Repaired damage gas line going into the crawlspace of the home. Performed a leak test and found no issues in the new line. I did detect a small amount of gas by the meter on the top connections. I tighten and double checked, no leak detected at that time. Relit the water heater to the home. *the water heater is showing signs of leaks and the exhaust is back falling and not allowing the fumes to exit safely. Provided an estimate to replace and install the water heater up to plumbing code.
