I got caught out with doing what you suggest and had a nightmare with Vokera boilers now I PF every job and record the PH,TDS etc and only use X800 and X100.
BTW, WB tells you that the system has to be clean ,neutral PH ,low TDS etc etc but don't stipulate a PF as the be all to a clean system they leave that up to the installer.
