A variable speed swim spa system wherein the user can choose between a combination of speeds with two or more pumps connected through a manifold to one or more swim jets. Check valves are used on all but the first pump to prevent backflow of water effluent and can be placed inside the manifold or between the pumps and the manifold. A user interface attached to electronic controls and operating software allow the user to program his preferred speeds with the one more jets using the two or more pumps.
