In this video
Slowly turn the water supply valve back on. As the tank fills, check for any leaks at the base of the toilet where you made the connections. Let the tank fill completely. Flush the toilet several times to ensure it flushes correctly and the fill valve operates properly, refilling the tank without sticking. The new valve should work smoothly with each flush.
Goal: Verify the repair and check for leaks
- Turn the water on slowly at first to check for major leaks before fully opening the valve.

FAQs
Is replacing a toilet fill valve truly a beginner-level DIY project, and what's the realistic time commitment?
Yes, it's considered a beginner-friendly project as it primarily involves basic disconnections and re-connections. While the estimated time is 2 hours, many experienced DIYers can complete it in 30-60 minutes. For beginners, the 2-hour estimate allows ample time to understand each step and troubleshoot any unexpected issues.
What are the essential tools I absolutely need for this project, and are there any acceptable alternatives for the specific wrenches listed?
You'll primarily need pliers and an adjustable wrench, such as the Husky 12 in. Adjustable Wrench mentioned. While a specific basin wrench can be helpful for tight spaces, a standard adjustable wrench or channel lock pliers usually suffice for the large fill valve nut. Ensure your chosen wrench can open wide enough to grip the nut securely.
What's the most critical safety or preparatory step to ensure I don't cause a flood or bigger mess?
The most crucial step is to completely shut off the water supply to the toilet before beginning any work. After turning off the valve, flush the toilet several times to empty the tank as much as possible. It's also wise to have a bucket and old towels, like the FRESHFOLDS set, nearby for any residual water or small drips.
After installing the new fill valve, the toilet constantly runs or refills too frequently. What should I check?
First, verify that the fill valve's float cup or mechanism isn't obstructed and can move freely up and down. Then, adjust the fill valve's height and water level screw to ensure the water stops filling about 1/2 to 1 inch below the top of the overflow tube. Also, inspect your toilet flapper for a proper seal, as a worn flapper can often be mistaken for a fill valve problem.
