Valve and trap check
Supply valves and the trap are checked before the new unit is set, so a seized valve or failing trap is dealt with as part of the job.

Sink installation means removing the old unit, checking supply valves, drain, and trap beneath it, setting the new unit, connecting faucet and drain, sealing the rim, and testing fill and drainage. The supply and drain check is part of the job, because a new sink on seized valves or a failing trap is only half a job.
Kitchen sinks in Cerritos commonly see grease and food waste, and bathroom sinks commonly see hair and soap, so the drain beneath a new sink deserves the same attention as the basin above it. Older homes commonly have valves and traps that have not been touched in years, and hard water at about 180-190 mg/L leaves scale in valves and aerators. An installation visit therefore checks valves, trap, and drain before the new unit is set.
A sink installation is a counter, supply, and drain job as much as a basin job. The basin is the visible part; the valves and trap underneath decide whether it lasts.
Supply valves and the trap are checked before the new unit is set, so a seized valve or failing trap is dealt with as part of the job.
The new sink is sealed to the counter and set level, so water does not track under the rim.
The faucet is connected and the drain and trap are fitted, with both checked for leaks under pressure and flow.
Fill, overflow where fitted, and drainage are tested together, so the sink works as a system before the visit ends.
The old sink is removed, the area is wiped down, and the new sink's operation is explained.
Where Sink Installation work reveals a neighbouring problem, it is pointed out plainly, so a later visit starts from a clear record rather than a surprise.

A new counter or remodelled kitchen or bathroom is the natural time to fit a new sink, with valves, trap, and drain checked at the same visit.

Because a seized valve or failing trap fitted under a new sink will fail soon after, and will be harder to reach once the sink is sealed in. Those parts are checked and dealt with as part of the installation.
By testing fill and drainage together, and by checking every connection beneath the sink for leaks. A sink that fills but drains slowly, or drains but leaks at its trap, has not been tested as a system.
A like-for-like sink swap does not usually need a permit; re-pipe and water heater work do. Where a job goes beyond a swap, for example relocating supply or drain, the Cerritos Permit Hub at permits.cerritos.gov is the front door to check.
