Wow that is some serious cleaning for the bottles
With regard to the FV tap is it one of those that you can rotate the main body. If so do you completely disassemble it for cleaning i.e separate the two halves and the tap. I have found over time wort can get past the first seal and into the body which you cant clean out without full disassembly. When reassembling a smear of food grade silicone grease on the seals stops it happening in the future.
A friend had a series of infections from his tap as he hadn't taken it apart and just assumed running cleaner through it was sufficient.
