Vaillant Brass Diverter Valve 0020132682 for Ecotec Plus/Pro Boilers

This Vaillant brass diverter valve 0020132682 directs water flow between central heating and domestic hot water inside compatible ecoTEC boilers. If the valve sticks or wears, you may notice hot water going warm/cold, heating and hot water not switching properly, radiators warming when a tap runs, or inconsistent flow/temperature. Replacing the diverter valve with the correct part is a reliable fix that restores proper switching and helps reduce nuisance shutdowns.
