Review on 💧 Kohler GP77006-RP Ceramic Valve: Enhanced Performance and Durability, Rough Plate Design - One Size by Matthew Sutton

They worked great in my dripping Kohler spa faucet. The biggest challenge was figuring out what size to buy and then removing the old one. For about a week I tried spraying the old WD40 and then PB Blaster every day. None of them worked well enough to loosen the bolt. My friend had a much larger ratchet than mine I borrowed and it worked, probably because I could get a lot more leverage with a longer handle. Next time I would even try inserting the end of my little ratchet into the tube to lengthen it. In this photo you can see my much smaller ratchet next to a grandpa sized ratchet I borrowed and it did the trick.
