Water Heater Drain Valve Assembly
This is a picture of a Water Heater Drain Valve Assembly. It is a plastic valve that is opened and closed by turning the large plastic ring, left to open and right to close. There are several different types of drain valve assemblies and you should be able to identify each one. As home inspectors we do not operate these valves. Visually inspect for damage, corrosion, signs of previous leaking, or active leaking.
