Thank you so much! I’m a 73 year old widow who is too thrifty to pay a plumber to do a simple repair of my “singing” toilet. I had the part and then discovered that Toto hides the water line and fill valve connection. I appreciate you providing the answer. Repair is complete and it is successful!
Thank you! I knew I had to replace a fill valve but once I tried accessing it I found out how "lovely" it is to work on this toilette. Thank you kindly for the step-by-step guide!
Fantastic video! I didn't realize I needed to take the tank off but your video explained why and showed how easy that was. Original fill valve lasted 14 years, hope this Toto made in USA replacement lasts another 14 years. Thanks for posting this!
Just rewatched this as the other toilet fill valve just went out today as well. Almost like clockwork, these things can last 14-15 years, amazing. Made in USA!
Don't panic! Taking the tank off is trivial. Wedging your body between the toilet and the wall in futile efforts to loosen the fill valve externally (which is trivial on most other toilets) is impossible. I tried. After several tries with replacing the filler cap and basically cannibalizing a fill valve to replace every component I could without removing the tank - I gave up and removed the tank. I thought it would be a messy chore. It was easy peasy. Once you decide you need to repace the entire fill valve - don't waste time. Go straight to tank removal. Thank you for this video which gave me the kick in the pants I needed. My only complaint is that you skip the whole tank removal process at 5:40 - which kind of scared me a little...why didn.t you show what I thought (to me) the most difficult part of this process? Do not fear- take the tank off!
Thanks for the video. I used it yesterday to replace my fill valve on an ST413 Aquia. I found that I could completely close the little black adjusting valve that adds water to the bowl because the Aquia water spot (I belive that is the term for the surface of the water in the bowl) is self regulating. Running water through the little hose as is done in other bowls does not seem to be necessary, just wastes a little bit of water with each fill. As for comments about Toto quality, this was the first repair the toilet has needed in almost twenty years of constant use.
Thanks so much for this video. I have the exact same toilet. I've replaced the fill valve on other toilets with no issue. Come to to toilet...yikes. I couldn't get to removing the water hose. I didn't realize you need to remove the entire tank! I'll do it tomorrow with a new disc on hand. Very informative video, you saved me :)
Thanks so much for making this video. I have a two piece ST413 that is impossible to change the fill valve without removing the tank. I was concerned that removing the tank bolts would be a difficult procedure, but how you explained they are actually studs from the bottom going into the bowl to be tightened by the bolts from the top now makes it clear it's not that difficult. I wish Toto didn't make their ST413 toilets so difficult to access from below to make changing the fill valve into an hours long process.
Thank you! Your video was so helpful! I procrastinated doing this job for months because I didn't know how to deal with the closed design. Got it done and so far, so good.
This is a sick video! I just got called from my customer at 10pm and when I saw the toilet I wasn't sure what to do until My thought were agreed with the same idea in the video to take the tank off and replace the valve. Done in 20 mins. Many thanks!
Great video! - just replaced the valve. The hardest part was replacing the damn nuts! Eventually taped the nut to the screwdriver, and then could accurately place it before screwing it in.
Worst design ever that gives no access underneath. I had to use duct tape on a skrewdriver too.
The house I moved into had this toilet. I’m somewhat handy and had no idea how to change this valve. Watched this video and had it disassembled and put together in 26 minutes and that included trips to the basement for tools. Didn’t even have time for a second beer 😂.
So well explained! The video emphasizes steps to take in order to remove the valve. I was so upset and scared when one day stepped onto flooded floor and had no idea what caused the leak. In my case a plumber, who replaced galvanized pipes with new plastic pipes a year ago, did not bother to screw in one of the screws in the tank. It just fell out when I touched it. No idea how all these months it held the water. So thanks so much for this lesson!
Great video. Got the confidence and end up fixing my toilet very comfortably. The hissing sound means to change the water shut off valve. The earliest the better.
Thanks a lot for reminding me the flat screw driver bolts for removing tank. I did it before but forgot how and my bad eyesight couldn't see the screw thread... You saved my day!! This toilet was a nightmare to install that required drilling holes on my hard porcelain tiles, maintenance is even worse with no access from below at all! Value needs to be changed every so often with tank removal. The new Aquia Vi has greatly improvement on the rear access but we need to live with this bad old design for a while..
