Hi there,
A few days ago the radiators went cold, so i bled them all with central heating turned off and turned a black knob on the pump to release pressure. but now it's happened again, doing what i did last time doesn't work. every so often i hear more bannging and water spots nto the tank upstaird from and overtank pump. but i have no heating! any recomendations how to get it working again?
