Air drain valve and A water heater drain valve

An air drain valve allows the removal of potentially harmful condensates such as water, oil or rust. These contaminates can build up over time and can lead to airline obstruction or weakening of the storage tank. Excess water in the air drain valve system could cause the interior of steel storage tanks to rust as w. Automatic air drain valves are commonly used on large trucks with air braking systems to drain oil and water that could potentially cause the brakes to fail. A water heater drain valve is used to periodically drain water and remove contaminates from hot water heaters. Over time, mineral scale consisting of calcium or other minerals can form on the inside of water heaters. Sediments such as dirt or sand can build up in the bottom of the tank as well. This lowers the heating efficiency of the heating elements and can eventually lead to permanent damage if left unchecked. Periodically opening the drain valve can allow most of these contaminates to drain from the hot water heater.