Truly appreciate you taking the time to make this video! Helped me tremendously
Good video! I was afraid I would have to remove the entire toilet to replace the fill valve, I'm grateful to you for showing me that I can remove the tank, fairly easily it seems. Also, I now can see it makes sense to have all new gaskets on hand before starting the project - may as well do those at the same time!
Great Helpful video! As noted by Mister Brown below Toto instructions say not to use in tank tablets due to the chemicals affecting the workings of both fill and flush valves. Since you stated your toilet was only a couple years old using the in tank chemicals may have been the reason you had to replace the fill valve so soon.
Just food for thought but again thanks for the very informative video
Thanks for the video. I am a plumber and can tell you that watching helped me prep for installing 4 fill valves for a customer. Helpful.
Great video, thanks!
Following up on this. Turns out it was only my Fill Valve Gasket Cap Seal that was worn out. You can buy the whole Cap for about $6 on Amazon.
You can access the Cap by pulling out the Fill Valve Cover. There are other videos you can search explaining how to replace the Cap. (Maybe you should do one of your own to complete the series?)
If you're having issues with your Fill Valve, I'd recommend checking this out first because there's not much else that can go wrong w/the Fill Valve.
Thanks a lot for the video as it led me to the solution of only replacing the Fill Valve Gasket Cap Seal.
Awesome video! Thanks! Helped me to fix this monster..
Thank you so much. Yes, this toilet design is ridiculous!
Just found this out when I changed the valve, have to take the whole tank off!!! Easy way is to just replace the seal cartridge inside the fill valve
that is true most of the time. I have already replaced the filler cap a few times. This last time - I need to replace the entire valve. It is still a mystery to me why these are so finicky.
That’s what I did too. Have replaced it several times. It’s a 5-minute and $5 fix. But after 14 years, that no longer works, and I have to replace the whole pump.
is the blue button for the small flush or the big flush?
i noticed when pressing the blue button, most of the body lifts up but pressing the white button, only the bottom lifts up so shouldnt the blue button be the bigger flush? im not sure why the buttons are placed the way it is..
Thanks for the video, just replaced mine, after first trying to replace the valve cap on top and cartridge gasket on the bottom.. which didn't fix the hissing......
You're bang on. Possibly the dumbest design ever. I've had to do this twice now. Had one tank crack about 2 weeks after changing the valve.
I have to change the flush valve and was confused how it comes off… so just disconnect the water line and unscrew the screws? No need for bolts under the screws below the tanks? That’s what I was worried about because it was hard to reach…thanks
Thanks for this great video! How did you get the tank detached? Which tools did you use?
Thank you for sharing.
Thank you. Have the same model and could not figure it out. Appreciate that you explained how to remove tank! Please do one to show how to remove the flapper.
Is there any reason that a little water would still be trickling into the toilet bowl after installation? Maybe that black ring/seal is off center or needs to be replaced?
@mechtrician1 Great video. Do you have a link to buy that exact entire flush valve tower set? I can't seem to find it on the Toto website
Thank you so much - this saved me!
Cleaning agents in the tank will ruin all seals. Voids manufacture warranty as well.
Not sure how that would kill the fill valve though, but duly noted. I can see that killing the flush valve. I stopped using the tablets anyway, they don't really do anything.
Hello. Can you show us how to change the FLUSH VALVE and TOILET SEAT.
Being that the fill valve was such a bad design to change, I bet that the
FLUSH VALVE and TOILET SEAT
has the same Silly design.
It would be much appreciated.
ST416M. All the best, Mike i.
Thanks for the video Sir.
I have not needed to change the flush valve yet, but I believe it is changed in the same way where you have to take the tank off and remove the big nut from the bottom of the flush valve. I have taken the seat off before and it sucks. You have to remove the toilet from the floor if I remember correctly. That's the only way to access it from the rear to hold the nuts for the seat bolts. Luckily, the base seal is reusable and doesn't need to be replaced like a wax one.
