How to Fix Niagara Stealth Toilet for under $2.00 - Hissing Noise & slow water fill with weak flush
Тәжірибелік нұсқаулар және стиль
My Niagara Stealth toilet (model N7714) had a hissing noise, and I discovered it was due to the fill valve filling the tank with water very slowly. This also produced a weak flush when the water had not yet completely filled. I searched online for answers, but the company has only one troubleshooting video that did not help. I then called the Niagara customer support line, only to be left on hold for over 90 minutes and never get through to a representative.
Since I have 2 of these toilets in my house, by trial and error I found the culprit was a Fill Valve Seal. I bought this item on Amazon at the following link for $1.68 - www.amazon.com/Fluidmaster-242-Toilet-Valve-Replacement/dp/B00002N6MK. I will not make any money if you click the link, it is just there for your reference.
In this video, I show the original problem, how I replaced the valve seal, and how the toilet was fixed after a quick 5 minute repair. I bet a lot of folks change out the whole entire fill valve assembly, which costs more money, takes longer, is messier, and adds unnecessary plastic waste to our landfills.
I hope this video will help a lot of folks avoid the hours spent on troubleshooting that I did, and fix your toilets quickly and easily. I cannot guarantee that this valve will fix whatever problem you are having, but if you hear the same hissing as in this video, and if it takes a long time for your tank to fill like mine did, then this should do the trick.
If you have a Niagara toilet, you can find your model number by lifting off the tank cover, and looking at the back wall inside the tank where the model number should be printed. My research showed that this Fluidmaster Fill Valve Seal will fit the following Niagara toilet models:
NANO Dual Flush Compact Elongated 12” model # N7747T-DF
PHANTOM Single Flush Elongated 12” model # N7747T
ONE PIECE Single Flush Elongated 12” model # N7711
THE ORIGINAL Single Flush Elongated 12” model # N7714
THE ORIGINAL Single Flush Round 12” model # N7714
THE ORIGINAL Single Flush Round 10” model # N7714
THE ORIGINAL Single Flush Elongated 12” model # 77000WHAI1
THE ORIGINAL Single Flush Round 12” model # 77001RWHAI1
THE ORIGINAL Side Handle Single Flush Elongated 12” model # N7714TFH
THE ORIGINAL Side Handle Single Flush Round 12” model # N7714TFH
THE ORIGINAL Side Handle Single Flush Round 10” model # N7714TFH
THE ORIGINAL Dual Flush Elongated 12” model # N7714T-DF
THE ORIGINAL Rear Outlet Single Flush Elongated 4” model # N7799T
However, it will NOT work in the Niagara SENTINEL model # N2235T.
Please keep in mind that the particular Fill Valve Seal used in this video works in any toilet using the FluidMaster 200, 400 and 747 models - not just Niagara toilets.

You saved me so much time and energy in diagnosing the problem, I was about to replace the toilet bowl. Every time I flushed the toilet, I would be so upset, watching the water running for several minutes. What an unnecessary waste of water. I tried several times to diagnose the problem but wasn't able to. I can't thank you enough!
This man is a legend. My toilet would flush once, then not fill back up, then the next flush was weak. This fixed it. Now it flushes and fills back up...like a toilet should!
Dude! You have no idea! Literally the only person on KZread that’s suggesting this idea! My toilet wouldn’t stop filling and that rubber fill valve seal replacement fixed the issue! (PS Niagara website has replacement parts form for free incase y’all need other replacement parts ) ‼️I think you need to repost this video again , with a more general title “leaking toilet fill valve” so more people can find YOU!!!! I only found you because I was googling for “Niagara toilets” in specific, I wouldn’t have found you otherwise! (The first time I had this issue I ended up replacing the whole fill valve because what’s what all the videos were doing NO ONE mentioned that rubber seal) Thank you a million! Learnt a lot today!
Thank you so much for posting this! This fixed my running toilet that I've been suffering with for months because I didn't want to have to pay for a plumber.
This works for the N2450T as well! Tiny grains of sand were below the seal. After cleaning the toilet worked perfectly, good flush and quiet refill. THANK YOU SO MUCH!
I installed three of these systems on the same day at my house. They all began to fail around the same time, and my inner conspiracy theorist swore that I was a victim of planned obsolescence. Maybe I am, but this TOTALLY helped all three toilets! Thanks a million!

I have 2 that are about 3 years old and both started this on the same day. I found little pieces of sand in both that were causing the problem. Think something just gets in the lines and goes to all the toilets. Happened a again few months later. Found another small grain of sand. Was the issue for me.

Thank you!!!! We bought this toilet, 1 week later it would keep running. After following your steps it works normal again!!!!
one thing u might add in your next video.... a general knowledge of how that flush valve works with suction etc... for the Niagara. Thanks for your knowledge!!! p.s. Had my Niagra about 20 years now... & this is the first time I had to troubleshoot it.
Dude, thank you so much! I recently moved into a new place and the toilet took forever to fill up it was driving me nuts! This was the exact fix I needed, thanks for your information and great video. Cheers!
You're the Mannnnn!!! I'm a 66 year old Female I fixed the toilet hissing by myself, with your video. I couldn't remove the screw adjuster thing once I dislodged the part under the cap. Too scared I was going to break it. So once I dislodged the piece counter-clockwise, I turned the part so that I could remove the seal. And then popped in the new seal and put the part back on turning clockwise to set it, I put the cap back on. Turn the water on. I flushed twice, and waited. Then my husband peeps his head in the door and says,how you comin' Baby. I said I think I fixed it. I don't hear no noise 😡 I guess I have to call and cancel the plummer.

