The serial number on the pump label is what tells you which side of that change your pump is on. This part is the one for pumps after PB120111001.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat it is for\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe drain plug is how water gets out of the pump volute. It matters most at closing, when a housing left full of water can freeze and crack. It is also the part most often lost, because it comes out once a year and gets set down somewhere.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eThe o-ring is the seal\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eA booster pump that weeps at the drain plug is almost never a cracked housing.
