Made from UV‑stabilized plastic and sized for common hose and pipe fittings, it fits cutouts about 5 3\/4\" by 3 3\/4\" and provides an air‑vent connection and screened opening to help prevent debris entry.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this inlet let me use both gravity fill and city water?\u003c\/h3\u003e\n\u003cp\u003eThe unit features two distinct ports: a large gravity fill opening that accepts 1 1\/4\" to 1 3\/8\" ID hose and a threaded city water inlet for a 1\/2\" pipe fitting.
