instructions say to raise water level turn clockwise & counter clockwise to lower but i can't get screw to turn either

Asked by: Anonymous
I had the same problem until I slipped the plastic ring up on the lower plastic tube, then you can adjust the tube up or down.

will the performax work on a toto toilet,which needs high flow to refill bowl?

Asked by: Anonymous
Not sure what you mean by high flow. I found that this valve refilled somewhat slowly and was therefore pretty quiet.

will the Fluidmaster Performax High Refill Rate Fill Valve fill valve work in an American Standard tank 4072?

Asked by: Anonymous
I don't see why not. It looks like a pretty normal tank and this valve should fit just about any toilet.

Will this valve work with the Icera one piece toilet?

Asked by: Anonymous
Is the connection to the water supply external to the body of the toilet? (In other words, does the water supply connect to the bottom of the tank OUTSIDE of the side panel?) If so, the Fluidmaster valve should work fine.

Performax Fill Valve is rated 4.1 out of 5 by 118.
Rated 5 out of 5 by from 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...... ;->.

Rated 5 out of 5 by from Lightning Fast Fill Time! I had to purchase a new fill valve for my toilet that was taking 4 minutes to fill. Flushing the original fill valve did not fix my problem, so I needed a new unit. My old valve also failed to shut off sometime which caused my water bill to skyrocket. I came across the PerforMax valve and decided to give it a try, because I was sick of messing with my old valve and waiting 4 minutes between flushes. I installed this unit (very easy!) and timed my refill time from the second I pull the handle. It took 45 seconds from the time I touched the flush handle until the toilet went silent. Amazing! I'm probably going to replace the fill valve in my other toilet with a PerforMax as well.

Rated 3 out of 5 by from not as good as basic Fluidmaster Like other reviewers, when i needed a replacement fill valve, i thought the Performax would outperform the basic Fluidmaster but i was wrong. The Performax worked but louder and much slower fill time compared to original fill in my American Standard Cadet 3 toilet. It bothered me enough that i replaced the Performax with basic Fluidmaster and it was quieter and filled in 1/3 the time. Buy the basic 400a, not this version!

Rated 1 out of 5 by from Doesn't fit Kohler toilets 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 1 out of 5 by from Not Worth the Extra Money Purchased this "upgraded" flush valve for installation in an existing toilet in a remodeled bathroom. Two other toilets already had the "cheaper" Fluidmaster which work fine but I thought I'd install the upgraded one since the bathroom was remodeled. Well, what a waste of money and time. It seemed as if the toilet was refilling slowly and making a great deal of gurgling noises. I timed the refill at 1:57 minutes, then checked the other Fluidmaster toilets in the house and they refilled in 55 and 57 seconds, they were quieter too. Purchased the "cheaper" model at Home Depot and replaced it in the remodeled bathroom. refilled in 50 seconds, no gurgling and much quieter. Don't waste your time or money with this upgraded one, go for the "cheaper" (by about $4) Fluidmaster.

Rated 4 out of 5 by from Good but not great relative to other Fluidmaster valve I give this valve 4 out of 5 stars because it costs a few dollars more than the standard Fluidmaster 400A flush valve but doesn't offer any huge improvement that I can detect. My toilets have approximately 3.5 gallon tanks, and the one with the standard Fluidmaster valve and the one with the new Performax valve both take about 90 seconds to fill. It's not that much quieter than my older, standard Fluidmaster flush valve. I do like the way the Performax valve allows adjustment of the amount of water entering the bowl while the tank fills, but this is the only benefit I could identify relative to the standard Fluidmaster 400A valve. For what it's worth, I installed a Fluidmaster Click Seal supply line at the same time I installed the refill valve, and it was much easier to install than the old supply line, which required a wrench.

Rated 3 out of 5 by from 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 out of 5 by from 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?
