A: The proper size cable to use in between your controller and the pump depends on the What type of water pump do you plan to use and the distance you need to run the wire. The size of the pump's discharge pipe depends on what type of pump you plan to use, the distance from the pump to the tank and the GPM flow rate that the pump will produce. The smaller the pipe is the higher the friction loss which makes your pump work harder to produce less water.
