How to properly flush a hydronic system? Mike Holzworth
What is the correct way to flush a new hydronic boiler system (boiler, pumps, piping & terminal equipment. What chemicals should be used (I heard some are actually worse that the stuff your trying to get out of the piping)? How long do you circulate it in the system. Do you need to flush it with clean water after this cleaning?
