Quick Fixes for Common Toilet Issues

May 07, 2024

Toilet problems are an unfortunate but common part of household maintenance. Whether it’s a continuous running sound, a weak flush, or a clog, many toilet issues can be solved with a few simple DIY fixes. Here’s a guide to troubleshooting and repairing the most common toilet problems without needing to call a plumber.


1. The Perpetual Running Toilet

A running toilet not only wastes water but can also increase your water bill significantly. This issue is usually caused by a faulty flapper or a problem with the fill valve. Here’s how you can fix it:


  • Check the flapper: Remove the tank lid and inspect the flapper, which is located at the bottom of the tank. If it’s not sealing properly, water will continue to flow from the tank into the bowl. Replace the flapper if it’s worn or damaged.
  • Adjust the float: Sometimes, the float is set too high, which prevents the fill valve from shutting off. Adjust the float lower so the water stops filling at about an inch below the overflow tube.

2. Weak or Incomplete Flush

A weak flush often indicates a clog in the jet holes around the rim of the toilet bowl. Here’s how to clear it up:

  • Clean the jet holes: Use a small piece of wire or a paperclip to poke each flush hole to clear out any debris. Be careful not to scratch the porcelain.
  • Check the tank water level: Make sure the water level in the tank is not too low. Adjust the float higher to increase the water level if necessary.

3. Toilet Clogs

Toilet clogs are probably the most dreaded toilet issue. However, they can usually be cleared with a good plunger or a plumber’s snake.

  • Use a plunger: Make sure to use a flange plunger designed for toilets. Create a good seal over the hole, and use a quick, sharp motion to dislodge the clog.
  • Use a plumber’s snake: If the plunger doesn’t work, try a plumber’s snake. Feed the snake into the toilet while turning it to break through the obstruction.

4. Leaks Around the Base

If you notice water pooling around the base of your toilet, the seal may be broken. Here’s what to do:

  • Tighten the bolts: Try tightening the bolts that secure the toilet to the floor. Be gentle to avoid cracking the porcelain.
  • Replace the wax ring: If tightening doesn’t help, you may need to replace the wax ring. Turn off the water, drain the tank and bowl, and remove the toilet. Replace the wax ring, and reinstall the toilet.

5. Toilet Won’t Stop Filling

If your toilet continues to fill without stopping, the fill valve likely needs to be adjusted or replaced.

  • Adjust or replace the fill valve: Check if the fill valve shuts off properly when lifted manually. If it doesn’t, adjust the fill valve according to the manufacturer’s instructions or replace it.

6. The Phantom Flush

Sometimes, you may hear the toilet begin to randomly refill as if it has been flushed. This phenomenon, often called a "phantom flush," is a sign of a slow leak from the tank into the bowl.

  • Replace the flapper or tank ball: A deteriorating flapper or tank ball can cause slow leaks. Inspect and replace if necessary.
