Commercial-Grade Toilet Rebuild Kit Service in Denver, CO

Worn Flapper or Warped Flush Valve

Possible causes: Chlorine and hard water minerals degrade rubber flappers, allowing tank water to leak constantly into the bowl.

What to check: Put food coloring in the tank; check if color appears in the bowl without flushing.

When to call a plumber: When water continuously trickles into the bowl and raises water bills.

Failed Wax Ring Seal Under Base

Possible causes: Rocking toilets or age degrade the wax gasket beneath the toilet, allowing wastewater to seep onto the subfloor.

What to check: Check for damp tile grout or spongy subflooring around the base.

When to call a plumber: When water appears on the floor after flushing or the toilet rocks.

Failing Fill Valve / Float Assembly

Possible causes: Internal diaphragms wear out, preventing the fill valve from shutting off and sending excess water down the overflow tube.

What to check: Remove tank lid and observe if water is pouring into the overflow pipe.

When to call a plumber: When the toilet hisses continuously and will not shut off.

Much of the Denver metro area sits above expansive clay soils that swell when wet and contract during dry spells, shifting underground water and sewer laterals and stressing foundation pipe penetrations.

Historic Housing Stock & Service Lines
