Common Toilet Problems We Fix
Don't ignore these issues—early repair prevents water damage and higher utility bills.
Running Toilet
A toilet that won't stop running wastes hundreds of gallons of water per day and drives up your utility bill. Usually caused by a faulty flapper or fill valve.
Weak or Incomplete Flush
If your toilet doesn't flush completely, it could be due to a clogged rim jet, low water level, or a failing flush valve that needs professional attention.
Fill Valve Issues
A noisy, slow-filling, or constantly running fill valve needs repair or replacement. This is one of the most common toilet problems we fix daily.
Leaking at the Base
Water pooling around the base of your toilet usually indicates a failed wax ring seal. This needs prompt repair to prevent floor and subfloor damage.
Blocked or Clogged Toilet
A blocked toilet that won't clear with a plunger needs a professional plumber. We use commercial-grade augers and hydro-jetting when needed.
Phantom Flushing
If your toilet seems to flush on its own or periodically refills, you likely have a slow leak from the tank to the bowl, typically caused by a worn flapper.

Get answers to common questions about toilet repair, installation, and costs.
How much does it cost to have a plumber fix a toilet?
Toilet repair costs vary based on the issue. Simple fixes like a flapper or fill valve replacement are typically very affordable. More complex repairs like replacing the flush valve or wax ring cost more. We provide free estimates with upfront pricing so you know exactly what to expect before any work begins.
Can a toilet fill valve be repaired?
In most cases, fixing a toilet fill valve means replacing it entirely rather than repairing the individual components. Fill valves are relatively inexpensive parts, and a full replacement ensures reliable operation. Our plumbers can diagnose the issue and complete the replacement in under an hour in most cases.
When should I replace my toilet?
Consider replacing your toilet if it's more than 20 years old, requires frequent repairs, has visible cracks in the porcelain, or uses more than 1.6 gallons per flush. Modern toilets use as little as 1.28 GPF and can save you significant money on water bills while performing better than older models.
How do you unclog a badly blocked toilet?
For severely blocked toilets, our plumbers use professional-grade closet augers (toilet snakes) that can reach deep into the drain line without scratching the porcelain. For blockages further in the line, we may use a drain camera to locate the obstruction and hydro-jetting equipment to clear it completely.
How long does toilet installation take?
A standard toilet replacement typically takes 1-2 hours, including removing the old toilet, inspecting the flange, replacing the wax ring, setting and leveling the new toilet, and connecting the water supply. If the flange needs repair or the flooring requires attention, it may take a bit longer.
