How to Replace a Toilet Flush Valve

Replacing a toilet flush valve is an essential skill that can save you time and money. While you can always hire a professional like VK Gas Plumbing for guaranteed workmanship, it’s possible to tackle this task yourself if you’re comfortable with basic plumbing jobs. Here’s a step-by-step guide:

Gather Tools and Materials

Before you start, you’ll need:
A new toilet flush valve, Adjustable wrench, Sponge and bucket, Towels or rags, Rubber gloves.

Turn Off the Water Supply

Locate the water supply valve behind the toilet and turn it off by turning it clockwise. Then, flush the toilet to drain the water from the tank. Use a sponge to soak up any remaining water.

Remove the Tank

Disconnect the water supply line from the tank. Next, remove the tank bolts using an adjustable wrench. Carefully lift the tank from the bowl and place it on a towel or rag.

Remove the Old Flush Valve

Inside the tank, you’ll see the flush valve, typically located in the center. It’s usually held in place by a large nut underneath the tank. Remove this nut, and you should be able to lift the old flush valve out of the tank.

Install the New Flush Valve

Place the new flush valve into the same position as the old one. From underneath the tank, screw on the provided nut to secure the valve in place. Don’t over-tighten, as this could crack the tank.

Reconnect the Flapper Chain

Attach the flapper chain to the flush lever, ensuring there’s a slight amount of slack in the chain. Too tight, and the flapper won’t seal properly, causing the toilet to run.

Reinstall the Tank

Carefully position the tank back on the bowl, aligning the mounting holes. Insert the bolts and tighten them gently—again, don’t over-tighten. Reconnect the water supply line.

Turn On the Water and Test

Turn the water supply valve counterclockwise to turn it back on. Let the tank fill, then flush the toilet a few times. Check for leaks and proper flushing action. Adjust the flapper chain length if necessary.

Final Checks

Make sure there are no leaks around the base of the tank where it meets the toilet bowl, and the flush operates smoothly. If you notice any issues, you may need to adjust the flush valve or the flapper.

Why Does My Toilet Keep Running After Flushing?

A toilet that continues to run after flushing can be an annoyance, not to mention a waste of water. While the constant sound of water can cause concern, the silver lining is that the fix is usually simple. Understanding the common causes can turn a seemingly complicated issue into a manageable DIY task.

Common Causes and Fixes for a Running Toilet:

Faulty or Dirty Flapper:

The flapper is a rubber valve that stops water from flowing from the tank to the bowl. Over time, it can become dirty or wear out, preventing a tight seal. Cleaning or replacing the flapper usually resolves this issue.

Improper Chain Length:

The chain connects the flush lever to the flapper. If it's too long or too short, it can prevent the flapper from sealing properly. Adjusting the chain length can often solve this problem.

Misaligned Float:

The float controls the water level in the tank. If it's set too high or becomes stuck, water will continue to flow into the tank and down into the overflow tube. Realigning or replacing the float might be necessary.
