I never thought of that! (Oh gee thanks, another thing to worry about :lol:). I think this might be all my fault. In May I dragged out my immense and complicated system of hoses (each hose and connector numbered, with a corresponding map) , laid them all out, hooked them up, repaired leaks, bought new washers, etc. "There," I said out loud, "ready for a dry summer." Then the rains started.... Tell me, does anyone know...can hoses be damaged by mold?
