Korky is made in the USA and the water fill valve is self contained. I just installed a Korky in one of my toilets. It was easy to install and it works well.

I'm a Fluidmaster gal myself, but it's good to see this comparison. My parents ran a small motel they built for many decades and after my stepdad passed I did a lot of the maintenance. I had 17 toilets in my army of woe. It is amazing the things kids can get stuck in a toilet if they get into the bathrooms alone and are left to play when they get bored on vacations!

Same price for both, so I chose Korky for manufacturing in USA.

I just used the Fluidmaster rebuild kit. Easy install. The overflow tube is now easily adjustable. No cutting required. The tools worked for my 20-year-old toilet. I had to replace the water supply line stop valve. It couldn't shut off the water. I also bought a new supply line that has a metal screw on connector instead of the plastic one. After reading some comments about how the plastic type can and have broken for some people. I wanted to avoid that disaster.

I would recommend buying stainless steel or 100% brass bolts, washers, and nuts. Brass coated hardware is not acceptable, it must be 100% brass. Best not to mix metal types (all stainless steel or all brass) as that can cause a chemical reaction that causes corrosion over time. Doing this will enable one to at least occasionally add some chemical cleaner in the tank without corroding the hardware.

Fluidmaster has all the tools needed to change out everything. Great for homeowners. Thanks

This is a great comparison video! I have installed both of these products in my house -- the Korky kit most recently. I give the edge to the Korky brand just because there's no hacksaw needed for installation, which made for an easier install. I agree that the Korky flapper adjustment is much more complicated than it needs to be. Other than that, however, the Korky kit is a good setup. Ultimately I think either product works well, and if you need a new flush handle then the Fluidmaster option is more economical compared to buying the Korky kit and a separate flush handle. On the other hand, if you don't need a new flush handle, a consideration is if your tank uses two or three bolts to hold it to the bowl. If it uses three, the Korky set might be the better choice as it includes three bolts and washers, whereas the Fluidmaster only includes two.

My experience is that Fluidmasters don't last. I got tired of replacing them every few years and gave Korky a try. As of today, I have never had to replace a Korky.

Replaced the unit with Korky and am well pleased with the installation and performance to date. I liked the ease of adjusting water levels and extendable advantage on the supply waterside.

Ive installed both 4 yrs ago one in each bath.no problems with either.its all about preference, and ability to install

Excellent video, as I just finished replacing an old "arm and ball" float type valve with the Fluidmaster valve you have shown. When I went to the hardware store, both of these valves were available choices and i wondered which one was actually best. As i stated, I ended up purchasing the Fluidmaster and the installation came out fine with no problems, but now I know that the Korky valve probably would have worked okay as well.

This guy answers all questions. Good job sir

Korky all the way Handyman for over 30 years also made in USA Americans supporting Americans

My parents' house built in the late 1960's had the same toilets with no changes for 34 years. I don't understand how they could build things in the 1960's to last half of a century, and now with modern technology it lasts for two years (if you are lucky) and leaks the entire time.

I've never heard of Korky or seen it in the store. I've installed many Fluidmaster valves, and notice that their quality is seemingly getting worse. I just replace one that was 'ghost filling' for no apparent reason. It was only about 3 years old. Maybe I'll try a Korky if the situation arises again.

Very thorough comparison via actual installation. Well done. I found this quite useful.

Had the exact dual flush Fluidmaster that started ghost flushing after 2 years. Checked out everything and the problem continued. Had to replace it with a universal Fluidmaster replacement.

Korky any time of the day! Made in USA not China like Fluidmaster.

Had both, Replaced both brands within a year. Korky because it would squeak when shutting off, the fluid master because it leaked into the tank.

I went with the BrassCraft version of this style. It has a ten year waranty. The first one started failing after three years. It was replaced under waranty but it took months. Now the second one is doing the same thing after about another three years. The problem is the rubber diaphragm starts swelling from the chlorine in our municipal water. This prevents the fill valve from shuting off and the tank overflowing down the overflow tube.

My many thanks to you, Sir. I wish you could make one of these thorough video comparisons for everything I need to make a decision to buy.

I used the fluid master kit and it came with all the tools i needed really nice

Excellent. Thank you. Sounds like the Korky is a slightly better bet.

