Flapperless - The greatest thing since toilet paper...With one HUGE caveat!
There is no doubt that the flapperless dump bucket toilets are far superior to the flappers as they provide a stronger flush with less water. However, when they start leaking they make almost no noise...I had to pull the tank cover to hear the very faint hissing and see the spill bucket was full to the rim & spilling over into the tank/bowl very slightly. The hissing was inaudible with the cover on & the leakage was slow enough not to present itself in the bowl...where it did show up was on my water bill which was triple the normal amount. So yes, the flapperlesss toilets are much better but you need to keep a close ear/eye on them & pull the cover periodically to inspect for leaks. The flappers are noisy when they are leaking & often just jiggling the handle shuts them off. The valve that this one replaced was only about 5 years old but the seal/metering pin are subject to wear & degradation...don't find this out the expensive way! The valve is super easy to replace (make sure to flush the line out first if you turned the water off at the wall) & don't forget to swap the little white round restrictor orifice from the old one to the new one. If any adjustment is necessary just turn the thumb screw on the float, no tools are required for the job. PS: My city water company is great & has promised to adjust my bill so it's worth a call if it happens to you.

Works like a charm!
OK, I'm a first time home buyer, been a month in the house and the 6-year old started screaming toilet broke. I wasn't happy as I'm a complete idiot when it comes to home maintenance (i'm learning, but its a steep curve for me). So I was somewhat shocked when I lifted the toilet lid off to see what was inside (really who does that?) Both the wife and I looked at each other and said what the heck is this? So googled the model and found out what kind of toilet and valves work. Found the product here on AMZN. Ordered it, just arrived a few minutes ago. Opened the box (complete intact, not damaged), and yup, same product. So, I went over to the toilet, removed old fluidmaster and replace with my shiny new one. To my surprise. IT WORKED! and it took me as long as to unscrew the old one, toss it into the bin, and screw in the new one. Did 5 flush tests, adjusted water flow to a nice fill rate (who wants slow? If you gotta go, you gotta go!), and I am happy. I can check this off my man card and say yes, I fixed the toilet. I'll be buying another fluidmaster next month to keep as a backup, since I have 2 toilets with this device and I ALWAYS want a spare on hand. My suggestion, find out how many you have, and purchase an extra throw on the shelf, so when it breaks down, your good to go. Thank you, product is excellent, works, easy to install. No tools needed. Lift toilet lid, unscrew old fluidmaster, screw in new fluid master, adjust water flow and place lid back on toilet. GOOD TO GO. This was an excellent experience all around, so 5 stars from me. Remember, I'm a home-owner idiot! So it was easy and simple. When I say anyone can do this, I mean ANYONE CAN DO THIS, heck, a child can do this. next time, the 6 year old will be utilized, give him some basic skills! :)

Perfect
So the flipper valve on our toilet decided to stop working today. The water is very hard where we live and it appears the flipper valve calcified over time. I was able to find a YouTube video demonstrating the same issue and how to install a new one. It was very simple to install and worked for our toilet. Not only was the piece perfect but it was also priced well and Amazon was able to deliver the part the same day โก

Works well, but failed at 1 year
It fits perfectly, and works perfectly, but doesn't hold up well. It's easy to install, and doesn't leak, but the one we bought almost exactly a year ago, was failing. We did replace it with the same unit - it's price is good - but it should last more than a year.

Convenient shopping for this on Amazon.
We knew what we were ordering in this product and therefore, have had no problem as it's an exact replacement. Working fine.

Way to install!
This product was perfect for our toilet tank. We just unscrewed the old one and installed the new one and whala! Easy to install, sealed and adjusted perfectly! Wonderful material and product. Very satisfied!

Super easy and quick!
This now a perfect fit to replace the previous model number 703A5B fluidmaster. Just remember the remove the small white regulator from the old one, this model does not come with it. When your remove the old one, tilt it back to look inside the threaded portion and you will see it. I used a small screwdriver to remove it.

Exactly like the original
This replacement is so unbelievably easy to change out. You wouldnโt need too much skill to get this job done yourself.it is identical to the broken one I replaced and works perfectly.

Itโs nice that Amazon lowered the price!
This was the easiest DIY I have ever done. I rent and the probability of waiting days for a repair was unappealing. Totally worth it! Especially with the price drop while it was I my cart!

Flapperless toilet
I love my flapperless toilet. I changed everything to stop the running toilet and finally gave up and got a flapperless toilet. Now there is only one part and takes seconds to change it. This is a spare in case it is needed. So far 2 plus years in and it is still my spare. A good open for DIYers like myself who arenโt the most mechanically inclined
