Easy DIY Fix For A Slow Filling Toilet 

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

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

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!

This is a fix worth remembering. Thanks!

Plumbers grease helps the valve seal last even longer

Big thank you! This was exactly what I needed and it was cheap and easy. Keep up the good work

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.

Thanks - just did this 5 minutes ago for my elderly dads downstairs toilet. Worked like a charm!

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.

Nicely done! Just replaced a fill valve this weekend. Wish I knew there was another option. Thanks for the video~!

Very good instructions. Thank you! I'm going to try this tomorrow morning!

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.

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

Good vid. Also, while removing and reinstalling the cap, it helps to hold up the lever as you do it.

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!

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

Such a simple and cheap solution to my problem. Worked just perfect. Just bought two more for the other bathrooms. 2:52

Great demonstration.😊😅

You’re the man. Thanks

Thanks for the video!

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.

Oh my! I'm about to do this for my parents' toilet. Thank you so much.

Thanks!

THANKS 👍😁

That’s a great tip, I will try this out thanks

Well done.

Thank you 🙏🏻 for sharing this information 👏👍

Thank you! This was exactly the issue. I didn't even need to replace it, I just had to clean it.

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.

Awesome! I had no idea!

Another great video, Scott! Excellent! Thank you.

Good stuff.

Good job

Shooootttt!!! I didn’t know you could replace innards like that!!

Cool, thanks !!👍

Once again, more great useful info. Thanks Scott! JimE

Thanksso much brother

Thanks. Fixed my toilet. There was a seal that fell out to easily when I removed the cap. Cleaned everything, put it back together and voilá, running like new!

Thanks a lot ,

I'm going to try this because I have a very slow filler. But I also have an occasional running problem when the hook on the flushing lever gets stuck in a horizontal position instead of in the usual vertical position.

thank you very much. this saves a lot of money.

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

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.

You are the best thank you

Thank you 1000%

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!

That was helpful.

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!

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.

Good fix if it works ,usuwlly better changing. The float if you can get at it easy

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

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

But sometimes u need some loud noises to cover up other noises

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

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.

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.

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

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?

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.

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

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.

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.

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! 👍👍

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.

Is this a standard size? My toilet innards look the same as yours but I don't know if this exact same size valve seal will work? Thanks for any guidance.

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

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 😂

Can you give any ideas why a bathroom faucet would have low water pressure?

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

With the cap off, I turned the water on to flush the line, but it only trickles out even with the main supply wide open. What should I try next?

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.

How do we know what series we have??

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!🤣

What’s the best thing to do when a float won’t come all the way to the top to shut off the flow of water unless nudged up by hand? Adjusting the float vertical position with the screw didn’t help and neither did a cleaning. Replace the whole fill valve?

👍🏿

got one that pulses... so weird. it's one I've not experienced in over 50 years of using toilets.

Can you adjust the water level in the bowl, either higher or lower?

My wife flushed the toilet n tank was not filling a half hour later. Water was going in the fill tube though. Seems flapper not centering on gasket

Do you come with the fix😂 Cuz I just know with my luck when I try to turn that thingy ma Doogie it's gonna break into a million pieces.....and I know you can't cuss the parts back together again....in the past I've tried😂😂😂😂😂😂😂

Could you not soak the seal in CLR and clean it then reinstall rather than replace it?

My toilet sometimes continuously runs a small amount of water. If I push the float down couple of seconds it usually stops. I have assumed debris gets trapped under the seat. Maybe I ought to take off the cap and let water flush it out like you did. We have old galvanized iron water pipes.

When my toilet kept running it always seems to be the flapper. That's a $5 part and only takes a minute to change out.

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.

I replaced mine because the calcium deposits make the float stick and continuously flow the water aka the water bill.

I would have loved to have seen if the debris you flushed out would have made a difference before replacing the seal. Good old troubleshooting tactic... change one thing at a time.

Wow, that is a fast-filling toilet. Almost looks like the video was sped up!

If I drop in a cake of soap into the tank, the tank starts to fill very slowly and only after a few minutes? Why is this?

That's a cool trick. But to be honest, I don't even bother trouble shooting this. Fill valves are ten bucks and it literally takes 5 minutes to replace.

It's cost about almost $10 change the whole stupid thing for $12
