Pro Tip: 1-421JKABNF
If your faucet is dripping from the spout even when the handle is turned off, a worn seat washer is the most likely culprit. The 1-421JKABNF is specifically designed for high-heat scenarios where standard rubber washers might soften or fail prematurely. For a complete "factory-fresh" feel, we recommend inspecting your valve seat for pits or scratches while you have the cartridge removed. Need technical advice? Call ProDryers at 888-503-7937!
