Review on Kohler 1131481 Hot Ultraglide Valve Assembly: Efficient and Durable Metallic Concealed Valve Solution by Andrew Britton

Bought to replace a valve in a faucet that after 19 years of service had started to drip constantly and the original valve cartridge was so stuck I had no choice but to replace the entire valve assembly. It was the perfect replacement. The faucet cap and handle easily attach to the new valve body. It took a few tries to place the valve bodies and align the handle correctly, but I think it's fine for any replacement like this. The knobs are incredibly smooth now (better than I can ever remember how the original valves worked - I replaced both the hot and cold valves). I highly recommend this product. Two notes: one of the other reviewers suggested getting a pool key from General, which I totally agree with (if you're doing the replacement yourself), and you'll probably want to replace the water supply hoses too - I ran out and buy these in the middle of the project .
