Hunter e36 • Waste and Sanitation Systems10.1.2 Overboard DischargeSome discharges have valves associated with them. TheBlack water, or Raw sewage system from the head is onesuch system. Located near the macerator pump (Fig.10.5) (discussed later in this section), is the OverboardDischarge Valve. This is a ball type valve in which thechopped solid waste from the holding tanks is disposedof after passing through the macerator.Basically, all pumps are somewhat associated with theWaste / Sanitation system, but in this section we willfocus on the pumps that are directly associated with theprocess of pumping waste overboard. The supply functionof these pumps are discussed in other sections.Note: The Overboard Discharge Valve should remain closed atall times except when in use.Should the water level rise above the high water mark,and the emergency bilge pump comes online, you willhear a high water alarm from the helm along with a solidred light. It would also be important to mention here thatwhen you hear the high water alarm (Fig. 10.3), it meansthat high water exists in the bilges and it is time to takeaction. Refer to the “Chapman’s Piloting, Seamanshipand Boat Handling.” We have supplied you with a copyof this book aboard your new boat, but if you do not haveone, it is a wise idea to purchase this boating manual. Itis full of useful safety and navigational information.PumpFloat Switch10.2 PumpsProbably the most important pump system on your boatis the bilge pump system. Your boat is supplied with onebilge pump and one high velocity emergency bilge pump.All are part of the Gray water system. This emergencybilge pump has the pumping capacity of 33 gallons aminute from your bilges. Your other bilge pumps varyaccording to boat model and size, please refer to thedocumentation for your bilge pumps for the pumpingcapacities.We are concerned about your safety. You should reviewall information contained in this manual, as well as, themanufacturer’s manuals concerning all systems on yourboat, but the bilge pump system will be one that is crucialto learn. These pumps have the function of clearing waterfrom the bilges of your boat. You must ensure that theyare kept clean and functional in order for these pumps tocomplete that task.10.2.1 Emergency Bilge Pump (Optional)The emergency, or High Water Bilge pump, is generallylocated in the center bilge compartment of your boat. Itis mounted about 12” off the bottom of the bilge. This iswhy it is referred to as a High Water Pump. We discussedin the DC Electric section about the float switch andthe operation of the pump, so, you already understandthat the water level has to be above a high water levelto operate this pump. Fig. 10.2 gives you a look at theemergency bilge pump aboard your boat.Check your Mechanical Arrangement illustration in theBoating Safety Section for the location, and the Waste/ Sanitation illustration at the end of this section, for thedischarge hose routing for this or any pump.10.2.2 The Main Bilge PumpThis pump is located in the lowest parts of the bilge.The function of this pump is to clear the water before itreaches the high water level.Careful maintenance should be made to these systemsto ensure they are always operational. Check the DCElectric Section, or the Operation and Maintenancesubject of this section, to find the details about operationof these pumps and the details of how to manually runthem.10.2.3 Shower SumpFig.10.2Due to the level of the shower drain, we have installeda pump system to rid the boat of water from your shower.The small filter also acts as a collection point for hair andother waste materials that might get washed down the10.3
