Hot Water, Pressure, and Leaks

Separate no hot water at all from hot water that runs out, check the energy source and reset safely, then stop at the gas, sealed, or wiring boundary.

Three goals pull the same dial in different directions. See what scald data, Legionella guidance, and energy advice each say, and how a mixing valve settles it.

Tell low pressure from low flow, separate one fixture from the whole house, and check aerators, valves, and the regulator before assuming a supply problem.

Run the ten-minute dye test, read what the sound tells you, and fix the flapper or fill valve before a silent leak quietly doubles a water bill.

Turn a suspicious water bill into evidence: run the meter test, isolate inside from outside at the main valve, and check the places leaks hide first.
