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

Fits well but the old one was brass and copper. It appears to be chrome steel or maybe stainless steel. I replaced the fixed rotating block with this one, then soaked the old block in vinegar overnight before disassembling it, and soaked the parts in vinegar again to remove the calcium from the innards. Lubricated with pool grease and reassembled. I'll keep it on hand to replace the next one that gets too hard to spin. To restore, remove the clamp and butterfly stopper from the top, remove the washer from the bottom, and push the top down through the base. But if you don't have the extra time for it, it's cheap enough to just buy a new one next time. When replacing, use Teflon tape for easier removal next time. As others have pointed out, it doesn't matter which site you buy. The only difference between hot and cold is a small, bow-tie-like latch at the top that fastens with a clip. If you want to change it, pull the clip and rotate the stopper 90 degrees. The photos show an old reconditioned one to show the clip and stopper.
