About Boiler Drains
Although commonly referred to as “boiler” drain valves, these valves are suitable for other equipment types and a wide range of applications. Boiler drains have a design similar to that of a sillcock and are more compact to allow for installation in concealed locations. Since most of these valves installed at a lowest level in the system, they have an angle spout, which allows for easier connection of a drain hose.
