Toilets in Centennial homes from the 1980s have been running through multiple fill valve and flapper generations over 30 to 40 years of service. The internal components wear out and are replaced, but the toilet itself eventually reaches the point where the porcelain cracks, the seat and bowl connection loosens, or the fixture simply looks and performs like a 40-year-old toilet. WireNut handles the full range of toilet service in Centennial, from a running toilet repair to a complete replacement with a new high-efficiency fixture.

Toilet repairs that reveal a clog in the drain line rather than a fixture issue connect to our drain cleaning service. For complete bathroom plumbing updates that include toilet replacement, our kitchen and bath plumbing team handles the broader scope. See all Centennial plumbing services.

• Running toilet repair to stop continuous water flow from a worn flapper, failed fill valve, or float adjustment issue that is wasting water and inflating water bills.
• Phantom flush repair for toilets that periodically cycle on their own without being flushed, usually caused by a worn flapper that allows slow water loss from the tank.
• Clogged toilet clearing for toilet clogs that cannot be resolved with a plunger and require a toilet auger or removal of the toilet to access the blockage.
• Toilet wax ring replacement for toilets that are rocking, leaking at the base, or allowing sewer odor into the bathroom from a failed wax seal.
• Toilet replacement and installation for older fixtures being upgraded to modern low-flow models or for toilets that have cracked or are beyond repair.

Here are the toilet repair and installation calls our Centennial plumbers handle most often.

How Much Water Is a Running Toilet Wasting in My Centennial Home?

A toilet with a failed flapper that allows continuous water flow from the tank to the bowl can waste 200 gallons per day or more without producing an obvious sound. The toilet appears to flush and fill normally but the flapper is allowing a slow, continuous trickle that runs the fill valve nearly continuously to keep up. In Centennial where water costs have increased meaningfully, a running toilet can add $30 to $60 or more per month to a water bill depending on the severity of the leak.

The toilet dye test is the simplest way to check for a flapper leak. Put a few drops of food coloring in the toilet tank and wait 15 minutes without flushing. If the color appears in the bowl, the flapper is leaking and should be replaced. A flapper replacement is typically a simple and inexpensive repair. WireNut can handle it as a standalone service call or as part of a broader toilet tune-up.

When Should I Replace a Toilet Instead of Repairing It in Centennial?

Toilet replacement makes the most sense when the toilet is over 25 years old and has needed multiple internal component replacements, when the porcelain shows cracks at the base or tank, when the toilet rocks because the floor flange is corroded or damaged, or when a homeowner wants to upgrade to a modern low-flow toilet that uses 1.28 gallons per flush instead of the 3.5 to 7 gallons used by pre-1994 toilets. Centennial homes with original toilets from the 1980s are almost certainly running on very inefficient fixtures. The water savings from a modern low-flow toilet in a high-use bathroom can be meaningful over time.

WireNut gives you a repair estimate and an honest opinion on whether replacement makes more sense given the toilet’s age and condition. You get both options and decide.
