Would you really water your plants with bleach or Jeyes?

I wouldn't. Has anyone actually been harmed by using water from a water butt (obviously you wouldn't drink it). I doubt it. Wash your hands after gardening and there should be no problem with hygiene. (Your chopping board has more bacteria than your toilet seat ... and probably more than your water butt)
