The short answer

Most toilet repairs are inside the tank. A flapper that no longer seals, a fill valve that will not shut off or a chain that is the wrong length cause most running and weak-flush complaints. A toilet that rocks or leaks at the floor needs the bolts, wax ring and sometimes the flange under it repaired.

A running toilet can waste a lot of water without being obvious. The food-coloring test helps: add a few drops to the tank, wait 15 minutes without flushing and look for color in the bowl. If it shows, the flapper leaks. Scale from mineral-bearing water also builds up on the fill valve seat, which is one reason fill valves wear out in South Florida homes.

A toilet that rocks is not just annoying. Each movement breaks the wax seal a little more. The plumber pulls the toilet, checks the flange and the floor, sets a new wax ring or foam seal and bolts it down level. If the flange is broken or the floor soft, those get fixed first. If the porcelain is cracked, a new toilet is the real fix.

Common causes

  • Worn flapperRubber hardens and warps, letting water seep into the bowl so the tank refills every few minutes.
  • Failing fill valveMineral scale and wear stop the valve from shutting off cleanly, causing hissing or constant running.
  • Loose bolts or failed wax ringA rocking bowl breaks the seal underneath and can leak onto the floor.
  • Leaking tank bolts or gasketDrips under the tank where it meets the bowl point to the tank-to-bowl gasket or bolts.

What may be inspected

  • The flapper, chain, fill valve and float height inside the tank
  • The supply line and shut-off valve behind the toilet
  • Whether the bowl rocks, and the condition of the bolts and flange
  • The porcelain for hairline cracks in the tank or bowl

Questions about toilet repair

Water is leaking from the tank into the bowl, usually past a worn flapper, so the fill valve tops it up.

Low tank water level, a chain with too much slack, a partly clogged trap or scale in the rim holes.

Yes. Movement breaks the wax seal, which can leak under the floor covering.

Usually. New tank bolts and a tank-to-bowl gasket fix most leaks at that joint.

Often 5 to 10 years, less where scale builds up. Hissing or slow refilling are signs it is wearing out.

Add coloring to the tank, wait 15 minutes without flushing. Color in the bowl means the flapper leaks.

Many toilet makers advise against them, since the chemicals can wear flappers and seals faster.

When the porcelain is cracked, parts are unavailable or the toilet keeps clogging despite a clear drain.
