Let's see who's paying attention on site... Customer says: ❌ Boiler is working❌ Hot water is working❌ Heating isn't coming on What's the FIRST thing you're checking? A) PCB B) Pump C) Heating controls D) Gas valve Drop your answer below before reading the comments 👇 The best engineers don't just know the answer... They know WHY. I'll reveal the answer later today.

I'll start... Too many apprentices focus on fitting. Not enough focus on fault finding. Anyone can learn how to fit a radiator, boiler, or pump. The real skill is walking into a property, understanding how the system works, and diagnosing the fault correctly. That's what separates average engineers from great engineers. If you're an apprentice, spend less time worrying about tools and more time learning: ✅ Heating controls✅ System layouts✅ Electrical testing✅ Fault finding processes Engineers: What's the biggest mistake you see apprentices making on site?
