Fluidmaster 400H-002 Performax Universal Toilet Fill Valve High Performance Tank and Bowl Water Control, 1-Pack, Multicolor

I’m seriously impressed with this fill valve. My toilet was running nonstop and it was driving me crazy, so I decided to give this a try, and WOW. I installed it myself in literally 10 minutes with zero plumbing experience!The instructions were super simple, and everything fit perfectly. The seal is super solid—no leaks at all—and now my toilet runs so smoothly. The waterflow is noticeably more efficient, and it fills the tank way faster than my old valve. No more waiting forever after flushing!What I really love is the adjustment capability. You can fine-tune the water level and flow so easily with just a twist, which is super helpful if you’re trying to save water or just get your toilet to behave properly. The overall design is sleek, compact, and doesn’t take up too much space in the tank.If your toilet’s acting up, this is seriously a lifesaver. Affordable, effective, easy to install, and totally beginner-friendly. I feel like a DIY queen for fixing it myself 💪🚽💧

Took minutes to install. Very easy with basic home tools. Works so much better than the older valve. Quiet too, and I think it's saving me more water and money on the bill.

Yup. it is a replacement toilet tank valve. Surprisingly easy installation. Worked first time. I was surprised and delighted that there was an adjustment knob for how much flow went back to the bowl. nice to have adjustment, as we have very high water pressure, and didnt need full blast to fill the bowl back up.

This fit my older Gerber perfectly. It took about 5 minutes to get it installed and there were no issues. Basically just take out the old, put this in its place and screw it in the secure. It can be height adjusted as well as neededThe only gripe is that it can be loud when refilling. Nothing you can't get past, it's not so bad that it is a deal breaker. Just a minute of hearing the fill and then quiet again.

This fill valve fixed my noisy, slow toilet in minutes. Installation was quick, and the adjustable flow settings are a nice touch. It’s much quieter than the original part and fills the tank quickly. Great product for a simple upgrade or repair.

I 17 year old put these up in 5 minutes in each bathroom. I had so many problems with the last product which were a different brand. The water would shoot up onto the wall out the back of the toilet top and the mechanism would the floater device would hit the other pipe and if you'd move it then you get spraying water again up the wall. And the other bathroom would make a loud squealing noise every time you flush. I am in heaven right now they're both working perfectly with the new product there's no leaking there's no noise, absolutely perfect!

Installation was easy and straightforward! No leaks, at all, and my toilet has stopped running! There are two ways to adjust the float, with one of the ways being to adjust the height at the main stem. There is, fortunately, a second way to fine tune the float, just in case you were slightly off in setting the height of the stem. This is a great feature, or otherwise I would have had to take the time to adjust the height at the stem, which would be time-consuming.A great design! Very well thought out!

Easy install, good price. No need to pay a plumber on this one. You can do it. Follow the instructions, and it is like baking a cake. Pay attention to the directions to spin the nuts off. It will save you some trouble. I had to use my channel locks on the water line to loosen because it was very tight. YT has a 3.5 minute video on installing this model, if a video helps you. Pull the restrictor plug from the bottom of the tube before installing. Needle nose pliers will grab it easily, and it slides right out. Your tank will fill faster and you don't need it. I don't know why they put a water restrictor in since the tank and bowl is going to fill to the adjusted levels anyway. Probably, just another useless government regulation. You can adjust the tank and bowl water. More water in the tank gives a better flush. I also marked my bowl water level with a pencil before starting. This saves a step of pouring water in your bowl after you have drained it. More water in the bowl also gives a more powerful flush. The pencil mark is easy to remove with some tissue. Quick and easy installation. 7 year warranty on this product.
