Print the pressure-pattern worksheet
Low pressure is best sorted by pattern: one fixture, hot-water only, the whole property, or a wider neighborhood issue. Check safe, visible conditions and official utility notices first. Do not adjust regulators, open meters, dismantle valves, or assume a leak based on pressure alone.
Pressure is not a diagnosis. Do not turn regulator screws, operate unknown curb stops, or work around electricity, gas, hot surfaces, flooding, or damaged components.
- Compare one fixture, hot-only, whole-property, and neighbor patterns.
- Remove and inspect a faucet aerator only when it is designed for normal homeowner cleaning.
- A closed local valve, fixture restriction, water-heater issue, private service problem, or utility event can look similar.
- Record timing and recent work before calling.
- Use the utility first when neighbors or notices show a wider issue.
Pressure pattern comparison
| Pattern | Safe observations | Professional question |
|---|---|---|
| One fixture | Hot/cold difference, nearby fixtures, visible aerator debris | Is the restriction at the fixture or branch? |
| Hot only | All hot fixtures, heater status, visible leaks or discharge | What part of the hot-water system was tested? |
| Whole property | Start time, all fixtures, recent work, notices, neighbors | Was the utility/private boundary and static/flow condition checked? |
| Intermittent | Time, irrigation, appliances, treatment cycles, demand | Which automatic or demand-related systems were ruled in or out? |
| Shared building | Units/floors affected, manager notices, common equipment | Who controls the shared supply and access? |
Observation and decision record
Use this sheet to organize facts and professional findings. It does not diagnose the property, assign responsibility, or replace current emergency, utility, legal, permit, or professional instructions.
