hi...all you have to do to reset the pressure value on the back of the outlet (water coming out against the wall ?) is push the nylon ball back into place using a small/medium sized allan key. push hard enough and the ball should click back into place. test to see if water stopped from pressure outlet..if not try to push in a little harder. mine is a 10.5 deluxe...done twice over 2 years ..no probs...
