01
What affects service life?
System type, water quality, installation, maintenance and usage all affect how long a hot water unit remains reliable. Age alone does not confirm that replacement is required.
02
Signs a system needs attention
Leaks, rusty water, inconsistent temperature, unusual noise and repeated faults warrant assessment. A plumber can help distinguish a repairable component fault from broader deterioration.
03
Repair or replacement
Compare the confirmed fault, system condition, repair value and ongoing reliability before deciding. A sound diagnosis is more useful than a generic age rule.

Frequently asked questions
Should an old hot water system always be replaced?+
No. Condition and the confirmed fault matter. Some issues are repairable, while leaking or deteriorated units may be poor repair candidates.
