The internal is the moving part: it rises with water pressure, sweeps debris toward the main drain and drops back down when the valve sends water to the next zone. The housing outlasts several internals.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eVenturi and non-venturi\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe G2 range is built in both configurations. This one is the non-venturi internal. The two are not interchangeable in the way a system was designed, so replace like for like and check the part number on what you pull out before ordering.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eSymptoms of a worn internal\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eHeads that no longer rotate, that stop popping up, or that stay proud of the floor permanently have worn where the mechanism indexes.
