Toilets
A worn flapper, a fill valve that will not shut off or a failed wax seal at the base can each keep a toilet running or leaking. Each part can be replaced on its own.
A toilet that runs all night, a faucet that drips into the sink, a shower that swings from hot to cold or a disposal that hums without turning wastes water or patience. Each one is repaired, or the fixture is replaced.
Below are the fixtures and parts a plumber can repair, and what the Texas permit rule and Garland’s own permit page say about plumbing permits for this kind of work.

A worn flapper, a fill valve that will not shut off or a failed wax seal at the base can each keep a toilet running or leaking. Each part can be replaced on its own.
A steady drip from the spout traces back to a cartridge, washer or O-ring that has worn thin, and a sideways spray to an aerator crusted with scale. When the body itself is cracked, a new faucet goes on.
A shower that scalds or runs cold when a toilet flushes can need a new cartridge or a pressure-balancing valve. The valve sits behind the wall, so the work is done through the trim plate or an access panel.
Hear a hum with no grinding? The disposal is jammed and can be freed. Water dripping from its underside means the unit has failed internally and needs replacing.
The state permit requirement for plumbing work in cities above 5,000 people leaves out repairing leaks and replacing lavatory or kitchen faucets, ballcocks or water control valves, garbage disposals and toilets. Garland’s Building Inspection page, however, lists plumbing systems and repairs among the projects that may need a permit and does not say how it treats a simple swap, so ask the department before counting on the state exception.
Moving a sink, adding a bathroom or relocating a shower is new plumbing rather than a swap, so it falls outside that list of exceptions. Describe the change when you call so the estimate covers it.
Slow drains under a fixture are a drain cleaning job, and water showing up under a vanity can need leak detection. Go back to the homepage to see every service.
