Grant Vortex Mk2 frozen/blocked condensate water pipe


My one-year-old Grant Vortex Mk2 boiler’s condensate water pipe is chocked. I doubt that it is due to cold weather or some blockage. I have restarted it but did not work. Please help.

Thank you so much


Hi Frank, most of the boiler owners face this issue during extreme weather conditions. Well, do not take tension as you can try different things to solve this matter at home. Firstly, you have to locate a blockage in the condensate pipe. After locating it, thaw the blocked or frozen pipe by simply putting the hot water. However, never use the boiling water, as it will damage the pipe. Lastly, restart or reset your boiler by pressing a button.
