A Fresh Flush: Guest Bathroom Toilet Tune-Up in Knoxville

Plumbing | Knoxville | Plumbing in Knoxville

Customer’s Wednesday Morning Surprise

One Wednesday morning, a homeowner in Knoxville discovered their guest bathroom toilet wouldn’t stop running after each flush. That constant trickle not only created an annoying noise but also led to wasted water. Concerned about both the sound and the rising utility bill, they called HEP for a solution.

How It Was Solved

A HEP technician arrived promptly to inspect the problem. Inside the tank, several key parts—the fill valve, flush valve, and rubber flapper—had worn out and no longer sealed properly. The technician removed the old components and installed brand-new replacements:

  • A fill valve to control water levels
  • A flush valve for a smooth, powerful flush
  • A sturdy flapper to seal the tank when it refills

After reassembly, a quick leak test confirmed the fix. While on site, the technician also checked the upstairs master bathroom toilet to make sure it was leak-free.

Notice how the parts fit together without gaps or misalignment. Proper installation keeps water where it belongs—inside the tank.

Simple Tips to Keep Your Toilet Happy

  1. Listen for Hidden Leaks
    A faint hiss or trickle after flushing usually means the tank isn’t sealing. Catching it early prevents larger issues.

  2. Inspect the Tank Internals
    Every few months, lift the lid and look for worn or corroded components.

    If you spot cracked plastic or mineral buildup, plan for a part replacement.

  3. Use the Food-Color Test
    Drop a little food coloring into the tank, wait 10–15 minutes without flushing, and check the bowl. If color seeps through, the flapper or seals need attention.

  4. Know When to Call In Experts
    Swapping a flapper is a straightforward DIY task, but a full tank rebuild takes skill. If you’re unsure or the problem persists, a HEP technician can ensure the job is done right.
