Have had a semi-automatic line cleaning system fitted for a while now and have experienced many problems primarily caused by it`s cleaning cycle only lasting approx. 3 minutes. Can you tell me are there any circumstances under which this would seem like optimum cleaning procedure when it clearly states on the line cleaning fluid container ,an immersion time of 15-25 minutes. Tech services for all leading breweries have attended when i have been experiencing problems with fobbing,smell etc. and have declared (un-officialy) that the system is "not fit for purpose" or "sh**e!!! Has anyone else had the same probs? The company(Beer Piper) who rent me the system behave like "Nazis" when it is suggested their equipment might be at fault.
