PUMP NON-AUTO RULE 12V 500 GPH (RU25D) by Recmar. It is a high-quality non-automatic rule pump. These pumps are marine water pumps that can be found on both large and small ships. They are in charge of removing water from bilge wells and throwing it overboard. It's impossible to stop water and oil from collecting in your bilge wells (bottom part of a boat). Even if your boat is supposed to have a hole, the fitting in that hole can fail. If this happens, your boat may fill with water. Your vessel may sink if you do not have a bilge pump on board. Because the bilge collects water, a bilge pump will remove it. It will be done through the use of pressure or suction. Your boat will be flooded if it does not have a working bilge pump. Furthermore, if your bilge pumps are not maintained, the bilge water can become dirty and polluted. Key Features: The pump and switch are separate items.
