Pipe Up the Cold — Combi System

The hot supply is already fitted for you — your job is the cold. 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.
