Than you for your suggestion but one of my problems is that I can.t get access to change the ball valve assembly as whover installed the tank put water pipes in front of the tank.There is very limited space to work and I am not able to see what I am doing so most of my adjustments are by touch.The space I have to work in is about the dimensions of the tank with about a foot above the tank and about 9 inches at the side.I have considered using a piece of wood under the ball valve arm and trying to bend the arm so that the tank does not fill up so much.Once again I appreciate your help.
Thank you and Merry Christmas
