I will walk you through a simple fix that any homeowner can perform to quickly fix a toilet that fills the tank slowly. The majority of tanks should fill in 30-45 seconds but mine took over 5 minutes so I knew there was an issue. I have found this fix to be the same solution to other common issues such as a toilet that continues to run or when you hear a loud whistle at the end of the fill cycle.

Flushing the toilet hasn't been an issue since my kids were little. As a great-grandma that has been many years. Lately I have had to plan that flush, before the 30 minute dog walk was just about right for the refill. It's when I got back from the walk and it was still going that I began my quest for a repair. Here comes KZbin, and your easy fix. I watched it, convinced even I could handle the repair. I ordered the seal using your guidance, and received it quickly. Then I stared at it for a few days, wondering what I would do if the repair was harder than I thought. Finally the toilet forced the issue, taking an hour to fill up. I made my backup plan to recover in the event of a fix failure, and started working on it about 30 minutes ago. I flushed, turned off the water, lifted the lid placing it safely aside. I turned the thingy and struggled to get it off. Why? I was making it much harder than I needed to. Stopped myself, and started again. It came right off. There was the little seal! It came right out, and I put the new one on being careful not to bend the pin. :) Cup in hand and held upside down, I turned on the water to flush out that little pipe. Turned the water off again, put the thingy back on, turned it to click, and attached that little tube. Wahlah! It works! Thank you for your very concise and simple instructions. You saved me a ton of money by not calling a plumber, and I now have confidence to try the next fix for a toilet fail in the future. Oh, and it took 5 minutes for the fix, 25 to write this!

[@TooLazyToFail]

Great job, Mamaw! I called my great-grandmother Mamaw, and she was every bit as capable as you seem to be! I love KZbin for this stuff so much.

[@markkempton4579]

I had no idea this was a thing. Very excited to try. We have a slow filler. It may be because it was sold as a "quiet" fill, but it's become so much slower than it was previously. It takes at least 90 seconds to fill the tank and bowl.

[@jilll.4835]

$2 later and toilet went from taking about 8 or more minutes to fill to about 30 seconds. AMAZING. Thank you SO much!!

@@EverydayHomeRepairs I watched the video when you replaced the toilet handle. What store did you buy the Fluidmaster toilet handle from?

[@gregpochet4812]

I just buy the whole new floater system for ~$12! didn't know you can replace the seal inside for a lot less. Thanks!

[@EverydayHomeRepairs]

You bet!

[@KameraShy]

Takes a lot less time and work, less mess.

[@docferringer]

The nice thing about the Fluidmaster line is they are entirely modular and serviceable. If you have a toilet that is a pain to get a good tank seal on when you do a full replacement (say, older ceramic with uneven glazing where the o-ring sits for instance) you can leave that part alone and replace just the part of the stalk that is up in the tank. If you look at the video around the 5:20 mark you can see a plastic locking ring that lets you adjust the height of the whole assembly in your tank....or take old assembly out and put on a new one. All without compromising the outer tank seals.

[@NSFWHarold]

You just saved me the hassle of replacing the whole kit. One of mine has been doing exactly this for about a year. Now I don't have to climb under my toilet. Easy peasy. Thanks brother!

[@jaym1244]

I love your attention to details. One of the reasons I love your channel.

[@jimm6339]

Thanks. This was a timely video . In the past I have replaced the whole valve, pricey and time consuming. This was a quick fix for toilet.

[@rickcormier9160]

I put in the Korky valve with good results. My toilets each use 3 gallons of water for each flush. I filled a slim water jug with water and used it to displace 1 gallon of water in the tank. Now I only use 2 gallons of water per flush and the tank refills in a third less time. The toilet still flushes great. I did this mostly because of frequent water outages and needing to store a few 5 gallon buckets of water for emergency flushing.

[@Dave-ld3dr]

Ironically I just did this a couple of weeks ago.I put a clear glass over the top of the fill valve while turning the valve back open a few times.While the tank was empty I poured some CLR down the fill valve & left it there for about an hour then flushed the fill valve out again just to be sure there was no lime or calcium in there blocking those vents.Everything works great & the CLR in the tank cleaned everything nice.You could probably just use vinegar.I almost bought & replaced the entire fill valve before changing that one part.Good video.

[@rootpower8664]

I'll definitely give this a try, so far I've tried every little fix out there like playing with the adjustment screw and cleaning different pieces, so this will most likely do the trick. Thanks for the video!

[@EverydayHomeRepairs]

You bet, best of luck!

[@moboutmen]

Well presented. New gasket is the key. Dont just open and clean.

[@Shootsmith]

Plumbers grease helps the valve seal last even longer

[@rzh3443]

Yes , did this exact repair to one of my toilets a few years ago. That diaphragm is pretty much the whole operational deal to the Fluidmaster fill valve. Very reliable and a real bargain for the long run.

[@Noname-bg5nh]

This is different from most slow full vids I’ve seen and tried . I flushed out my fill valve and checked to make sure the little tube from the fill valve to the bowl fill valve was clean and also empty but those didn’t fix my issue. Ima try this now and follow up after!

