Causes & Fixes for Hidden Toilet Leaks

One of the worst plumbing issues homeowners can face is a hidden toilet leak. These leaks can waste significant amounts of water, increase utility bills, and even damage a home. Identifying and fixing hidden toilet leaks can save you money and prevent potential water damage.

In this blog post, the plumbing experts at Action Plumbing, Heating, A/C & Electric explain some common causes and fixes of hidden toilet leaks so you can prevent catastrophic water damage from impacting your property.

5 Signs You Have a Hidden Toilet Leak

Not all leaks are immediately apparent, so it’s important to look out for signs of a hidden issue. Signs of hidden toilet leaks typically include:

• Unexplained increase in water bills: A sudden spike in your water bill without increased usage is a strong indication of a hidden toilet leak.
• Sound of running water: If you hear water running even when the toilet is not in use, it could signal a potential leak.
• Stains on the floor: Water stains around the base of your toilet suggest a leak that needs immediate attention.
• Mold or mildew: Persistent moisture from a hidden leak can lead to mold or mildew growth around the toilet area.
• Weak flush: A weakened flush could be caused by water leaking from the tank, preventing it from filling properly.

How To Confirm Your Toilet Is Leaking

If you suspect a hidden leak in your toilet but aren’t sure how to confirm it, there are a few steps you can take to determine whether a leak is hiding out in your bathroom. Here’s what to do:

1. Add a few drops of food coloring to your toilet tank.
2. Wait 15 to 20 minutes without flushing.
3. Check the toilet bowl for colored water. If the water in the bowl has changed color, you have a leak on your hands.

4 Common Causes of Leaky Toilets

Understanding what causes these issues can help you prevent the issue from occurring altogether. The following are just four of the most common culprits behind hidden leaks:

• Worn-out flappers: The flapper is a rubber valve at the bottom of the tank that stops water from flowing into the bowl. Over time, it can wear out or become misaligned, causing leaks.
• Faulty fill valve: The fill valve controls the water flow into the tank. If it’s not functioning properly, it can cause continuous water flow, leading to hidden leaks.
• Cracked tank or bowl: Cracks in the porcelain of the tank or bowl can cause water to seep out slowly, often unnoticed until significant damage has occurred.
• Loose tank bolts: The bolts securing the tank to the bowl can become loose, allowing water to leak at the connection point.

DIY Tips & Tricks for Toilet Leak Repair

Before you call in a professional for toilet leak repair services, there are a few DIY troubleshooting techniques you can try to resolve the issue on your own, including:

• Tighten floor connection bolts: Ensure the bolts connecting the toilet to the floor are tight and secure. If they’re loose, water can seep out from the base.
• Replace the wax ring: A damaged wax ring under the toilet can cause leaks at the base. Replacing it can solve this issue.
• Check and replace the flapper: Inspect the flapper for wear and tear. If it looks worn or damaged, replacing it can stop the leak.
• Adjust the fill valve: Ensure the fill valve is correctly adjusted and not letting water spill into the overflow tube.
