Toilet repair

A toilet that runs needs a new flapper or fill valve. One that rocks or leaks at the base needs a new wax ring and possibly a flange repair. A toilet that clogs every week may have a partial blockage in the drain line or a low-flow design that can't keep up.

About toilet repair

A running toilet can waste far more water than most people expect, enough to show on a monthly bill. A leak at the base is worse: it soaks the subfloor quietly, and in a second-floor bathroom it eventually shows up in the ceiling below.

Toilet repairs are usually quick. The plumber's job is to tell a simple part swap from a damaged flange, a cracked tank or a drain problem.

What affects the cost

Every job is priced by the plumber after they see it. These are the things that move the price most. Ask for the price before work starts.

  • Part replacement or full toilet replacement
  • Flange or subfloor damage
  • Clog beyond the toilet
  • Toilet style and height

Before the plumber arrives

Safe to do

  • • Use a flange plunger on a clog
  • • Turn the supply valve off behind the toilet

Stop and call

  • • Stop if the floor is soft around the toilet
  • • Don't keep flushing a toilet that is about to overflow

Toilet repair questions

Why does my toilet run every few minutes?

That's a slow leak from tank to bowl, usually a worn flapper. Put a few drops of food coloring in the tank; if color reaches the bowl without flushing, the flapper needs replacing.

Why does my toilet keep clogging?

A partial blockage further down the drain, a clogged trap or rim jets, or an older low-flow design that can't clear waste. A closet auger and a look at the drain line usually tell which.

How do I fix a toilet that rocks?

Tighten the closet bolts gently; if it still rocks or leaks, the wax ring and possibly the flange need replacing. Shims can level it on an uneven floor.

Should I repair or replace an old toilet?

Replace a cracked toilet or one with an obsolete flush system. Otherwise, internal parts are cheap and repair usually makes sense.

Is a leaking toilet base an emergency?

Not usually, but stop using it and fix it soon. Water leaking at the base soaks the subfloor and, on upper floors, the ceiling below.

What toilet should I buy in Colorado?

Colorado law requires new toilets sold in the state to be WaterSense-labeled. Compare flush performance ratings, height and bowl shape.
