Plumbing Level 2 – Cold Water Systems Practice Test

Before continuing work on cold water pipework with an unsafely supported cistern, which action should be taken?

Strengthen the cistern support Ignore the support issue and proceed Reduce pressure in the system Convert to an open vented system

Correct Answer:

Strengthen the cistern support

Explanation:

An unsafely supported cistern is a real safety risk. If the cistern isn’t properly supported, it can shift, detach, or crack under load or vibration, leading to leaks, water damage, or even injury to workers. Strengthening or re‑supporting the cistern eliminates that hazard, restoring stability so you can continue work safely. Ignoring the issue doesn’t remove the danger, reducing pressure doesn’t fix a structural fault, and changing the system’s type doesn’t address the immediate safety problem.
