During inspection, if the cistern appears inadequately supported, which action is the correct initial remediation?

• A. Strengthen the cistern support
• B. Shut off the water supply and drain
• C. Install a new cistern cover
• D. Seal all joints

Answer: (A)

When a cistern isn’t properly supported, the first priority is to restore secure support. Stabilizing the tank prevents movement that can stress the connections, cause leaks, or even lead to the tank becoming detached from its mounting. Strengthening the cistern support directly addresses the root issue by ensuring the unit is firmly anchored to a solid surface and level, which is essential for safe operation and for any follow-up repairs.

Shutting off the water supply and draining might be wise safety steps before working on the cistern, but they do not fix the underlying problem of inadequate support. Installing a new cistern cover doesn’t address the stability of the tank, and sealing joints is about leaks at seals rather than how the cistern is held in place.
