Review on 🔧 Enhance Performance with Essential Values Pressure Balanced Cartridge #9740420 - Superior Aftermarket Replacement Sub Assembly for Pfister 0X8/JX8/VB8/JV8 Deep Casting Valves by Andrew Mack

When I received the valve it looked like a great replacement. The quality looked good and it looked like the original but a lot simpler. I was very impressed. When I installed it, it leaked through the middle when I turned it on. Desperate, I took it apart and found that the small o-ring in the center was misplaced and stuck in front of the valve. Luckily I was able to move it to the right place and reassemble the valve. After reinstalling the valve it worked fine and I was very happy with it. I'm pretty sure this should have happened during the original build.
