Low flow at one tap feels different from low flow throughout the house. Before deciding what needs repair, note where the change is happening and when it began.
One fixture or several?
If only one faucet has slowed, its aerator or fixture may be restricted. Check whether both hot and cold water are affected. If several taps changed together, the cause may be in the supply, a valve, a pressure-reducing device, or another part of the plumbing system.
If only hot water is affected, mention that when you call. It helps narrow the conversation toward the water heater and hot-water piping. A sudden change after work in the neighbourhood can also have a different cause from a gradual change over months.
Look for other signs
Check for visible leaks, damp patches, a running toilet, or an unexpectedly high water bill. If pressure rises and falls, note whether it happens when other fixtures run. Ask a neighbour whether they have noticed a similar change if you suspect an area-wide supply issue.
Avoid adjusting a pressure-reducing valve or opening fittings without knowing how the system is configured. Too much pressure can stress fixtures and piping; too little can be a symptom rather than the main problem.
