How often should I inspect sink & vanity?
Inspect sink & vanity at the manufacturer or authority interval, after severe weather or unusual operation, and whenever a documented condition changes.
What this means
Sink & vanity covers faucets, traps, pop-up drains, supply valves, and cabinets. Relevant observations include No hot water at this sink, Sink drain stopper does not work, Trap is leaking, Vanity cabinet is damp, Sink smells like sewer. The correct response depends on age, design, climate, usage, installation, recent work, and the exact manufacturer instructions; these observations narrow next steps but do not prove a failed part.
Safe checks
- Use the exact manual, warranty, local authority, and service history to set the interval for sink & vanity.
- Add a check after severe weather, renovation, long vacancy, or unusual operation.
- Shorten the interval when a condition is changing or has recurred.
Stop and get help if
- Stop for sewage, rapidly spreading water, a bulging surface, or water near electricity.
- Do not force a seized valve or open a concealed supply or drain.
Which professional to call
Use a qualified plumber when the condition exceeds safe user access or the visible checks do not explain it.
