Check Valve With Override

A check valve with over-ride comprising:

• a housing containing an outlet and a poppet above a valve seat;
• said housing having a lower section below the valve seat with at least one inlet opening;
• and
• a foot extending from the poppet through the lower section to below a lower portion of the lower section;
• wherein at least one of gravity and fluid above the poppet assist in sealing the poppet to the valve seat in a check valve configuration when pressure at the outlet is greater than pressure at the at least one inlet opening in the check valve configuration;
• a flow configuration where pressure at the outlet is less than pressure at the at least one inlet opening thereby at least assisting in pulling the poppet upwardly off of the valve seat for fluid flow to proceed from the at least one inlet opening through the valve seat and out the outlet;
• and
• an over-ride configuration where the foot contacts a surface below the lower portion of the housing thereby pushing the poppet upwardly off the valve seat permitting fluid to pass from a direction of the outlet through the at least one inlet opening when pressure at the at least one inlet opening is less than pressure at the outlet.
