### ⭐⭐⭐⭐⭐ RV water valve kit
*by K***V on January 11, 2026*

Good fit, and works well.

### ⭐⭐⭐⭐⭐ Good replacement valve, no leaks
*by K***I on August 27, 2025*

This is a good replacement valve for an RV toilet that was leaking. We accidentally broke one of the tabs while installing it, but with the screws securely tightened, it still works great. Replacing these is not easy when the toilet is placed in a spot where the back is not very accessible. Having now done it once though, it will hopefully be easier next time. I plan to order the 2 pack next time so that I have extras on hand, just in case. It's not that I think this product is faulty, but these valves tend to need replacing as general practice. It will be nice to have extras so that I don't have to turn off all water in the trailer if the new one starts leaking. I am pleased with this valve.
