Review on 🚿 GP500520 Pressure Balancing Unit Cartridge Replacement for Kohler Shower Valve, Compatible with Rite-Temp Bath and Shower 1/2" Single Handle Valves by Brian Cheney

I ordered this part from Revain because I needed it right now. You can buy it on ebay for €10. This comes with o-rings for different shower enclosure models. I have Koehler Forte. I think the model is 304. It also comes with a big one to seal the mixing valve in that valve. Silicone grease is also included. Installation is a matter of 10 minutes. This will eliminate leaks from the shower enclosure. In my case it also made the shower much quieter. Turn on the water again for a few seconds while the shower body is disassembled. This will remove any debris in your pipes that could be clogging the valve and restricting water flow.
