Mud leg blow down

I was watching one of Dan’s videos, the part with the king valve on the take off and a shut off at the Hartford loop, then gets pressure up to ten pounds and I’m going to assume drain it at the 1.5 inch tapping, which I get but what about the mud leg I didn’t see about any pressure in there or if you just put a hose bib anywhere on the mud leg to get the mud out. Can anyone make it clearer on how to get the max mud out of the mud leg and should this be done one a month or season?

    It should be done at a Minimum once a season, or more often if boiler is neglected. This is NOT something for a DIYer of HO, or inexperienced person to do. Mad Dog

    A blow down at pressure like that should not be done by a novice or homeowner. It can be deadly if not done properly.
