A malfunctioning toilet can be frustrating and inconvenient, especially if it leads to wasted water or potential damage to your home. While some toilet issues can be resolved with simple fixes, others may require professional assistance.

If you’re experiencing toilet troubles in Bainbridge Island, WA, Swift Plumbing & Heating is here to help. Below are some common toilet problems and how to address them safely.

Toilet Won’t Stop Running

A continuously running toilet can waste hundreds of gallons of water per day, increasing your water bill.

Common causes:

  • Faulty flapper valve that doesn’t seal properly
  • Fill valve issues causing constant refilling
  • High float level, leading to excessive water filling

How to fix it:

  • Check the flapper valve for wear and replace it if necessary.
  • Adjust the float level to prevent excessive water filling.
  • If the problem persists, contact a professional plumber to diagnose and fix the issue.

Weak or Partial Flush

If your toilet isn’t flushing completely, it may be due to clogged rim holes, a low water level, or a flapper issue.

How to fix it:

  • Check the water level in the tank and adjust the fill valve if needed.
  • Use a thin wire or brush to clear mineral buildup from the flush holes.
  • Replace the flapper if it’s not sealing properly.

Clogged Toilet

A clog is one of the most common toilet problems, often caused by excessive toilet paper, non-flushable items, or buildup in the pipes.

How to fix it:

  • Use a plunger to create suction and dislodge the clog.
  • Try a plumbing auger (toilet snake) if plunging doesn’t work.
  • If clogs are frequent, a professional drain cleaning service may be needed to remove deeper blockages.

Leaking Toilet Base

If you notice water pooling around the base of your toilet, it could indicate a worn-out wax ring or loose bolts.

How to fix it:

  • Tighten the bolts securing the toilet to the floor.
  • If the leak persists, the wax ring may need replacement.
  • Professional assistance is recommended to ensure a proper seal and prevent further leaks.

Toilet Tank Fills Slowly

A slow-filling toilet tank can be caused by low water pressure, a clogged inlet valve, or a faulty fill valve.

How to fix it:

  • Check the water supply valve to ensure it is fully open.
  • Clean or replace the fill valve if it is clogged with debris.
  • If water pressure is low, consult a plumber to check for pipe blockages or municipal water supply issues.

Phantom Flushing (Toilet Flushes on Its Own)

If your toilet flushes unexpectedly without anyone using it, you may have a leaky flapper or a defective fill valve.

How to fix it:

  • Inspect the flapper for wear and replace it if needed.
  • Check the fill valve for slow leaks and replace if necessary.
  • A professional plumber can perform a full toilet inspection if the issue persists.

Cracked Toilet Tank or Bowl

A cracked toilet can cause leaks and structural issues, leading to water damage.

How to fix it:

  • Minor cracks may be sealed temporarily with waterproof epoxy, but this is not a long-term fix.
  • For significant cracks, a toilet replacement is recommended.
  • Swift Plumbing & Heating can help with expert toilet installation services.

When to Call a Professional Plumber

While some toilet issues can be fixed with DIY methods, others require expert attention. Contact a professional if:

  • Your toilet is leaking and causing water damage.
  • You experience frequent clogs despite proper use.
  • The flush mechanism doesn’t work properly after multiple repairs.
  • You notice a sudden increase in your water bill due to a running toilet.

Preventative Maintenance Tips

Avoid costly toilet repairs by following these maintenance steps:

  • Inspect the flapper and fill valve regularly for wear and leaks.
  • Never flush non-flushable items such as wipes, paper towels, or feminine hygiene products.
  • Use a toilet-friendly cleaner to prevent mineral buildup in flush holes.
  • Schedule regular plumbing checkups with a professional to catch issues early.

FAQs About Toilet Repairs

Why does my toilet keep running after I flush?
A worn-out flapper or improperly adjusted float can cause a running toilet. Replacing the flapper or adjusting the float level should resolve the issue.

Can I use chemical drain cleaners for toilet clogs?
It’s not recommended. Harsh chemicals can damage your pipes and may not effectively clear deep clogs. A plunger or plumbing auger is a safer solution.

How long does a toilet last before needing replacement?
Most toilets last 20 to 30 years, but frequent repairs or cracks may indicate it’s time for an upgrade.

What’s the best way to prevent toilet clogs?

  • Only flush toilet paper and human waste.
  • Use a moderate amount of toilet paper per flush.
  • Keep a trash bin nearby for non-flushable items.

Conclusion

Toilet issues can range from minor inconveniences to major plumbing emergencies. Knowing how to identify and fix common problems can save you time and money.