If your toilet has 3 bolts holding the tank get korky or extra hard ware for the third bolt with fluid master

An excellent comparison in detail and tips on installation and answers on "What if" questions in procedures. Well done, Thank you.

I use to like Korky because it was easy to install, but it is always getting leaky after just a few months. Now I'm trying fluidmaster.

I noticed that Korky has 3 bolts and the other has only two. A my Kohler bowl takes three. Just puting that out there.

Just installed a fluid master fill valve today. Mine came with the a bowl/tank dial like the korky in the video, not a roller valve. It’s super easy to use

On the toto toilets I have, i had to replace the flush towers with the new toto ones as the older designed leaked like crazy. Swapped the fill valves too

I've installed two of the Fluidmaster kits recently, and used a tubing cutter to cut the flush valve tube. It's easier than using a hacksaw, and makes a clean cut. The Fluidmaster has brass bolts, and the Korky has stainless steel bolts. That alone justifies going with the former. I also don't trust the Korky overflow tube not to leak. Adjustable? No thanks.

New installed Korky didn't work leaking tossed it. Installed Fluidmaster in 5 min. perfect.

The Fluidmaster is the best because they last longer/take longer to break down. Korky is junk and they break down fast. I've removed a ton of each of these and I've found that Korky rubber starts getting sticky and flaking apart after a short while.

Thank you so much for posting this video. This information is worth more than gold. 🌹

Beware Kohler and their proprietary tank-to-bowl gaskets... There's a hot place waiting for that designer/engineer/marketer!

Mine was overflowing since last night was making noise , shut off the valve went to Walmart got the fluid master same that was In it, took me like 3 minutes to replace super easy and cheap only like 11$

Thank you! I have a toilet that is constantly refilling this was helpful

I bought Korky kit, but regretted. The water tank leaking is the major issue. Gasket is so thick , and the water tank is easily pushed to one side. I finally used the old gasket to solve the issue.

Korky normally lasts about a year from my experience. The fluid master several years. They both work great until they stop.

Thanks for great info. I'm confident I can do this myself!

I liked the video and all the work that went into it. What I did not like and was disappointed at the end is that there was no 'concluding summary of thoughts', in other words. After all this work to get to know them, here is which one I would buy if I wanted this out of it, here is which one I would buy if I wanted that out of it. It felt like a cop out a politician would do at the end which made mis mistrust the whole clip.

I replaced my water fill valve with the Fluidmaster, and it lasted 1 1/2 years until it quit working. In looking at reviews, it seems both of these leave a lot to be desired in terms of reliability. Do you have a higher quality recommendation?

Korky bowl fill is less complicated. More quiet. Korky.

Just installed a fluid master and it didn't have that roller lock on the hose. It had a nice valve to adjust the flow.

Been a plumber for over 20 years. Fluid master is way better. The korky one doesn't last as long nor is it as easy to repair. Stick with fluidmaster

This is the second one for the basement bat. kzfaq.infoUgkxOuLt8IL_GxhhaK8DBuKEL-zV0UJVpWZn , works great

Very nice explanation, I learned something new here. I never heard of korky until recently when looking at toilet sealing rings. I didn't want to mess with the wax ring.

Korky is my friend. He wins

Like your video style! Subscribed, and went with the Korky!

Wow Nice comparison. Great video Very thorough Liked and subscribed

Great comparison video

So, you still never said which one was better.

When changing a fill valve is it always good practice to stay with the brand that needs replacing??

I have used both. The FluidMaster is more difficult to adjust. Also the Float gets stuck on the pipe, even though it is plastic. Don't have that trouble with Korky. No moving float with Korky either. Easier install and less trouble than FluidMaster. 👎 Korky 👌 always.

Your video is very detailed and informative! I have a hNdle problem on one toilet and the overflow valve problem on another one. Can I buy both these products, switch the parts and use either on either toilet to fix the problems? For example, can I use korky for I like how the overflow valve adjustment is easy but use the handle from the other one? Thanks again

KORKY - Made in the USA. That's all I need to know. I refuse to buy anything made in China.

Thanks for an excellent video.

