How to Fix a Hissing Toilet 

I have to say THANK YOU-#1 first for the fix it worked and #2 for not babbling on and on during your video. Straight to the point! Love it

Thanks...I like the FIXING instead of Replacing method. We are a throw away society of too much.....and simple repairs are not even contemplated. Thanks again!

My American Standard toilet started hissing and running about 2 months after it was installed. I had a Plummer come twice and they had no idea how to fix / nor did anyone have a clue at Home Depot. I just did this and it worked perfectly. Thank you, thank you, thank you!

This fix worked for me. Thanks for a clear, concise video!! Saved me from having to replace the whole unit.

Hi there! Appreciate your video very much. Ummm I’m not much of a handy man like my dad, but I just fixed the hissing toilet in our house without his help. Thanks for taking the time to make this video! Quick, simple, and straight to the point. ☺️

Thanks Dec! Saved me a trip to the hardware store! I popped the top off the valve, saturated a cotton pad with vinegar, let it sit on the valve seal a minute or two to dissolve the lime-crust, then used a Q-tip to gently loosen and clean off the crust. Easy fix!

Thanks for posting this helpful fixit video. It took about 2 minutes to rectify the problem with the help of your video.

Thank you for such a quick and simple video

Helped me a lot thanks it has a diagram same as irrigation valves cleared out the trash and it closed properly now

Thanks very much took me one minute. My wife was out shopping for a toilet yesterday.

Thank you Soo much!! That apparently was the problem, so helpful, again thanks!

Totally worked! Thank you!

Good video. Thanks

Fixed it. Thanks.

That shit worked. Good looking out!

Wooo! Thank you!!!

Thanks for the video. Unfortunately the hissing (which stops when I lift the arm) continues as does the slow to no fill toilet tank. The flow of water is powerful (I've tried flushing the Fluidmaster 2-3 times) and works for one flush but the hissing and weak to no fill picks right back up after the second flush.

My toilet makes a hissing flushing noise randomly.. I already flushed, cleaned, and replaced the rubber washer on the filled valve, also cleaned the red O ring of the flushed valve (it does not look worn out). I put some red food coloring in the water tank, it does not look its leaking 30 mins later into the toilet bowl. What else should I try?

What do you do if this doesn’t fix it?

What if the toilet hisses with the shutoff valve closed.

There’s still hissing but the water level is not rising.
