Rated 1.0 out of 5.0 by John Plastic float fills with water and doesn't float
After a few months of use valve began to run constantly. I noticed that the float was submerged and filled partially with water and did not float enough to shut off the valve. There are two holes in the bottom of the float and one hole in the top. Two halves of the float merely snap together and are supposed to be completely watertight which is an absurd expectation. The plastic itself has some buoyancy but not enough to shut off the valve, and why design a float such that it fills with water? I'm now amazed that the thing ever floated at all. I suppose the people at Fluidmaster think this is a robust design for a plastic float mechanism. I do not. Planned obsolescence?

Rated 3.0 out of 5.0 by Vanna Too slow
Was very easy to install, but it fills the tank at an excruciatingly slow rate. I timed it at 2 minutes 20 seconds. It was not my supply line because I took the fluidmaster out and replaced it with another fill valve and the tank filled in 45 seconds.

Rated 1.0 out of 5.0 by webslog High-Efficiency? For Whom?
This thing is garbage. Used this is a replacement for an actual Toto Fill Valve because I'd had good experiences for Fluidmaster products before. Mistake.
I don't know what "High-Efficiency Toilet" means, in this situation, it means incredibly slow fill (90+ seconds versus the Toto OEM's) and noisy to boot. I've done a line flush and still no relief. Out of desperation, I pulled the whole thing out again and found crammed into the bottom of the fill valve, where the water line enters, a soft white rubber stopper with screw threads on it. It appears to slide upward when the water pressure from the inlet is above some amount and dramatically reduces the water pressure sent up the riser to fill the toilet. I'm looking for info on line to see if I can just pull the rubber thingy out. Failing that, I'll just pony up the extra couple of bucks and buy the OEM part.
Save your money.

Rated 5.0 out of 5.0 by oscar Just what we needed!
We needed a flush valve for an older toilet and this one worked very well. The height adjusts to 15", which allows our tank to fill to higher water level, enabling it to have enough water in the tank to flush properly. Most valves only adjust to 14", which didn't work with our toilet. Easy to install.

Rated 5.0 out of 5.0 by Breeze It does the job.
Installation was easy taking only about 5 minutes. I used this valve to replace the old fashion float valve with the huge ball. I would have rated 5 stars for quality but honestly, most plastic moving parts seem fragile however I must add, it is better than metal submerged in water and I was not concerned about breakage during installation. Actually, I was more concerned about the shutoff valve. Value? Do the math....It took a trip to Home Depot, 5 minutes to install and it works perfectly. How much would YOUR plumber charge? If you have seen one toilet, you've seen them all but I included three pictures to illustrate how simple this is...... ;->.

Not recommended for Kohler toilets - I have a 1-piece toilet. Stick to the Kohler fill valve even though it's much pricier. Was very loud too.

Rated 3.0 out of 5.0 by JamesTheDIYer This is an adequate but slow filling plastic valve
Fluidmaster PerforMAX Fill Valve is: 1) Plastic; 2) Not all that quiet; and 3) S-l-o-w to fill the tank. The fill tube has a small inner diameter (opening), even without their clip installed. It does the required job but takes around one and one-half minutes to fill our smaller toilet's tank. It depends on what you are looking for. If you want quieter filling than the fast-filling valves, this valve will do the job. However, it accomplishes its quieter sound by slowly filling the tank through a smaller tube.

Rated 1.0 out of 5.0 by VicL Very Noisy, Slow to fill
I replaced my old basic Fluidmaster with the Performax Fill Valve thinking it would be more quiet and fill faster then the basic model, I was so wrong! The bathroom is located in my master bedroom and when the toilet is filling, it was so noisy I actually could not hear my TV! It is also a lot slower to fill than the basic fill valve. After 2 days, I couldn't take it anymore and switch back to the cheaper valve. Back to almost silent and quick fills. Definitely not the "Quietest" as advertise.
