I have a small inground pool with one jet. I have finished getting everything ready to open the pool, even filled it with water, but I cant seem to budge this silly jet plug! It is square, and the threading to screw it into the wall have some white tapey stuff on it...I tried cutting away and peeling the tapey stuff off, and tried using pliers to squeeze and turn it, but I don't think I am strong enough. Am I missing something? I am reaching from above it to try to unscrew it, the water is yucky and cold and I really don't want to have to get in it...any help is greatly appreciated!
