How often should I inspect sink & drain?
Inspect sink & drain at the manufacturer or authority interval, after severe weather or unusual operation, and whenever a documented condition changes.
What this means
Sink & drain covers drainage, faucet flow, leaks, traps, and supply. Relevant observations include Sink will not drain, Sink gurgles when dishwasher runs, Faucet has low pressure, Water leaks below the sink, No hot water at this faucet. 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 & drain.
- 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.
