Marine Shower Drain Pumps
Make sure you and your passengers shower with a drain pump offering peak performance in all conditions. Effectively a sump pump for shower enclosures, these automatic pumps switch on when they contact water or the water reaches a certain level. They’re designed to handle gray water and waste, safely transferring them to a holding tank for disposal. Many of these pumps can also be used to drain sinks, cockpits, live wells, decks and even bilges.
Upgrade offshore bathrooms with a boat shower sump pump from a leading manufacturer like Rule Pumps, JABSCO, Whale or Johnson Pump. You can get 12V or 24V marine shower pumps with an assortment of flow rates based on how much water you need to drain. Marine Parts Source also has service parts and accessories you may need, including sleeve kits for regular maintenance and check valves that stop backflow.
