HONEYWELL 3 PORT VALVE

valve will be in position B marked on the brass body.
and the lever will have resistance on it .
 
So what position should the lever be in before anything is turned on? The MAN OPEN position or MANUAL position
 
you can't check them with the valve inplace only by checking the valves moving correctly.
but if the hw gets hot with only heating on and visa verser then the paddle is faulty and passing.
you can remove and fix it yourself don't have to be qualified.
