During a visual inspection of a cold water system before filling, which check is appropriate?

Explanation:
The essential check here is that the pipework is correctly jointed. Before filling, you want to visually confirm that all joints are sound, properly formed, aligned, and well supported, with no signs of leaks, gaps, or damage. This helps prevent leaks as soon as the system is pressurized. Painting fittings isn’t a relevant pre-fill check and could hide issues. The system should not be pressurized at this stage, since filling and pressure testing come after this visual check. The main stopcock should remain in place to allow isolation during filling and testing, so removing it would be inappropriate.
