Repair a Toilet that continuously runs water (makes a "Hissing" sound)

This video will guide you through the process of repairing a new style toilet that makes a hissing sound, which is an indication that water is continuously running and you are wasting water.
The repair is quite simple and can be done by a single person without assistance.
You only need a brush (like a old toothbrush or other) to clean the underside of the flapper valve seal and the main water inlet valve seat.
Good Luck with your repair, and please feel free to leave any comments or questions and I will do my best to respond as best I can.

Thank you so much. The toilet was driving me insane. I didnt know you could twist that valve off. Fixed my issue.

[@Wire8T0]

I would have never gone inside that cap for a 30 second clean if it weren’t for this video. Fixed my problem. Thank you!!

[@audreyryan3719]

Thank you so very much! I followed your video, found a tiny bit of debris in the chamber, cleaned it out, reassembled and it worked!

[@brandenhart3768]

Been annoyed by hissing sound for days. This absolutely fixed it. Thanks for the video.

[@takefit4health239]

Thank you for your detailed instruction in this video. We just bought a new toilet and water was still running after tank was filled. Removed the debris in the fill valve and now it is quiet.

[@mikegecan192]

Tip on cleaning the intake valve seats worked great. Although I didn't actually see any contaminant on either surface (poor lighting and I didn't want to separate valve from the linkage unless I really had to) wiping both sides of the seal with a cloth then rinsing with clean water has cured the problem. Thanks again!

[@alexs5261]

Great video and explanation of all parts, totally fixed my hissing, little rock debris on fill valve seat, took apart, cleaned and snapped back together 👏 great

[@crodriguez320]

Just saved me a service call for something that was clearly explained and diagnosed. Excellent instructional video.

[@mball6433]

So I changed the flapper based on another video and still heard the water running. I tried turning the knob which adjusted the water level but didn’t stop the leaking. Just when I thought I’d have to replace the valve I watched this video and took the top of the valve off and cleaned the rubber and plastic (which I doubted would work). Working perfectly and stopped all running water. Thank you!

[@bonfeikao2457]

I just spent $500 to have the shut off valve replaced and new fill valve. Heard the ghost flush and hissing after the plumber left. I was very upset as the plumber told me if the water still runs then I need a new toilet. Googled this morning and found some debris in the chamber. No more hissing. Fingers crossed no more ghost flushing. Thank you!

Too bad you didn't find this video first. It would have been nice to know it could have saved you the $500 bill. Vito Casola - FIX IT Yourself!!

[@bonfeikao2457]

@@FIX-IT-Yourself I definitely still need to have the professional to fix the water shut off valve. That part was busted (20+ years of not turning the valve). It was like $200+ to fix the valve and another $200+ to replace the internal mechanism. I am just happy I didn't have to call them up again. I may have listened to them and replace the toilet. Yikes! Thanks for the video.

Thank you for saving me money!!! I totally did it on my own and it was a tiny little piece of debris that was the culprit. Thank you from Hawaii!

[@FIX-IT-Yourself]

Hi Melissa, Glad you found my video and it was helpful for you. Mine had the same problem, tiny piece of debris. You're so lucky you live in paradise. How is it there now with the pandemic. Last time we visited Hawaii was back in 1999 for our 3 week honeymoon (4 days in Oahu, 8 days in Maui, and a 9 days in Kauai). Still hoping we will be able to visit the islands again some day. Keep it beautiful for us until we come back. Vito Casola - FIX IT Yourself.!!

@@FIX-IT-Yourself please come back one day! The lockdowns were a but surreal, I hadn't seen Oahu this quiet since the 80s. But the tourism and busyness is slowly returning. You might find it more crowded but the beauty hasn't changed. Thank you again for posting this video, stuff like this gives me confidence to do more DIY fixes. 🤙🏼

[@FIX-IT-Yourself]

@@mahnli Thanks Melissa, That's been the plan for sure, to definitely make it back to Hawaii one day this time check out the Big Island and I'd sure love to Kauai again and if time permitted Maui and Oahu. You're most welcome. The reason I started making these videos was to help people realize most things can be fixed by the homeowner if they just get a little guidance, enough to encourage them to at least try, so I'm glad to hear that in your case it did exactly that. Take care and keep the islands beautiful, it truly is a Paradise on Earth. Vito

[@mossmiller]

After just 3 weeks my new Kohler toilet with the yellow-cap Fluid Master started running on as described here. Followed this video and it is fixed. Did not see any debris on the black washer, but did the flush under the cup as described. Thanks for making this video!

[@FIX-IT-Yourself]

Hi Moss, Thank you for your comments, it's really appreciated. I'm glad the video helped you fix your issue. I know it's not the toilet but just the smallest piece of debris that may get stuck inside the valve assembly under the washer and sometimes it will pass through and other times it will get stuck and cause the continuous running of very small amounts of water and you hear the hissing sound. I too was baffled when I first noticed hearing the sound. It was late at night when everything was quite and the furnace wasn't running and when I had to put my head close to the toilet I noticed the hissing and that's when I started exploring where it could be coming from. Anyway I'm glad my experience is helping others. Vito Casola - FIX IT Yourself.!!

[@rebeccawinchester7538]

Thanks. None of the other videos addressed this problem! That yellow cap didn't want to come off, but when it did, the toothbrush and the cup over the water test proved great!

Thank you so much for this video!!! I watched several on how to stop the toilet running but none of them offered the solution. You suggested cleaning the valve and showed how to take it apart. My toilet is American Standard, so it has a similar assembly. Lo and behold, cleaning the grit out did the trick. My daughter and I worked as a team (she's a nurse) and with tweezers and a dental floss gadget, we got 3 wee stones out of there. It felt like a medical procedure. :).

