Adding corrosion inhibitor to CH system.
Last time I did this I partially drained the system and added corrosion inhibitor via the expansion tank.
Do I really have to drain the system at all to add it?
Can I just take a volume if water, equivalent to the fresh inhibitor that I am going to add, out of the tank and add it that way?
Am I wrong to assume that it will eventually work its was around the entire system from there?
Ta in advance.
