how do i mount the float ball to the float ball fix frame? i need to separate the inlet fitting from the actual float ball valve so i can put the inlet through the hole on the mounting bracket and secure it with the nut. the float valve came brand new out of the box put together. i don't know if the inlet is screwed or glued to the float valve. it feels like its glued when i try to unscrew it. i don't want to break it since i just got it brand new yesterday.... you wont know what i am talking about if you don't have one of these valves from eshopps.
