Inherited/bought a pool in 2006. It has a in floor Caretaker system that is not really working. How is this piece of equipment taken out or disconnected to the other equipment? The head has been replaced 2x. One of the floor values popped out and is stripped and no longer available. One doesn't pop up at all and the one in the shallower end pops up a little bit but does not rotate. I'm so done with this thing.
