Its Gulper valves clear the stuff that jams other pumps, and it'll run dry without burning out. Compact enough to tuck into a locker, it's a proven fix for a slow-draining shower sump.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eShower sumps are where a lot of boats fight a losing battle. Hair, soap gel, sand off your feet, and the odd bit of grit all end up in the grey water, and most pumps choke on exactly that. The Whale Gulper 220 was built for this job. It's a 24-volt diaphragm pump that moves shower and sink waste at up to 14 liters (3.7 US gallons) a minute, and it does it without a filter you have to remember to clean.\u003c\/p\u003e\n\u003cp\u003eThe trick is Whale's Gulper valve design. Instead of a tight impeller or a screened intake that clogs, the 220 uses large, virtually non-choke valves and a single large diaphragm that let hair and debris pass straight through. There's no filter to service and no screen to unblock, which is the part boat owners actually notice after a season of use. A double outlet valve keeps flow moving in one direction so the sump empties instead of gurgling back on itself.\u003c\/p\u003e\n\u003cp\u003eBecause it's a diaphragm pump, the 220 will run dry without cooking itself. That matters in a shower sump, where the float or switch often calls for the pump before there's much water in the tray, so it ends up pumping a mix of air and water for the first few seconds of every cycle. Whale rates it to self-prime up to 3 meters (10 feet), so you can mount it above the waterline and still pull waste up from a low sump or bilge tray.\u003c\/p\u003e\n\u003cp\u003eInstallation is where the 220 earns its keep on a tight boat. The body is compact, the pump head is multi-directional, and Whale designed it to sit almost anywhere, including the cramped lockers and lazarettes where these pumps usually live. Most installers mount it with the inlet low and the pump close to vertical so air doesn't lock the line on long grey water runs. It takes 3\/4-inch hose on both ports, and the smart move is to double-clamp each barb so you're not chasing a weep at the fitting later.\u003c\/p\u003e\n\u003cp\u003eElectrically it's easy to live with. The 24-volt DC motor pulls around 1.75 amps in normal running, so it's a light load on a house bank, and Whale specs a 2.5-amp fuse for protection. Wire it through a proper switch or an automatic level sensor and it'll cycle on demand without much fuss. Low power draw also means less heat, which is part of why the diaphragm and valves last as long as they do.\u003c\/p\u003e\n\u003cp\u003eThe materials are chosen for a wet, salty life. The body is aluminum and glass-filled nylon, the valves are nitrile, and the diaphragm is Santoprene, so nothing in the wetted path is going to mind grey water day in and day out. It measures roughly 10-3\/4 inches long by 4-5\/8 inches wide by 6-13\/16 inches tall, so measure your locker before you commit to a spot.\u003c\/p\u003e\n\u003cp\u003eWho's this for? Cruisers and liveaboards with a shower that drains slowly, anyone replacing a tired sump pump that keeps clogging on hair, and builders plumbing a new grey water system that has to run reliably far from a dockside repair. On 35 to 40 foot monohulls the pump can be heard when it runs, so a lot of owners set it on rubber mounts and wire a remote switch at the sump. None of that is required, but it's the kind of detail that turns a good install into one you forget about.\u003c\/p\u003e\n\u003cp\u003eA couple of honest notes. This is a grey water and shower waste pump, not a toilet macerator, so keep it on sink, shower, and drainage duty. And like any diaphragm pump handling hair, the valves will eventually want a look. Most owners pull and rinse the check valves once a year and get many seasons out of the pump. For a filterless, dry-running fix to a slow shower drain, the Gulper 220 is about as proven as it gets.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul class=\"nvn-features\"\u003e\n  \u003cli\u003eGulper non-choke valves and a single large diaphragm pass hair, gel, and debris without a filter to clean\u003c\/li\u003e\n  \u003cli\u003eUp to 14 L\/min (3.7 US gal\/min) flow clears a shower sump quickly\u003c\/li\u003e\n  \u003cli\u003eRuns dry without damage and pumps a mix of air and water at the start of each cycle\u003c\/li\u003e\n  \u003cli\u003eSelf-priming up to 3 m (10 ft) so it can mount above a low sump or bilge tray\u003c\/li\u003e\n  \u003cli\u003e24V DC motor draws about 1.75 A for a light load on the house bank, protected by a 2.5 A fuse\u003c\/li\u003e\n  \u003cli\u003eMulti-directional pump head fits confined lockers and lazarettes and mounts almost anywhere\u003c\/li\u003e\n  \u003cli\u003e3\/4-inch hose ports with a double-outlet valve for continuous one-way flow\u003c\/li\u003e\n  \u003cli\u003eAluminum and glass-filled nylon body, nitrile valves, and Santoprene diaphragm stand up to grey water\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cdiv class=\"nvn-trust\"\u003e\n  \u003ch2\u003eWhy Buy from NVN Marine\u003c\/h2\u003e\n  \u003cul\u003e\n    \u003cli\u003eAuthorized Whale Marine reseller, full manufacturer warranty\u003c\/li\u003e\n    \u003cli\u003eNMEA member and ABYC certified, advice from real boat techs\u003c\/li\u003e\n    \u003cli\u003eSame-day shipping before 3 PM ET on in-stock items\u003c\/li\u003e\n    \u003cli\u003eNY headquarters and Fort Lauderdale flagship retail store\u003c\/li\u003e\n  \u003c\/ul\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cdiv class=\"nvn-faq\"\u003e\n  \u003cdetails\u003e\n    \u003csummary\u003eWhat does the Whale Gulper 220 pump?\u003c\/summary\u003e\n    \u003cp\u003eIt moves grey and shower waste water, including hair, soap gel, and debris, at up to 14 liters (3.7 US gallons) per minute.
