Fill and flush diagnosis
Fill valve, flush valve, and flapper are checked in sequence, so a running toilet is traced to its part, not guessed.
A toilet that runs, rocks, leaks at its base, or flushes weakly is usually failing at one part: a fill valve, a flush valve, a flapper, a seal, or a flange.

Toilet repair covers fill and flush parts, flappers and seals, supply valves, and the base seal and flange. The diagnosis separates a tank fault from a base fault, because a running toilet and a leaking base are different jobs, even though both involve water where it should not be.
Hard water at about 180-190 mg/L in Cerritos commonly affects fill valves and flappers, which scale and wear, and older bathrooms commonly have flanges that have been sealed over more than once. A repair visit therefore checks tank parts, base seal, and flange together, so a tank repair is not handed over while the base is still leaking.
A toilet repair visit is a tank-and-base diagnosis. Both are checked, because a toilet has two places to fail, and fixing one while missing the other leaves the problem in place.
Fill valve, flush valve, and flapper are checked in sequence, so a running toilet is traced to its part, not guessed.
The base seal and flange are checked, because a leak at the base tracks water into the floor and, upstairs, into the room below.
The supply valve is checked while the tank is open, so a weeping valve is not left to fail next.
Flush power is assessed against the drain and the toilet's own parts, so a weak flush is not blamed on the wrong part.
Flush, fill, and shut-off are tested together, and the base is checked for leaks, before the visit ends.

Commonly a fill, flush, or flapper part that no longer seals, often with scale from hard water contributing. The tank parts are checked in sequence to find which part has failed.
Sometimes, but rocking can also point to a damaged flange or a soft floor beneath the seal. The base, seal, and flange are checked, because tightening bolts over a damaged flange hides the problem.
When the failed part is isolated and the toilet body, flange, and floor are sound. A cracked body, damaged flange, or soft floor points the discussion to a wider job.
Yes. Water tracking under a base seal soaks a floor and, upstairs, a ceiling below. A base leak is checked promptly, and the seal and flange are repaired rather than left to dry on their own.
