How can i fix my Vaillant Turbomax vuw Boiler?
Hi i have a Vaillent Turbomax VUW GB 282-5, everytime i turn the hot water tap on or my central heating it makes a horrible noise like an areoplane is trying to take off. We have had the pump and the diverter valve replaced but is still making the noise. The last person to come out turned off the service valves why he worked on the boiler when he turned tham back on they started leaking, the company could not get any new valves but have filled it with sealent they are now telling me that thi is why the boiler is makng the noise and that they need replacing.
