What to notice
Water coming in
Supply-side issues include faucet drips, under-sink connections, washing-machine hoses, low pressure, high pressure, and a main shutoff that may need attention. Identify whether the concern is on hot water, cold water, or both. A leak may travel along a pipe before it becomes visible. Record where it appears without assuming that the wettest spot is the source.
Water going out
Drain concerns range from a single slow sink to wastewater appearing at a low fixture. Repeatedly testing a drain can add to an overflow. When several fixtures are affected, tell the provider how the symptoms relate in time. A kitchen blockage, a shared branch issue, and a public sewer concern require different evidence and may involve different responsibilities.
Work that can wait for a plan
Fixture replacement, a remodel, seasonal preparation, and maintenance all benefit from written requirements. Keep model numbers, dimensions, photos of visible connections, and access restrictions together. Ask about permits before ordering equipment or closing walls. The calendar and completion checklist help you carry the same information from preparation through the end of a job.
