The difference
What each option actually means
A repair can be sensible for a sound system with an available part; replacement may be more practical for major faults or poor condition.
The trade-offs
Age alone does not diagnose the problem, and an expensive repair is not always cost-effective.
How to decide
Consider fault severity, safety, parts, warranty, efficiency and expected remaining service life.
Before choosing
A plumber should assess suitability, condition, access and applicable requirements. Product or repair recommendations made without seeing the property are preliminary. Ask for the proposed scope, exclusions and relevant warranty details before approving the work.
