Any pool configuration has two basic piping systems: suction and return. The suction side consists of all the pipes coming from the pool to the pool pump. In a basic system these include the pipes from the main drain and the skimmers. The return or discharge side consists of all pipes going from the pool pump back to the pool. In a basic system these include lines to multiple pool jets. On the suction side you will want to be able to control the flow of water coming from either the skimmers or the main drain. This is done with a diverter valve. This page will provide a step by step process for installing a diverter valve on the suction side of the pump.
