Finding out which part failed
A running toilet can be the flapper, the fill valve or the overflow height. Each is a different repair, and replacing the wrong one leaves you with the same noise tomorrow.
Running toilets, dripping faucets, a wobbling bowl and leaks under the vanity. San Marcos Emergency Plumber repairs the fixtures you use every day, and replaces them when the parts are no longer worth chasing.
Hard water is the common thread. Mineral builds on flush valve seals, faucet cartridges and aerator screens, which is why fixtures in this area often need attention sooner than the manufacturer suggests. A tap with weak flow and no other symptoms is frequently just a blocked aerator.

Not every visit needs every item below. San Marcos Emergency Plumber separates the repair you called about from anything optional, and the quote shows both.

Angle stops, braided supply lines and mixing cartridges are checked while the fixture is apart. An old shutoff that will not close is a problem you want found now, not during the next emergency.
A rocking toilet usually means a failed wax seal or a damaged flange. It is reset on a fresh seal and shimmed level, because a bowl that moves will leak again.
Repair is nearly always the cheaper answer while parts are still available for the model. Replacement starts to make sense on a badly scaled fixture, a discontinued cartridge or a toilet that has been rebuilt more than once already.
If you own or manage a rental property, it is worth having every toilet and angle stop checked in one visit rather than call-by-call. Heavy shared use in student housing wears fill valves and flappers quickly, and a running toilet on an unattended unit runs up a bill fast.
Related work: drain cleaning when the fixture is slow as well as leaking, leak detection when the damp does not match the fixture, and water heater repair versus replacement if the hot side is the real complaint. Request a visit and describe what it is doing.
Which part failed, whether the model still has parts available and how many fixtures are involved. San Marcos Emergency Plumber checks the fixture, tells you the repair price and the replacement price, and lets you choose.
Yes. A toilet that refills every few minutes can waste more water than every other fixture in the house combined, and it shows up on the bill quickly. The parts involved are usually small ones.
Usually, yes — bring it out of the box before the visit so any missing parts or fitting mismatches are found early. San Marcos Emergency Plumber will tell you if it will not suit the rough-in. See how a visit works.
