ABSTRACT:
A self-priming drain guard siphon insertable into the opening of any reservoir drain subjected to accumulation of fluid transported debris comprising an outer shell (17) enclosing an inner priming chamber (20) held upright on the bottom of a reservoir by support tabs (18). Priming chamber (20) is comprised of inlet openings (22), a horizontal chamber (20a), a vertical chamber (20b), and an outlet opening (24). Inlet openings (22) are each positioned above and between adjacent support tabs (18) and vertical chamber (20b) at an elevation slightly higher than the bottom of a reservoir. Inlet openings (22) are cumulatively sized to approximate flow capacity of horizontal chamber (20a) and are positioned on the underside of horizontal chamber 20a to prevent lateral passage and direct contact with median sized debris. Horizontal chamber 20a is sized to approximate the flow capacity of vertical chamber 20b. The overall length of horizontal chamber (20a) is predetermined to accommodate inlet openings (22), vertical chamber (20b), and to bridge across the reservoir drain opening. Vertical chamber 20b is sized to approximate the flow capacity of the reservoir drain opening. Horizontal chamber (20a) communicates directly with vertical chamber (20b) to form a fluid transmitting conduit which self-primes with rising fluid elevation. Airless flow develops within priming chamber (20) when outer shell (17) becomes submerged.