[@grassrj]

Thanks! That solved my exact problem!!! Would have bought the whole kit.

[@EverydayHomeRepairs]

[@whattheschmidt]

Well this is great timing. I have had mine have filling issues, sticking and loud for a month or two now - I didn't care because I'm going to remove the toilet soon to redo the floor of that half bath. But, I will check if it's just that seal instead of needing to replace the whole fill valve! Thanks!

[@whattheschmidt]

Update - I replaced it just now. My shut off valve (gate valve) worked well enough (very slow drip) and I put in a Fluidmaster 400 that I bought 4 weeks ago from Amazon. Easy replacement job. I could not get the top off of the NuFlush fill on the toilet, I couldn't twist it off. Didn't matter anyway, I didn't have the replacement seal for it. All set!

[@mordecai98]

Thank you! I cleaned mine out, and it goes out the overflow valve now, but the tank still fills very slowly.

[@57haldir]

I have tried this dozens of times and it has never solved any problem. I’ve even tried to replace the entire cap. I don’t know why it doesn’t work for me.. I appreciate you showing us how to do this and I’m glad it was successful but I always wind up replacing the entire valve.

[@Joe-xy3vy]

Mine was slow due to debris behind the shutoff valve. I often find chunks of gaskets and other debris in my feed. I assume it's because of backflow from my neighbors.

[@AndyNav1]

Thank you for the video. I just replaced the seal as you show. The leak is resolved but the fill takes forever to finish. Any guidance is much appreciated.

[@oldtimefarmboy617]

When I was a kid and played with dinosaurs, the fill valve use to take up to 3 minutes or more to fill the tank up, and that was brand new and good working order. Even in a family household, it was rare that a toilet needed to be flushed two or more times in a row.

[@mattlco]

Flush time went from 3 min 36 seconds to 1 min 16 seconds. Well worth the $2 and under 10 minutes investment!!

[@rcmrcm3370]

Fast fill can create water hammer, similar with solenoid valves on clothes washing machine.

[@KameraShy]

If you have water hammer, that needs to be addressed separately. Turn the water off, turn on a faucet at the lowest level and let it drain out entirely. Usually fixes the problem.

[@TheSouthIsHot]

Earlier this month, I replaced all parts in both toilet tanks in Mom's house. I had been dropping bleach toilet tablets into the tanks for several months when she and I noticed that pieces of rubber were floating around in the bowls after flushing and water was beginning to leak everywhere. The bleach toilet tablets had disintegrated all of the rubber parts inside the tanks!😭 I was so MAD!!!😡 I bought Korky kits for the replacements and on the instructions it says do NOT drop cleaning tablets into the tanks! But on the packaging of the bleach toilet tablets, no where does it say that the product can destroy the rubber parts inside a toilet tank. I want to sue!!! PS: I'm a 54yo 5'2" female who had never replaced toilet parts before. (This includes removing the tank from the bowl.) The instructions are easy to follow and manufacturers have videos on their websites. So don't be afraid to give it a go, ladies! Read the instructions thoroughly and watch the videos before you start. You might hit a few snags along the way but you'll figure it out and learn from your mistakes and fix them. PPS: Thank you for this great video. Half the problem is figuring out what the problem is!🤣

[@KameraShy]

ALL toilet tank parts contain some rubber. Even without the "additives" they do wear and disintegrate.

[@jeffreybaba4155]

I bought a brand new fluidmaster unit like that and it's still working slow. But I recently had a new water line put in so there might be some grit or something inside there.

[@rickkane8043]

About the one it doesn’t fill if you don’t touch the fill valve inside the tank. Sometimes our toilet doesn’t fill and I need to shake the handle or open te tank cover and touch the fill valve before it fills

[@paulklote4845]

Could you do a video on replacing the fill valve parts in an older Manchester stool?

[@KameraShy]

I used to use the metal Manchester valves and was always skeptical of the plastic Fluidmaster. One year I took the plunge and installed a Fluidmaster. It has been years and it has worked just fine. I did replace the seal once and it took all of 15 minutes, mostly because I wanted to make doubly sure I was doing it right. Next time probably 5 minutes.

[@morganw02]

What are your thoughts on the adjustable flappers? Bought a house with a couple already installed, but they seem to make it harder to get the flush pressure set.

[@siriosstar4789]

The most powerful flushers were the old models where the tank was up on the wall against the ceiling . i had one of those in an old house i was renting back in 1969. pull the chain and step back .😂

2:04 -- Bold of you to assume my on/off valve can be turned without snapping it off immediately and flooding the entire bathroom in my old ass house 😂

[@jaewok5G]

*your mileage may vary

[@whattheschmidt]

Of course my toilet in my half bath (which has this exact issue) is the ONLY shut off I haven't replaced in my house. It's an old gate valve that shuts 98% of the way though. Close enough? The ones under my main bathroom sink didn't work - when I tried shutting it off it instead sprayed the hot water out at me :).