Well done! I used Korky. Please address the correct way to join the tank to bowl. Some say metal washer then rubber washer. KWIM?

Good Video! I think I learned something..Thanks!

Awesome review!!💯

So great you did this comparison. What I was interested in was to find out which one has the sturdier, longer lasting flappers. Fluidmaster says longer lasting on their package, and their rubber is thicker comparing to the other brand that's thinner and softer. I haven't used Korky yet. Have you noticed anything? Thanks!

Thank you brother

I have the identical original Flush valve and flapper that you started with in the Video. Can I install the Fluidmaster 400H-002 model and keep the original flapper? It is working fine and I don't want to take the tank off.

I have 2 American Standard toilets both equipped with Fluidmaster kits by the toilet supplier. After about 2 years following install they both leaked. Cleaning the tank outlet, flushing the fill valve and adjusting to optimum settings did not help. 😨

I will switch to Korky 100 %

Korky all the way.

I have tried both and they are all pretty hit or miss. Neither has much advantage in quality or durability. Expect to work for 1-2 years and buy which ever is cheaper at the time…

I replaced mine with the Korky but don't like the slow refill. Don't remember if old refilled faster nor brand but I wish they made one that refilled faster.

I can tell why ghost flush. It’s the tube … it’s to far down the flush valve and siphoning. Use supplied clip for tube so it’s above flush valve! Your welcome 😊

Awesome video!

Thanks man

I really don't like how the korky toilet kit, comes with that thick rubber that causes my tank to rock, now I got to have that kit taken off and replaced 😢

You’re speaking my love language

Not a fan of the Korky compression gasket...had to tighten it down again...two man job to push the tank down while tightening the bolts...

good video

So….I guess my question is after watching the video That states the question in the damn video title….WHICH ONE IS BETTER???? For real bro? Legit wanted your opinion at the end and got left high and dry. Wtf…

How do you stop a Korky Fill valve if the toilet is about to overflow? We used to raise the ball on older valves as kids or pull up the float on newer Fluidmaster fill valves. How would you stop the water flow quickly on a Korky Fill valve? I know the valve coming out of the wall is obvious but can it be stopped quickly without using that valve?

Interesting!!!!

The Fluidmaster 400A has an easy adjustable height pipe so I don’t know what this guy is talking about.

Good Video. Yep I saw it dude, your tank to toilet gasket, is just like mine is black and thinner than the bigger orange one that comes with the fluid master, it causes my tank to move side to side with some pressure, I kept the original to bring back to the hardware store to find a match in case that big orange one starts to leak. Also your flush tanks were really clean, mine had old bits of rubber and some grime on the sides so its a good time to wash it out really well. Looks like you missed comparing the handles. The Fluid Master (the one I just bought) is cheap and you have to bend the plastic lever to the same shape as the original it really is a piece of junk so I used the original. The Korky it looks like real zinc plated metal or is it that your original flush handle on the Korky? For me with zero experience it took 2 hours to replace because the lock nut from on the flush tank under the gasket was frozen on from never being changed in 16 yrs. I had to cut it off with a cordless jigsaw (a tool everyone should have). Also the water line now has a S shape because the fluid master fill valve stuck down lower than the original and I was not going to cut my water line or the threaded fill valve. Also Fluid Master recommends replacing the hardware connection on the water line if its over 5 yrs old, I just used the original old ones (I am saying no to trips to the hardware store).

Which one fills the tank faster ?

Starting now hoping I don't have to buy a saw

La marca no es korky es lavelle

You keep stating that the old trim inside the second toilet you show is Fluidmaster. It is actually not. State your info correctly.

warranties are blatant scams

2:05 that is not a fluidmaster that's a Hydroclean toilet valve For the people that believe that was a Hydroclean toilet value at 2:05 👇

What a joke! The original valve was still good, the fill hose had just worked its way down into the fill valve tube which any plumber knows causes a syphon😂! For $20 though, it was probably time to get rid of that 1960’s ball float anyway. Nice clean cut on the fill valve tube btw, looks like you could butcher a cow with those jagged edges. 20 seconds with a file would’ve made it look so much neater for the customer. Thanks for the effort but a waste of time to watch this video

Fluidmaster is junk that has to be consatntly adjusted.

GREAT VID
