Chlorine gas attacks the plastic from below and UV works on it from above. Threads seize, the plastic crazes, and eventually the lid will not seal no matter how hard it is tightened.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat you get\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003ePentair supplies this as the complete lid assembly rather than as separate pieces, so the parts arrive matched to each other and to the feeder body.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhile the feeder is open\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe lock ring and the lid o-ring are separate Rainbow parts.
