After inspection of system I found leak was on shut off valve feeding water heater. Appears the drain port for valve because loose, spraying water inside water heater closet in back of home. Tightened port to stop leak. Leak had caused water damage throughout flooring of home. Recommend performing proper mitigation to avoid further damage inside of home Hot and cold water lines inside water heater closet are poorly installed and are touching venting of water heater. This could eventually lead to the hot venting melting the plastic water lines, recommend reconfiguring the hot and cold water lines to prevent them from touching venting in water heater
