Running toilets are usually a $20 fill valve or flapper. Not a full replacement.
Cracked tanks, broken flanges, and constant clogs usually mean it is time to replace.
We tell you the truth either way.

3. Common Problems, Signs & Symptoms
If you're seeing any of these, it's probably time to call.
Toilet runs constantly
Usually a worn flapper or fill valve — cheap parts, quick fix. Per the EPA, a leaking toilet can waste 200 gallons a day.
Water on the floor around the base
Almost always a failed wax ring. Left alone, water rots the subfloor and damages the ceiling below.
Toilet rocks when you sit down
A loose toilet means the wax seal is breaking. Tightening alone won't fix it — the seal needs to be replaced.
Constant clogs
Old low-flow toilets from the 1990s clog easily. Modern WaterSense models flush better and use less water.
Cracked tank or bowl
Cracks can't be repaired safely. Replacement is the only fix.
