How to Replace a Flush Valve in a Toilet?

Here is how to repair the flush valve on a toilet

1. When you start repairing a flush valve, begin by turning off the water supply behind the toilet. This stops the tank from filling while you work. 

2. Next, flush the toilet to drain the water from the tank, and use a sponge to remove any leftover water so the inside stays dry. 

3. Now unhook the flapper chain from the handle and lift the flapper off the flush valve. Check the valve seat for cracks, wear, or mineral buildup. Clean it if needed. 

4. If the valve needs replacement, loosen the bolts underneath the tank and lift the tank off the bowl. 

5. Unscrew the large locknut holding the flush valve and remove the old valve from the tank.

6. Place the new flush valve into the opening and tighten the locknut firmly so it seals well. Make sure the rubber gasket sits flat against the tank. 

7. After that, position the tank back on the bowl and tighten the bolts evenly so the tank sits steady without wobbling. 

8. Reattach the flapper and connect the chain, leaving just a little slack so it moves freely. Turn the water supply back on and let the tank fill. 

9. Finally, give the toilet a flush to confirm everything works smoothly and the valve seals properly.

This is the right way to fix the flush valve on a toilet. Hope this helps you.

How do You Replace a Flush Valve in a Toilet?

Toilet flush valve replacement is tedious. You cannot do it yourself unless you are an expert. I had no idea on how to replace a flush valve in a toilet so I sat back and observed the entire work of NB’s plumber. Here is what needs to be done:

• Locate the shut-off valve near the base of the toilet and turn it clockwise to stop the water flow.

• Next, empty the tank by flushing and holding down the handle to remove most of the water.

• Then lift the lid and set it aside in a safe place.

• Unscrew the nut connecting the water supply line to the fill valve.

• Disconnect the flapper chain, unscrew the mounting nut, and lift out the old flush valve.

• Place the new flush valve into the tank and secure it with the mounting nut.

• Attach the flapper chain to the flush lever and screw the nut back onto the fill valve to reconnect the water supply.

• Open the shut-off valve to allow water to fill the tank.

• Make sure there are no leaks around the flush valve, adjust the components, and put the tank lid back in place.

• Flush the toilet to ensure the new flush valve is functioning properly.
