Review: Solid Upgrade – Easy Install Once You Get the Old One Off - I recently installed the Fluidmaster 400H-5003 Performax Universal Toilet Fill Valve, and it worked great. My toilet was noisy and slow to refill, and this fixed both problems right away. The whole job took me about 20 minutes. But to be honest, most of that time was spent wrestling with the old valve stem. The lock nut on the original valve stem was corroded and took some real effort to remove (make sure you have a hammer and a slot-head screwdriver handy to break the old one). Once that was off, installing the new Fluidmaster assembly was quick and painless. The instructions were clear, and I didn’t need any special tools. After installation, the toilet filled much faster and ran noticeably quieter. I also appreciated being able to adjust the water levels in both the tank and the bowl to get the flush just right. It’s not completely silent while refilling, but the sound is much quieter than before and not a problem at all. Overall, this is a great product that’s easy to install and works exactly as expected. If your toilet’s making noise or slow to fill, this is a reliable and affordable fix.
Review: Quality toilet fill valve - Extremely easy to install arrived quickly after order and have no leaks in either water closet. This is a universal fit and adjustable for tank volume. Good value

## 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.
