I moved a water heater about 2 feet from where it was .Now i am getting cross over in the kitchen not up stairs . I also rough in a new bathroom in the basement about 3 feet from the water heater . They never had this problem before ,can it be the old hot water heater(about 30 years old) is to high temperature .and can be crossing over . or do i need to put a check valve on the line , also the water is about 3 feet away from the hw .The inspector will inspect the bathroom not the wh .next week sometime
