Vaillant Turbomax Rebuild, Part1, How I rebuilt from scratch.

So this is a complete rebuild on the Best boiler vaillant ever built in my opinion. In this i strip it down from start to finish and start to rebuild.. In the upcoming video you will see tests performed and generally rebuild and possible faults rectified etc. It was all carried out .... now i need to work out whether its worth the next video.. If enough interest i will carry on... Ps any ideas for the complete unit ???
