Ok this thread brought me out of lurker status (my first official reply to a thread). I will confess to my failed attempt at adding CYA by sock. I had my sock set up on a string near the discharge at the deep end. I had just started the maiden voyage of my new Dolphin M400 (which I purchased due to reviews here at TFP). I decided to squeeze the sock to speed CYA delivery, and that's where things went wrong. I ended up dropping the sock into the pool, no big deal right.
Wrong, here comes my new M400 on its way to "clean" the Sock! Quick dash to the power button for a quick shutdown.
just had to reply, I feel better about my own screw up knowing I'm not the only one these things happen to.