I had to replace the flush valve recently and you will need a new Toto part number as the version that is shown in this video is EOSL. Highly recommend replacing all washers and gaskets as this design requires major toilet surgery. Same process - no easy way out. The good news is mine lasted well over 10 years.
You’re brutal with the commentary
It’s my style. There’s a lot of other CZcams channels out there.
@mechtrician1 The mounting hardware bolts and screws seems a very pricy amount-$90+CAD. I just need the washer as it is disintegrating. Can I buy any regular washer or does it have to be specific? It seems Toto parts are all special 😮
Thanks for the video!!! How do you think I could get new rubber washers (tank to bowl) without having to buy the whole set of bolts? For the set they charge $45!!!
Thanks
Hi there, thanks for the video. We have the exact same toilet, and have had it since we moved into our house. The water level in the BOWL is always very low. And I don't seem to see how we could adjust that on this particular toilet.
Is this model just known to have a very low water level in the bowl or am I missing something?
As a bonus, the bowl seems to fill up the same amount regardless of whether or not the tube is connected to the bowl refill on the flush valve??? However, I can easily confirm there is water running through the line when it is disconnected.
Any help or information would be appreciated.
The water level is designed to be very low. My plumbing supplier here warned me when I bough the toilet that some people don't like the small size.
I’m about to do a one piece one, betting I’m gonna have to pull and reset it to get to the flush valve nut.
I have this. The toilet is stylish but ergonomically terrible for DIY repairs. You have to take the bowl off to remove the valve.
All you had to do was: replace the fill valve seal on top of the assembly - not the whole assembly
Yeah, I believe I mentioned that at some point in the video when I noticed it came apart.
I have this model and it's newly installed in my new apartment. For some reason the water won't refill though despite being new and will only refill if I push on the green part and lean it in a certain direction. Any suggestions for this seemingly simple problem? Thanks
I have the same problem. I have to tap the green cap to trigger the refill right away. Otherwise it would refill after a few minutes (unpredictable). Please keep me posted if you find a fix. Thanks!
@@superdanchan I’m gonna ask my plumber. Will let you know
Hi! Thanks for this video - I was wondering how to replace the fill valve with that skirt around the toilet - I think I will first try the seal cartridge and then maybe the upper half of the fill valve - but being in Canada, I am not sure about these replacement part numbers... do you know the numbers of these items? Worst case scenario, I will order from the US (luckily we have more than one toilet!).
I think I listed the link in the description for the whole full valve. Not sure about any other part numbers without some research though.
@@mechtrician1 Thanks again, ordered from Amazon!
How you remote the two nuts that mount with the tank? I could not get the screw remove from it.
They shouldn’t be very tight. They should just loosen with a flat blade. I can’t remember if they have plastic caps on them or not.
I agree with you, very stupid design. Unfortunately I have 3 of these in the house I bought. I was able to replace the full valve once without taking off the tank but I might have to do it again with another. Dunno why they didn’t make the cutout in the back bigger to fit a hand better
What if I want to replace the dual flush unit in addition to the fill valve? Any difficulties there once you have the tank off?
I think it’s pretty straightforward. There is big nut on the bottom. Open that up and it should come out of the tank.
@@mechtrician1 Apparently if you replace the flush valve , you will also have to replace the flush/button unit it as well because the new replacement flush valves are shorter than the original ones, which are now discontinued.
@@Sanjay-pf7mi I used an aftermarket flush valve on the one I replaced and it was a direct replacement. It’s in another video I did.
1001 is helpful
Do not use chlorine or chemicals in the tank there’s the big tip
The video is helpful, but this us still the worst toilet ever designed. With any other toilet, you can easily access the underside of the tank with your bare hands to change anything you need to change. This toilet also has a bizarre way of connecting to the floor.
Worst toilet every designed. I tried making the same replacement yesterday and all the seals were toast. I had to let the customer know the parts have to be ordered.
Fluidmaster 400a better and cheaper wheelchair Larry
toto is such overpriced garbage and terrible design to boot. I have 2 in the house and have problems with both of them every 1 or 2 years. never will buy another.
but first I get the pleasure of doing this repair as well.
having to remove the cistern to replace a fill valve: the definition of OVER ENGINEERED.
Yeah it’s a pretty ridiculous design.
