These ATIE assemblies are built to match Pentair P\/N 270056 form and fit and come with the common seals, O-rings, spacer rings and knobs needed for a straightforward swap on compatible 2\"–2.5\" CPVC and PVC diverter valves.\u003c\/p\u003e\n\n\u003ch3\u003eHow do I know this diverter fits my Pentair valve?\u003c\/h3\u003e\n\u003cp\u003eThere are two distinct Pentair diverter sizes: P\/N 270056 for 2\" valves and P\/N 270075 for 1.5\" valves.
