Getting to the Bottom of the Boiler Blowdown Procedure

Most boilers have a bottom drain line with two different valves: a knife valve and a gate valve. The optimum way to blowdown a boiler is to begin with the valves fully closed. Start by opening the knife valve, then open and close the gate valve. This should be done to both back and front valves if the boiler comes equipped.
