undersized, we explain your options and can upgrade the gas piping to meet the unit's requirements and California Plumbing Code.
