## Description

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

Review: ⭐️⭐️Fixed My Running Toilet Instantly – Quiet & Reliable!⭐️⭐️ - I don’t usually write reviews, but this one definitely deserves it. My toilet had been running on and off for weeks, and it was starting to drive me crazy (not to mention the water bill). I decided to give the Fluidmaster 400H Performax a try, and I’m really glad I did. Installation was surprisingly easy. I’m not a plumber by any means, but the instructions were clear and everything fit perfectly. Took me maybe 10–15 minutes from start to finish. The adjustable height feature made it simple to dial in the right fit for my tank. The difference was immediate. The fill is much quieter than the old valve, and it shuts off clean without that annoying trickling sound. The water level is now consistent, and the toilet refills quickly without being loud or aggressive. It also feels like a solid, well-made piece—nothing cheap or flimsy about it. You can tell it’s built to last. If you’ve got a running toilet or an old fill valve, just replace it with this and save yourself the headache. For the price, it’s a no-brainer.
Review: Easy and Effective Replacement - Easy to install. Works great. I am so relieved to finally have it QUIET in the bathroom; the old valve was slow and just ran and ran and ran. This wasn't expensive; it is adjustable. And there are instructions in both print and video form.

## Questions & Answers

**Q: What is the difference between the 400H and 400AH?**
A: The 400H is the newer version of the 400AH. The bowl water adjustment on the 400H is integrated into a knob in at the top of the flush valve. On the 400AH, a roller on the refill tube adjusts the bowl water level.

**Q: Can i use this to replace a delta toilet fill valvepart RP71188?**
A: The 400H-002 will replace the Delta model. The 400H can adjust to the same height and comes with an adjustable bowl refill knob to control the amount of water going to bowl. With this adjustment you should be able to match both bowl and tank water levels to the original levels.

### ⭐⭐⭐⭐⭐ God Is Good—Fixed My Running Toilet in 15 Minutes!
*by Y***A on January 30, 2026*

God is so good! 🙌 This product and this company are absolutely awesome. I’ll be honest—it only took me about 15 minutes to replace my toilet fill valve. I had the part for a while but kept putting it off. I was so tired of the toilet running nonstop and constantly having to take the lid off to adjust it. Finally, I said, “That’s it—I’m fixing this today.” I even got instructions from ChatGPT beforehand, but honestly, I didn’t need them because the instruction booklet included with this product is excellent—clear, simple, and very easy to follow. I did run into one small challenge: the rubber hose in my toilet is permanently attached to the main nozzle and wouldn’t come off. I called the company for guidance, and their tech support was incredibly friendly and helpful. He told me to take the hose off of their toilet fill valve and just connect it to the nozzle in my toilet. I told him that I had been trying to do that, but it wouldn’t come off. So he told me to place their hose in hot water, and it came right off—problem solved! I was then able to install everything with no issues. Why pay $200 for a plumber when you can do it yourself? This cost me around $15, took about 15 minutes, and works perfectly. I’m so happy with this purchase and truly impressed with both the product and the customer service. Highly recommend!
