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.

Customer Reviews

Performax Fill Valve is rated 4.1 out of 5 by 123.
Rated 5 out of 5 by from Simple, Quiet, and Efficient! The PerforMAX Fill Valve is an outstanding replacement for my noisy, difficult to maintain, energy-inefficient alternative toilet fill-valve. The PerforMAX is just the opposite to the components I replaced. PerforMAX was simple to adjust in height to my toilet tank, with clear and straightforward instructions for ease of installation, and operates with far less noise than my previous fill-valve. PerforMAX also has a convenient water refill speed adjustment, ensuring energy efficiency by saving water when refilling your tank and bowl. I am greatly satisfied with this product.

Rated 5 out of 5 by from Easy Installation, Quiet Refill, Powerful Flow I am really happy with my choice to get a Fluidmaster High Performance Toilet Fill Valve. It is made with top quality materials and built to last for years of trouble free performance. I got my new fill valve after my old toilet fill valve was starting to malfunction and was not refilling my tank. My new Fluidmaster PerforMAX Toilet Fill Valve was super easy to install with its easy twist height adjustment to fit my standard 1.6 gallon toilet, then simply connecting the shank to the tank by securing the shank washer between the locknut and hand tighten until secure, be sure to leak test, then connect the refill tube to the overflow pipe and adjust the roller clamp to your desired water savings level. Detailed instructions with pictures are included, along with a toll free customer support number available M-F 5:30 a.m. to 5 p.m. PST. Fluidmaster gives you a 7 year warranty. I highly recommend the Fluidmaster PerforMAX Toilet Fill Valve.

Rated 5 out of 5 by from I would buy this product again Great product

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!
