Most toilet trouble traces back to one of a few replaceable parts: the flapper, the fill valve, the flush valve, the wax ring or the mounting bolts. That means a toilet can almost always be repaired rather than replaced. Call the number on this page to be connected with a local plumber in Durham.

Match the symptom to the part
| What you notice | Usual cause |
|---|---|
| Tank refills by itself between flushes | Flapper no longer seals |
| Water spilling into the overflow tube | Fill valve set too high or failing to shut off |
| Flush is weak or takes two tries | Low water level in the tank, a flapper closing early, or blocked rim jets |
| Wet floor around the base | Failed wax ring or loose closet bolts |
| Drips below the tank | Tank bolts, the supply line or a fine crack |
| Toilet rocks when you sit | Loose bolts, a broken flange or a weak subfloor |
A silent leak test
A flapper that has hardened can let water slip into the bowl without making any noise. To check, put a few drops of food coloring in the tank, wait about ten minutes without flushing, and look at the bowl. Any tint means the tank is leaking and the flapper probably needs replacing.
What Durham's sewer can take
The City of Durham says only water, human waste and toilet paper are permitted into its sewer system. Wipes, even ones sold as flushable, paper towels and hygiene products are common reasons a toilet clogs repeatedly, and they can catch in the line beyond it.
Clogs that keep coming back
If plunging clears the bowl only for a day, or the tub gurgles or rises when the toilet flushes, the blockage is probably in the building drain or sewer service line rather than the toilet itself. Stop flushing and have a plumber clear the line and, if needed, run a camera to see what is causing it.
Lifting the toilet off the floor
Stopping a leak at the base means pulling the toilet and setting it on a new seal. While it is up, the plumber should look at the flange and the surrounding floor, since slow seepage can soften wood. That matters most in older houses; about 30% of Durham homes were built before 1980.
Fix or replace
Parts are inexpensive and easy to find, so repair is usually the sensible choice. A cracked tank or bowl is the main exception. If you are putting in a new toilet, ask whether a plumbing permit from Durham City-County Building & Safety applies, since its permits cover fixture replacements.
Cost factors
The part that failed, whether the toilet has to come up, the condition of the flange and floor, and whether a new fixture is involved all affect the price.
