The relief tube runs from the relief valve down into that space so the air has somewhere to go when you open the valve. It is a small piece of plastic doing a job you only notice when it stops working: the valve opens, water comes out, and the tank still holds air.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCheck your model\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThis tube is shown in the parts diagrams for the Super Star Clear C-2000 through C-5500 series and for the SwimClear cartridge filters.
