When the handle cracks, develops play in the shaft, or no longer seats cleanly at each position, mode selection becomes unreliable. This OEM replacement restores precise, positive operation across all valve positions.\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eValve Size\u003c\/td\u003e\n\u003ctd\u003e1.5\" (1-1\/2\")\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaterial\u003c\/td\u003e\n\u003ctd\u003eNylon handle with stainless steel internal linkage\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCompatibility\u003c\/td\u003e\n\u003ctd\u003eUltima II series filters with 6-port or multi-port valve assemblies\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eIncludes\u003c\/td\u003e\n\u003ctd\u003eHandle and full internal linkage assembly\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ch3\u003eInstallation\u003c\/h3\u003e\n\u003cp\u003eClose the main drain valve and confirm no water pressure remains in the system. Remove the mounting bolt (typically a 1\/4\" socket head cap screw) from the valve body. Slide the old handle assembly off the shaft. Align the new assembly onto the shaft so the keyway seats fully into the matching slot.