[@matthewmosier8439]

​​@@whattheschmidtRun a hose out of the sink cabinet to a pan of some sort if you have to. That will give you time to do work. That or turn it off at the main valve, outdoors. Used to install appliances and shut off valves can be a real problem in that profession

[@KameraShy]

People should exercise all water valves periodically. Lack of exercise is why they become frozen.

[@whattheschmidt]

@KameraShy doesn't help when you buy 50 year old houses and the previous 4/5 owners did little to no maintenance!

[@TonyC93]

Do you have a video on how to make the toilet filled up with more water when its to low

[@KKemp-bt6nl]

Great video, thanks! I replaced my fill assembly, and the toilet bowl only fills about 1/4. Any advice for getting more water into the toilet bowl?

[@EverydayHomeRepairs]

Check that fill tube going into the overflow tube. Is the water going into the overflow tube?

[@dalemihocik4732]

Followed your video precisely and even flushed the supply line and still the tank fills slowly. Is it likely the fill valve itself has some internal defect causing the slow fill? Can't imagine were else the problem comes from.

[@peterbergeris6510]

Replaced flapper. When it is filling too slowly, I move the flapper so it's more in the center of the tank seal n all is ok. Would it be the tank seal or gasket at the bottom of the fill tube or what you suggested here in the video.

[@sapelesteve]

I have this exact slow fill toilet problem. However, I have a Kohler unit not a Fluidmaster. Will this seal work with the Kohler? Great DIY video! Thanks! 👍👍

[@EverydayHomeRepairs]

Depends on the Kohler fill valve. Take a look at your fill valve and do a quick search for Kohler Fill Valve for the specific model. Some of the Kohler valves are very similar to the FluidMaster 400 series and the seal might be interchangeable.

[@andrewpolasek5524]

If your toilet is still slow to fill after doing this repair, there is a rubber water restrictor in the bottom of the Fluidmaster fill valve which can be removed with a pair of needle nose pliers.

[@TomMcDonaldatYahooDotCom]

How do we know what series we have??

[@sharonperry6161]

Hi, I just watched your video. I had already replaced the fill valve and my fill tube has the stopper on the bottom of it and I replaced the seal on that also. My water level in the back of the tank is not quite at the level it was before I replaced the fill valve. My handle doesn't have a chain connecting to the fill tube. I need guidance.

[@yupsir791]

My 👀 😳 @ 2:05. I had the valve snap on me, turned a quick 15 minute job into another run to the store. . .

[@richmargadonna2155]

I have the exact same fill ass'y in my slow filling toilet, but my shut off valve is stuck and won't turn. Tried the WD40 and other penetrants but this thing is stuck. Anyway, it looks to me like it's one of those chrome valves that is made with a chrome inlet feed tube attached to it. I've seen them before. There's a piece of 1/2" copper that comes out of the floor and sticks up less than an inch. The chrome tube slips over the copper pipe and is soldered in place. So, I figured a nice short cut would be to cut the chrome tube up near the valve, discard the valve and put a new 1/4 turn valve in its place using a compression fitting type valve. But, since the chrome tube slides OVER the 1/2" copper like a sleeve, it's much thicker and I can't seem to find a compression fitting that fits over the chrome tube. Do they make a compression fitting/ valve to fit over the chrome tube or am I stuck with a soldering job that I don't want to do? OD of the chrome tube is .685. The helpers at Home Depot have no idea what I'm trying to buy. Thanks, Rich

[@patrickursomanno8861]

What the yellow thing in the chain going to flap? Soes that make it close quicker, mine does, was thinking of cutting it off.

[@EverydayHomeRepairs]

Suppose to help delay the flapper closing to empty more water out of the tank. Some times you run into an issue where the flapper closes too fast and you only get a partial flush. No bueno 👎

HELP NEEDED - Advice Anyone please: I got a odd issues with the two Fluidmaster Toilets' in my home. Toilet 1: When I flush, nothing fills up. So I have to pull off the tank lid and once I turn the whole Fill Assembly about 1/4 turn Anti-Clockwise, the water starts to flow fine (float is already down, valve is just not coming on)! But then once the tank is filled up and the float rises up all the way, it will never stop running (full blast) until I manually turn the whole assembly 1/4 turn back in a Clockwise way - back to where I started. So the whole thing works: but only if I manually TURN the whole Float/water entry pipe RIGHT to it to start Filling AND then turn it, and then turn it back to the LEFT (Clockwise) to make the Water Fill Cut off. I don't touch anything else. Toilet 2: On other toilet, I often have to open the tank and PUSH Down slightly on the Float to get the water to start filling up. The float falls - but it appears not to go the last 1/8th of an inch so the valve will turn on. My own thought - perhaps I can just tape some pennies in top of the float to get it fully fall - but I shouldn't have to. Honestly, I am fed up with Fluidmaster and just want the Old Floating Ball and bar I can bend to adjust tank level and to operate my valve on/off...Those old ones worked for DECADES, so of course the Scammers stopped making those and give us FLUIDMASTER to replace every 2/3 years!!

[@dottier3145]

I’ve got both problems, one toilet runs all by itself. Came home to water out into hallway, and neighboring bedrooms. had a plumber fix it, but it still “runs by itself. And another toilet that’s slow.
