A toilet that runs, rocks, leaks or clogs over and over is more than an annoyance. A running toilet can waste a surprising amount of water without making much noise, and a leak at the base can rot the floor underneath long before it shows.
A toilet that keeps running usually needs a new flapper or fill valve. Water at the base usually means the wax seal under the toilet has failed. A weak flush often comes from a low water level in the tank or mineral buildup in the rim holes. Repeated clogs can be the toilet or the drain line beyond it. Most toilet repairs are finished in one visit.
Not every toilet leak makes noise. Some tanks leak into the bowl so slowly that you never hear them refill.
The EPA’s WaterSense program suggests a simple check. Put a few drops of food coloring in the tank, wait 10 minutes without flushing, and look in the bowl. If color shows up, the tank is leaking. According to the EPA’s Fix a Leak Week guidance, a leaking toilet can waste about 200 gallons of water every day. Flush afterward so the dye does not stain the bowl.
| What is happening | Most likely cause | Typical fix |
|---|---|---|
| Runs constantly | A worn flapper, or a fill valve set too high | Replace the flapper, or adjust or replace the fill valve |
| Refills on its own now and then | A slow leak from the tank into the bowl | A new flapper or flush valve seal |
| Weak or incomplete flush | Low water level in the tank, or clogged rim jets | Adjust the fill level and clear the mineral buildup |
| Water on the floor at the base | A failed wax ring seal | Pull the toilet, replace the seal and reset it level |
| Rocks when you sit | Loose closet bolts or a damaged flange | Tighten or replace the bolts and repair the flange |
| Clogs again and again | An obstruction in the trap, or a problem in the drain line | Clear the toilet, then check the line beyond it |
Water escaping around the base of a toilet does not just sit on the floor. It soaks into the subfloor, and every flush adds a little more. Over time the wood softens, the toilet starts to rock, and the repair grows from a new wax ring into replacing part of the floor.
A rocking toilet also breaks the seal faster, so the two problems feed each other. If you notice either one, fix it before the floor gets involved.
A single clog is usually just the toilet. A toilet that clogs repeatedly, or a clog that shows up at the same time as slow drains elsewhere in the house, points further down the line. At that point the problem is the drain, not the fixture, and our drain and sewer line service is the right fix.
Toilet leaks are among the plumbing issues most likely to cause hidden damage, because a bathroom sits over the rest of the house. Water that gets past a failed seal runs through the subfloor into the ceiling below, or into a basement or crawl space. By the time a homeowner sees a stain downstairs, the leak has usually been going for a while.
That slow soaking causes structural damage to the wood around the drain and creates the damp conditions where mold growth starts. The EPA’s guidance on mold says wet materials should be dried within 24 to 48 hours, which is why a toilet that rocks or leaks at the base is a repair to schedule soon, not someday.
An overflowing toilet or a sewage backup is different. That is a job for an emergency plumber, and our plumbing technicians take those calls 24 hours a day, 7 days a week. Turn off the valve behind the toilet, keep people out of the water, and call.
Almost every part inside the tank can be replaced, so a sound toilet is usually worth repairing. Replacement makes more sense when the tank or bowl is cracked, when repairs keep stacking up, or when an older toilet uses far more water per flush than a modern one. If it is time for a new one, see what goes into a proper toilet installation.
A toilet looks simple, but a repair touches the supply line, the shutoff valve, the wax seal and the drain pipe beneath the floor. Getting any of those wrong turns a small fix into water damage.
Call or schedule online, and a technician will diagnose the problem before recommending a fix.
Republic homeowners often call about a toilet that keeps clogging, and sometimes the toilet is fine. In older homes especially, the real plumbing problem sits further down the line.
Our technicians clear blockages first, then use a camera inspection to see what caused them, so nobody recommends excavation or pipe repair on a guess. The toilet also gets an inspection for hidden leaks at the tank bolts and the base, and if the bathroom faucet drips, it can be fixed on the same trip. Catching these early can help prevent future backups and costly repairs.

That is called a phantom flush. Water is slowly leaking from the tank into the bowl until the level drops enough for the fill valve to top it up. A new flapper usually fixes it.
Usually not, but it is costly to leave. A toilet that is overflowing or leaking onto the floor should be shut off at the valve behind it right away.
Yes. A leak between the tank and bowl stays inside the toilet, and a failed wax seal can leak into the subfloor before any water appears on the surface.
Turn the valve behind the toilet clockwise to shut off the water. If the valve will not turn, lift the tank lid and raise the float to stop the fill, then shut off the main.
A hissing sound usually comes from the fill valve, either because it is not shutting off fully or because water is slowly leaking out of the tank and the valve keeps topping it up.
