The bleed tube is the path that air takes to reach the relief valve on the lid. Open the valve, the air goes up the tube and out, water follows, and the filter is purged. Without an intact tube, you can hold the relief valve open all day and still have air trapped in the tank.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eModel coverage\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe part is named for the PTM50 and PTM70.