[@MarkEichin]

Thanks for stepping through all of the detail - I've done easy fixes on old-style toilets, but finding all of this plastic in a new one I was afraid I was going to break something just trying to make adjustments. (Same "hissing", the fill valve was refusing to close all the way even if I pulled the float up hard; sure enough, taking the top flap apart and brushing everything off was all it took.) Also thanks for the "just turn the water back on only a little at first" - seems obvious but it hadn't occurred to me and is a really good idea.

[@jldossey45]

I have to thank you for your video. You were the only ne I found exlaining the FILL VALVE, BUT...... when I was taking everything apart, I discovered something I had only seen one time. I had a "BUBBLE" in the yellow seal. I used a NEEDLE to puncture it and get the WATER out of the bubble which had been holding my seal apart from sealing. Of all thee videos about how to change the round valve in the bottom of the tank, NO ONE had indicated that the valve could be defective and allow a little bubble full of water to cause the tank to slowly leak. Thank you for taking the time to make your video. You did an excellent job.

Thanks for the great video. Was able to fix my hissing leak just as you demonstrated. Before I viewed the video I was trying to see how the valve worked but couldn't get past taking the yellow cap off: didn't know how much force where to get it off without breaking something. Likewise the '1/4 turn to the left on the valve' to take it off. Better than trying to pry it out with a screwdriver :)

Thank you for this detailed video! You saved me from calling a plumber. Much appreciated 😊

[@RubenRyb66]

Nice. I've replaced the generic fluidmaster kind twice. What I Noticed about those is the entire assembly comes out with the top cap. So it would be easy to just flush and brush it out under some hot faucet water lol. Good thing they are relatively inexpensive so I didn't lose out to much by just replacing them. Still good to know you usually don't need to replace the entire regulator. Another common mistake that causes toilets to run is shoving the rubber tube into the overflow drain instead of using some kind of clip that holds it above it. If you shove it into the overflow it ends up syphoning the tank water.

[@summertime1438]

[@richiepawlowski6848]

When I take the cap off it's spraying lightly underneath out of the top. Is that due to a bad gasket or is the entire assembly broken? It's night so I don't want to mess with it right now in case of emergency the stores are closed. I did remove the washer gave it a good cleaning and flushed water through the valve by turning the water back on and it still hisses and sprays. Thoughts? Can just the valve fill assembly upper portion of this part be replaced?

Hello, I hope you will help me. My KOHLER Highline Classic White WaterSense Toilet keeps running water. Could you advise me on what I might need to do to solve the issue?

I am overwhelmed...

[@FIX-IT-Yourself]

Good Morning Donna, I'm sorry to hear about your husband. Regarding your toilet is it the toilet bowl itself that is filling up too much or the tank which holds the water until you flush? If it's the tank then you should be able to adjust the water level height. If you remove the lid on the tank take a photo of the inside of the tank and email it to me at [e-mail] and I will see what type of mechanisms you have inside. Then I might be better able to assist you. Vito Casola - FIX IT Yourself.!!

I replaced the fill valve washer, its still making the hissing noise intermittenly, no leaking from the fill cap area.. maybe its the flush value O Ring causing the hissing? I will try also flushing the fill valve first.

[@FIX-IT-Yourself]

Hi Wendy, Thank you for your comment. I guess it could be but I would double check the fill valve area first and make sure to flush out any debris that may have gotten lodged into the rubber seal. Be sure to rub your finger all around the fill valve seal and flush the entire area, as I showed in the video, by putting a small empty margarine or yogurt container upside down and turning on the water to allow a good flush. Then reassembly everything and see if that cures it. If not and you did already replace the inlet valve seal then, yes maybe time to check the flush valve seal by lift it and rubbing your finger around the bottom of the seal and seat to ensure no debris is sitting between them. Good Luck. Vito Casola - FIX IT Yourself.!!

So in my case the water comes through the grey top under the yellow cap and causes the hissing sound. It continues to come through even if I turn off the water. I guess I have to replace the whole thing but at least I’m not really wasting water in the meantime (Water goes back into the tank)?

Hi T, That sounds really strange. If you turn off the water at the source it still makes a hissing sound? You sure you shut off the main water line feeding the toilet. Sometimes the little black round rubber seal gets old and doesn't seal good anymore. In that case you need to replace only the rubber seal. This happened to a friend of mine and we tried putting the seal in a pot with boiling water to see if we could get it to soften up a bit but it didn't work. In the end she went to home depot and purchased a replaced rubber seal for like $5, put in back in the toilet and it worked like a charm. Vito Casola - FIX IT Yourself!!

What if I cleaned it, I replaced the yellow gasket and it’s still hissing? What would be another solution?

[@CS-ns4ge]

I cleaned the part but after I did a test flush, the water came up to where it should, the hissing continued. There is water leaking from the fill cap area. What do I do?

[@FIX-IT-Yourself]

Hi C S, Cleaning that area where the gasket will sometimes cure the problem but if the hissing continues it means water is still leaking and you will have to replace that rubber seal. As the rubber gets old it also gets harder and less pliable so it doesn't seat perfectly and create the seal. I actually had this happen to a friend of mine and she watched me try to repair by just cleaning and it didn't work. We tried putting the old rubber seal in boiling water for about 10 minutes to see if that would help make the rubber softer but that too didn't work. In the end I told her to just go and buy a new seal. She went to Home Depot and bought a new one for less than 5 buck. After watching me try to clean the old seal several time she was able to installing the new rubber seal herself and then it worked perfect. Good Luck. Vito Casola - FIX IT Yourself!!
