I have a Megaflo CL210HE which i have just reset the air gap on, as per the instructions on the stickked. But i did move a valve which i was not supposed to. It is a stop cock in the "Primary return" line. Should this valve normally be in the open or closed position?
All help wound be appretiated. Thanks,
