Really depends how you flush.
I did a microbore last week on a Wbosch cdi. Whole downstairs cold. Some never worked for months.
Drop down system tank fed.
Froze the FnR off. Cut into the system. Isolated the boiler from the flush (as create so much drag with the pump and diverter etc in the loop)
X800 norstrom heat and kamco mag.
Started downstairs loop 1st.
Then upstairs as a whole.
Then onto individual rads with a gentle vibration from a special drill I have. Then refit boiler run system up and drain down. Balance
Perfect result.
