I have a 52gal stainless steel Westinghouse 4500 watt electric water heater that has developed a leak around both the upper and lower heating elements. It appears to be leaking from the joint between the tank and the female connector where the heating element goes in. The heating element gasket doesn't appear to be the cause. Please see the attached picture. Any thoughts? Does it appear to be fixable or manufacturer defect? I appreciate everyone's help in advance.
