How to Repair a Running Toilet

A running toilet: one of the most common (and annoying) household issues. We’ve all been there—late at night, trying to fall asleep, and all you can hear is that constant trickle. Don’t worry; Vaquero Plumbing has got your back. Let’s handle this toilet repair together!

How to Fix a Running Toilet

Tools and Materials Needed

Before we get started, let’s make sure we have everything we need. Here’s a quick list:

• Adjustable wrench
• Screwdriver
• Replacement parts (flapper, fill valve, flush valve, as needed)
• Towel or sponge (for any water cleanup)

Now, let’s get to it!

Step 1: Turn Off the Water Supply

First, we need to stop the water flow to the toilet. Find the shutoff valve behind your toilet and turn it clockwise. Trust me, nothing’s worse than getting soaked because you forgot this step. Learned that one the hard way!

Step 2: Remove the Toilet Tank Lid

Carefully take off the lid of your toilet tank and set it aside. These lids are fragile, so be gentle. I once broke one and spent the next hour cleaning up and feeling pretty silly.

Step 3: Inspect the Flapper

What’s a Flapper?

The flapper is that rubber piece at the bottom of the tank. When you flush, it lifts up and lets water flow into the bowl. If it’s not sealing right, water keeps flowing.

Checking the Flapper

• Take a good look at the flapper. Is it warped, torn, or just looking old?
• If it’s not sealing properly, you’ll need to replace it. Turn off the water supply, flush the toilet to drain the tank, and unhook the old flapper.

Replacing the Flapper

Head to your local hardware store and grab a new flapper. Make sure it matches your toilet model. Install it by hooking it onto the flush handle and ensuring it sits properly over the valve seat. Turn the water back on and give it a test flush. If the running stops, you’re golden!

Step 4: Check the Fill Valve

What’s a Fill Valve?

The fill valve controls the water level in your tank. If the flapper wasn’t the issue, this is your next suspect.

Inspecting the Fill Valve

• Flush the toilet and watch how the fill valve operates.
• If it doesn’t shut off, it might be stuck or damaged.
• Adjust the float arm to make sure the fill valve shuts off at the correct water level.

Step 5: Replace the Fill Valve (if necessary)

When to Replace the Fill Valve

If adjusting the float arm doesn’t do the trick, it’s time for a new fill valve.

How to Replace the Fill Valve

Turn off the water supply, flush the toilet to empty the tank, and follow the instructions on your new fill valve for installation. It’s easier than it sounds, promise!

Step 6: Test the Toilet

Turn the water supply back on and let the tank fill up. Flush a few times to make sure everything’s working properly. No more running? Success!
