Toilet internals and seals
Flappers, fill valves, supply lines and the wax seal at the base each cause a different symptom. A rocking toilet gets checked at the flange rather than just tightened down.
A toilet that runs all night or a faucet that will not stop dripping is a small repair that quietly wastes a lot of water. Denver Urgent Plumber fixes the fixture, or tells you honestly when replacing it is the better spend.
These are the repairs people put off, and they add up on a bill faster than most owners expect. In older Denver homes the parts behind the wall matter as much as the fixture in front of it: a 1950s ranch in Lakewood or Wheat Ridge may still have original angle stops that will not close, and a bungalow with galvanized nipples can have a shutoff that fails the moment it is asked to do its job.

Small jobs still deserve a proper look at what is behind them. Denver Urgent Plumber checks the supply and the shutoff along with the fixture itself.

Kitchen, bath and shower valves are repaired with the correct cartridge or seat for the brand where parts are still made, and replaced where they are not.
A seized angle stop turns a five-minute repair into a whole-house shutdown. Replacing it is usually worth doing while the plumber is already there.
High incoming pressure wears out fixture parts early. If the house pressure is out of range, you are told, because otherwise the new cartridge goes the same way as the old one.
Repairing a good-quality fixture is usually the better value. Replacement makes more sense when parts are discontinued, the finish is failing or the fixture is being changed for other reasons anyway.
If the toilet is clogging rather than running, see drain cleaning. Water appearing near a fixture with no drip is a job for leak detection, and a hot side that never gets hot belongs on the water heater repair page.

Yes. A flapper that does not seal can pass a surprising amount of water every day, and it is usually one of the cheapest repairs on the list. Add it to another visit if you have one coming, or mention it when you book.
Either the cartridge was not the right one for the valve body, the seat is worn, or the house pressure is high enough to keep pushing past it. Denver Urgent Plumber checks pressure as part of the visit so the same part does not fail again in a few months.
You should be able to, using the angle stop on the wall behind it. If that valve will not turn or will not seal, close the main instead and mention the stuck shutoff when you call, because it usually gets replaced at the same visit. Our service process covers the rest.
