Rated 1 out of 5 by from Cheaply Built Our 3 year old home cam furnished with these. We had 1 toilet's Fluidmaster fail 2.5 years into ownership. It took about 4-5 minutes to fill the toilet. When I replaced that unit I went from one issue to another. The brand new Fluidmaster replacement unit makes a loud noise when filling up. Figures it's in the bathroom right by my childrend's. More recently, 3 years into ownership, we had yet another toilet's Fluidmaster fail. This time it was making a high pitched squeal noise. I ended up replacing our 2nd toilet with a different brand that was $5 more. A much better decision as it fills fast and is quiet.

Rated 4 out of 5 by from Very Easy to Install, Works Well but... Though it looks almost identical to the fill valve that came with our 10-year old Kohler Santa Rosa toilet, it fills faster (good) but is noisier (bad) than the original. Installation was super easy and the toilet was working again in about 10 minutes. I would have preferred a quieter value, but oh well.

Rated 4 out of 5 by from Simple and works Replaced the fancier one I had that wouldn't stop running with this model. Went in quickly and easily. Unlike the instructions said, I did slide up,and loosen the height adjustment ring before setting the correct height and then slide it back into place. It worked fine (at least it's been okay for 30 minutes) . As noisy, or quiet, as my old one. Only suggestion to,the manufacturer is to indicate in their instructions which way to,turn the water level screw.

Rated 4 out of 5 by from Noisier but works great This went into a 6L American Standard, worked like a charm and was a breeze to install. The only complaint is that it is noisier than the one it replaced.

Rated 1 out of 5 by from Spend the extra money! What a P.O.S! I bought a toilet 5 years ago and had one of these garbage fill stacks. It made it to around month 4 before the diaphragm crapped out. I have replaced it 3 times since then and now have to replace it again as it just keeps running. What happened to manufacturers pride? My grandfathers had ballcock systems that had barnacles on the float and they still work 100% Spend the extra money away from Fluid master!

Rated 5 out of 5 by from Does the job! My Korky started leaking and all the Youtube fixes didn't work. Bought a new Korky and amazingly it still leaked. Gave this Fluidmaster a try and voila, no hissing or leak. Yes it's a but louder but who cares. The noise ends in a few seconds. Easy install. Very pleased.

Rated 4 out of 5 by from Why having to buy the whole unit Very good quality generic toilet valve with clear instructions. The price is a little too high. In most cases you have to buy the whole unit when in 90% of the time the only faulty part is the black rubber stopper which shouldn’t be more than 2 bucks.

Rated 5 out of 5 by from Great product! We purchased this yesterday...after researching online as to why the toilet would run when faucets in the house were turned on. Once we installed it the problem stopped! Instructions were easy to follow. So far very happy with this product!

Does it allow me to adjust amount of water going into bowl vs tank?

Asked by: David C
There is no separate adjustment for the amount of water going in to the bowl, thats really set by the geometry/size of you tank, if you want less water to go in to the bowl then set the tank level lower.

Can 400A be used to replace fill valve in Uberhaus top dual flush 4/6 liter?

Asked by: Steve 88
Hello, I am not familiar with that model, but I can tell you that if the existing valve is fixed through a hole in the bottom of the water tank, and there is an overflow pipe in the tank, then I think there should be no problem. The new valve is fixed in the water tank by a nut on the outside of the tank, that is threaded on the pipe that aptitudes through the tank. I think you will have no problems. Make sure you read the instructions carefully, they can be a little confusing, but look closely at the pictures and I am sure you will have no trouble, especially if you need to adjust the height of the valve.
