For an active leak, keep clear of electrical hazards and shut off water only if you know how to do so safely. If you smell gas, leave the area and follow emergency guidance rather than troubleshooting.
Start by identifying the symptom
Check another fixture to confirm the problem affects the whole home rather than one faucet or shower.
This is different from having none at all and may relate to capacity, settings, usage or a component fault.
Note whether this is constant or recent. That information helps a professional diagnose efficiently.
Water around the tank or connections changes the priority. Do not dismantle covers or work on gas/electrical components.
Who should you call?
Tank or plumbing is leakingA qualified plumber is usually the appropriate starting point.
Heating failure without a leakA plumber experienced with water heaters can diagnose most residential systems; some electrical or gas faults may require the corresponding licensed trade.
Replacement is suggestedAsk why repair is not practical and request the installed price, warranty and expected operating life.
Get the full picture first.
- What failed?
- Can it reasonably be repaired?
