Pipe Up an Open-Vented Hot Water System

The cold draw-offs to the taps are already fitted — your job is the hot side plus the two cistern connections: the cold supply into the cistern and the cold feed down to the cylinder, then the hot distribution and the open vent. Tap a component to zoom in, tap the connection, then the destination. Name each pipe; choose a size where asked.

🎯 To pass: build the whole system, then Check it — you need it 100% correct on your first complete Check. You can keep fixing to learn, but a pass is only logged for a clean first attempt — hit Reset to try again.
