How to Stop a Leaking Toilet: A Step-by-Step Guide

Written by LJ’s Handyman Service Inc.

A leaking toilet is not only an inconvenience but can also increase your water bills and lead to potential water damage if left unchecked. At LJ’s Handyman Service Inc., we understand the importance of promptly addressing such issues. Here's a straightforward guide to help you tackle that troublesome leak:

1. Identify the Source:

- Tank Leaks: Add a few drops of food coloring into the tank. Wait about 10 minutes. If the color seeps into the bowl, you have a flapper leak.

- Base Leaks: Check the base of the toilet. If it's wet, the wax ring seal might be compromised.

2. Turn Off the Water Supply:

- Before you start any repairs, turn off the water supply valve located typically behind the toilet, then flush the toilet to drain the tank.

3. Fixing a Flapper Leak:

- Open the tank lid.

- Examine the flapper. It should be free of debris and create a snug seal.

- If the flapper looks worn or warped, replace it. Most home improvement stores carry universal flappers.

- If the flapper is clean and intact, adjust the chain connected to the flush handle. It should have a slight slack, not too tight or too loose.

4. Addressing Base Leaks:

- If the leak is at the base, the wax ring might need replacement.

- This involves unbolting and lifting the toilet, a task that might require two people.

- Once the toilet is removed, the old wax ring can be scraped off, and a new one can be put in place before reinstalling the toilet.

5. Check the Fill Valve:

- Sometimes, the leak may be due to a malfunctioning fill valve.

- Ensure it's correctly adjusted, and the float isn't set too high, causing water to spill into the overflow tube. If the fill valve seems faulty, consider replacing it.

6. Turn On the Water Supply:

- Once you've made the necessary repairs, turn the water supply back on and monitor the toilet for any further leaks.

7. Seek Professional Help:

- If you've tried the above steps and the leak persists, it might be time to call in the experts. At LJ’s Handyman Service Inc., we're equipped to handle all your plumbing needs, ensuring your toilet functions seamlessly.

A leaking toilet can be a simple fix, but sometimes it's indicative of a more significant issue. Regular checks and prompt attention to anomalies can save homeowners both money and stress. And remember, when DIY solutions don't seal the deal, LJ’s Handyman Service Inc. is just a call away.
