Toilet and Faucet Repair in the USA
Toilet and Faucet Repair starts with locating the water shutoff behind the fixture or under the sink. Our technicians turn that valve first to stop flow before they open the tank or remove the handle. They check the supply line for kinks or corrosion that let water seep onto the floor.
A running toilet often traces to a worn flapper or a fill valve that fails to seat. Faucets drip when the cartridge or washer inside the body wears from mineral buildup. We measure the stem height and thread pattern so the replacement part matches the existing fixture exactly. Homeowners anywhere in the USA can book toilet and faucet repair with Number One Plumber of Charlotte.

Warning Signs of Toilet and Faucet Problems
- Water pooling at the base of the toilet after each flush
- Handle on the faucet continues to drip after it is turned off
- Tank refills every few minutes even when not in use
- Hot water faucet delivers only a trickle after normal use
- Visible rust or green stains around the faucet collar
Common Causes of Leaks
Inside the toilet tank the flapper ages and no longer seals against the flush valve seat. Chain length can also shorten over time and pull the flapper open slightly. Mineral scale from hard water builds on the fill valve seal and prevents it from closing fully.
Faucet leaks usually begin at the cartridge or stem washer. The o-rings that sit above the cartridge crack when the handle is turned repeatedly. Aerators collect debris that restricts flow and forces water past the seals at the base.
What Technicians Inspect and Measure
Our technicians first check the angle stop valve under the sink or behind the toilet for corrosion on the compression nut. They measure static water pressure at the faucet with a gauge to confirm it stays below 80 psi. They also inspect the trap under the sink for standing water that hides a slow leak.
On the toilet they lift the tank lid and watch the water level against the overflow tube. They test the flapper by adding food coloring to the tank and checking the bowl after ten minutes. They measure the distance from the tank bottom to the seat to select the correct replacement flapper size.
Repair and Replacement Options
For toilets we can replace just the flapper and fill valve without removing the tank. When the flush valve itself is cracked we remove the tank and install a new flush valve kit that includes a new seal. Supply lines are swapped for braided stainless steel lines with 3/8 inch compression ends.
Faucet repair often means pulling the cartridge with a stem puller and installing an exact match from the same manufacturer. When the valve body is damaged beyond the cartridge we replace the entire faucet with a model that has the same hole spacing so no countertop work is needed.
What Homeowners Should Do First
Locate the shutoff valve and turn it clockwise until it stops. Place a towel or shallow pan under the fixture to catch any remaining water. Avoid using the fixture until a technician arrives so the leak does not worsen or damage the floor.
Note the brand and model number if visible on the fixture. Have the water heater turned down if the leak involves the hot side so scalding water does not reach the floor. Keep children and pets away from the wet area to prevent slips.
Toilet and Faucet Repair questions
Can a leaking toilet be fixed without replacing the whole unit?
Most toilet leaks come from the flapper, fill valve, or supply line connection. Our technicians replace these parts while the tank stays in place. Only a cracked tank or bowl requires full removal and a new fixture.
Why does my faucet drip only after the water has warmed up?
Hot water expands the cartridge or stem slightly and pushes past worn seals. We test both hot and cold sides with the water heater adjusted. The repair usually involves replacing the cartridge on the hot side only.
How do I know if the leak is at the shutoff valve or the fixture?
Turn the shutoff clockwise and watch if water still appears at the base. If flow stops the valve itself needs new packing or a full replacement. If water continues the problem is inside the toilet or faucet body.
What parts do you carry for older fixtures?
We stock universal flappers, fill valves, and cartridges that fit the most common toilet and faucet models. When the stem thread is unusual we measure it on site and order the exact match for the next visit.
