Thanks Pelagic. So the rule dual port 800gph will supply waterto the livewell tank? Then the lower port of the rule dual port add another pump correct?You’ll need two pumps- with the Rule dual port, only the top port is on the discharge side of the pump. Think of the lower port as a built in tee fitting- it just allows you to pull water for another pump from the suction side of the livewell pump, without having to install an additional tee fitting.
You will need to have a washdown pump as well, which is a different type of pump designed for low flow, high pressure as opposed to the livewell pump’s high flow, low pressure. The washdown pump will pull suction from the lower port of the dual port pump.
Any recommendations for the washdown pump? I have the shurflo blaster II whichbis probably the one installed since the boat was built in 2015.
