Review: God Is Good—Fixed My Running Toilet in 15 Minutes! - 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!
Review: Great price and great functionality. - So far this has fixed my water running problem. It was easy to install, easy to adjust and it’s very quiet while operating. These are the only products I use to repair toilets. I have gotten a couple that didn’t stop the water running issue but that’s few and far between and they have been replaced without issues. It just sucks to have to do all that work over again. I still recommend these for their price and longevity.

## 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.

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.
