Eliminate bulky gray water sump boxes with associated odor and prone-to-failure mechanical switches with this high-capacity gray water pump and your choice of “intelligent” control options. Outstanding pump features include ports that rotate 360° for easy installation and water-tight Deutsch® connectors. For a dedicated shower discharge pump, select the Large Gully IC-a compact “intelligent” shower drain with built in electronic, water-sensing switch. For multiple gray water sources, select the Two-Way Manifold IC-which also activates the pump via a built-in, solid state, electronic water sensing switch. Both options include a “soft-start/stop” function for gentle pump activation and long pump life.

Comments about Whale Pumps Gulper IC Gray Water Systems:

The shower pan in our head sits just inches off of the bottom of the boat and there is no room for a typical shower sump. This has been installed for about 6 months now and has seen some heavy use. It does not pump at a high rate but does keep up pretty well with the shower. The auto on and off works reliably. It is a little noisy but since it only runs when the shower is being used that isn't really an issue. This was a simple installation and seemed like the only easy solution to our particular shower sump needs.
