disconnect the filling loop first

kev i put the filling loop to off,and drained water from radiator pressure went down to normal levels but when i run water pressure goes back up .radiator light comes on but water light doesnt.is The filling loop is a black lever under system which lets water in isnt it.thanks for help

yes but it's not uknown for the valve to pass

hence remove the loop pipe

silver pipe it screws on both ends
