Claim 12:
13. A system for keeping a fill pump primed between intermittent operations of the fill pump and for dissolving gasses in water sourced by the fill pump from a body of water located below a container, the system comprising:
(a) a water intake assembly for the fill pump, the water intake assembly having a first check valve, wherein water flows through the first check valve into the fill pump;
(b) a pump output assembly having a second check valve and an output conduit or chamber comprising a water outlet, wherein water flowing out of the fill pump through the second check valve creates a pressure differential and turbulence in the output conduit or chamber; and
(c) a gas delivery system comprising a gas line through which a gas is introduced to the pump output assembly, wherein the gas line is in communication with an air port and water flow through the second check valve draws ambient air through the air port into the output conduit or chamber and dissolves the gas in the water;
wherein gas-saturated water is released through the water outlet into the container; and
wherein the first and second check valves keep the fill pump primed after the fill pump ceases pumping.
