Toilet Problems Have You Frustrated? How to Troubleshoot Common Issues


Toilet Problems Have You Frustrated? How to Troubleshoot Common IssuesWhile troubleshooting toilet problems is definitely doable yourself, making the necessary repairs may require the skilled services of a plumber. However, it never hurts to take a look so you’ll know what you’re talking about when you describe the problem. You might get lucky and find something simple to repair on your own, too. Here are some of the common issues that might have you troubleshooting toilet problems:

Toilet Runs Non-Stop

Possible causes include:

  • Rubber flapper valve has deteriorated.
  • Kinked lift chain is preventing the flapper valve from closing.
  • Float ball is binding against the side of the tank.
  • Defective fill valve isn’t shutting off.
  • Fill valve water level adjustment is too high, sending water down the overflow tube.

Toilet Flushes by Itself

Possible causes include:

  • Leaky flapper valve is letting water gradually seep from the tank into the bowl, causing the fill valve to actuate periodically.
  • Defective fill valve.

Weak Flushing Action

Possible causes include:

  • Defective or maladjusted fill valve isn’t refilling the tank to the proper water level so flush volume is insufficient.
  • Lift chain isn’t pulling flapper valve open far enough due to excess slack in chain. Flapper should open sufficiently to empty at least 80 percent of the tank volume.

Very Slow Tank Refill

Possible causes include:

  • The water supply valve on the wall behind the toilet may not be fully open.
  • Mineral deposits inside the valve or the water supply line may be restricting water pressure.

Gurgling Sounds or Bubbles in the Bowl

Possible causes include:

  • An obstructed air vent. Excess air pressure inside the sewer pipes may escape up through the toilet bowl if one of the household sewer air vents is obstructed.

Water on Bathroom Floor Near the Toilet

Possible causes include:

  • Connection between the water supply line and the toilet fill valve is leaking.
  • Cracked toilet tank or bowl.
  • Wax seal ring in the base of the toilet is defective.

Troubleshooting toilet problems may only identify what's wrong. Competent service is usually required to fix it. In Calgary, contact the plumbing pros at Arpi's Industries, Ltd.
