750 GPH 12V Automatic Shower Sump Pump System
Multi-Port Grey Water Drainage for Boats, RVs & Caravans
Keep your boat or recreational vehicle dry and odour-free with this 750 GPH 12V Shower Sump and Pump System. This multi-inlet grey water sump collects water from showers, sinks and other grey water points and pumps it overboard or into a holding tank. It can handle waste water from more than one tapping point.
The fully submersible pump has a built-in internal float switch, so it switches on automatically as the water level rises and off once drained. A check valve on the outlet stops water flowing back into the sump box, while the clear clip-on cover with gasket prevents splashing and odours. An easy-to-clean mesh filter collects hair, sludge and debris.