Thank you so much! I am a novice at fixing things around the house. You saved me some $$$.
Thank you so very much for making such a simple yet greatly detailed video. I’ve been dealing with this issue for months and was kinda trying to ignore it. I am not as handy as some but after watching this video a few times I felt confident. I quick trip to Home Depot, they had the new Fill Valve Seal and the problem was solved within a few minutes after getting home. Really, this should be the template for “How-To or DIY” video on KZread. Simple and to the point. Thank again, best wishes and positive vibes sent your way.

Hey, thanks for posting this video. Was able to fix my toilet with the help of your video!
Thanks for the video. It helped a lot!!!
The video showed the symptom I was encountering and the solution that brought the Niagara Stealth back to the condition it was in when I installed it two years earlier.
Thank you soooo much. I wish I could like this video 100 more times.
Was just about to buy the whole valve assembly. Save me some time and money. Thanks
I should just keep this part on hand. Feels like I always have to replace it. lol thanks for your help!
Thanks for this. We have a few toilets with a similar Niagra model. This seal worked on the first flush.
Thanks for posting. This video solved my problem! Perfect.
Thank you so much, I have the exact same toilet you're working on and I had to pop it open for the second time because I kept hearing it hiss off and on, well thanks to you sir I know now don't I LoL. Great informative video. Gracias Señor.

What is the name of that black part in the middle of the white circle?
Thank you! I fixed it without a plumber.
Was wondering if anyone knows how to take the water saver part out?
Thank you for the video
Thank you kindly Sir.
I am going through some trial and error and I have a glacier bay model that has the niagra stealth setup that advertises it is capable of flushing 12 billiard balls and believe me it will, but yesterday it suddenly lost flushing power completely and I know that it isn’t clogged at all because I have dumped a 5 gallon bucket of water in the bowl and it drained immediately and when it happened I instantly noticed that the jet power that is usually present when flushed wasn’t there at all and water was slowly draining out but no typical flushing spiral 🌀 like you would normally get. So I’m just wondering what is causing this to happen
Thank you so much I was wondering what I had to do with my tank.
Awesome video. How about if the seal valve is good changed. And it still talking up to 3 minutes to fill the tank back up. What can be done?? Thank you brotha!
Thank you
My case was not working with just changing the leaky seal. I had to replace the whole fill valve unit.
Hi how much water it used?
I think i need for my toilet from over flowing.. it's not an hissing noise, it just continues to fill pass the damn margin...i tried turning that screw that right from the same thing you reassembled...
Will this solve ghost flushing??
Thanks - this looks useful. My Niagara toilet makes the noise when the fill is complete. Can you say if replacing this valve will help that?

Yes, it should. Or just the seal should do the trick.
I have the Stealth Toilet N7714 in my home. My toilet cannot automatically fill with water. I need to push or move a little bit on the black arm of the float to allow water to come into the toilet. Could you please provide me with some suggestions on how to fix it? Thank you so much

Thank you very much. My unit is less than a year old and all of a sudden the hissing started. With your help to get inside and get the gasket. It looked okay so I just cleaned it with a cloth only and wiped the inside down, reassembled and problem was solved. We are noted for hard water I live and I think the build up was the issue. seriously great video though....It helped me for sure.
Hi #AxMan .. I did this suggested repair and changed the little black valve. The hissing/sqealing sound has stopped, BUT.. now the water won't stop running! I tried adjusting flush button and valve arm to no avail. Please help! This toilet is less than 3 years old! (N7714)

Sounds like the adjustment screw for the valve water level in the bowl could be the problem. Or maybe there is a leak on the seal on the bottom of the tank. Sorry for the late reply, I don't come on here a lot.

I have the same dagum Problem on N7714 toilet fill valve gasket replaced and hissing noise stopped. However the gasket seems too small as now it just keeps over filling tank. Even after I left of the arm on the fill valve water keeps flowing! Only the old gasket that makes a hissing noise will stop the fill valve! 💀🙏🏼

I came to your channel because our toilet is hissing. I noticed that you just tapped the button and it flushed all the way. We have to hold our button down even with the lid off to flush completely .

@smarzig Yep, that could be a problem. I played the video back a couple of times to make sure I put the seal in correctly.
Would replacing the fill valve seal fix my problem? Toliet flushes normally, then water level falls after the bowl fills up. Thank you.

No, you probably need a new seal on the flush valve (not the fill valve), or you might have a slow leak. It's a very common problem on the Stealth toilets. Watch the KZread Stealth video called "Stealth Toilet - Troubleshooting" and watch the part about checking the flush valve, then check the white seal on the bottom of it, try hand cleaning it, and/or replace if necessary. Good luck.
How high can the water level be increased with that stealth mechanism in there? Looks like there's a bit more room to available?
