It combines the pump and automatic switch in one body, which keeps installation simpler in tight bilge spaces and avoids the extra footprint of a separate float switch.\u003c\/p\u003e\u003cp\u003eThis is a practical fit for boats that need unattended bilge water removal while sitting at the dock, on a mooring, or between trips.

It also works well as a secondary automatic pump in a stepped bilge, fish box sump, or other low point where you want backup water removal without adding another float switch.\u003c\/p\u003e\u003ch6\u003eUse on board\u003c\/h6\u003e\u003cp\u003eIt suits owners who want a simple automatic bilge pump for runabouts, small center consoles, aluminum fishing boats, and sailboats with a modest bilge area. On larger boats, it is more often used as a secondary pump or for a smaller compartment rather than the main high-capacity bilge circuit.\u003c\/p\u003e\n\u003cspan itemprop=\"mpn\" hidden\u003e4505-7\u003c\/span\u003e","brand":"Attwood Marine","offers":[{"title":"Default Title","offer_id":53721546064053,"sku":"QBP398552","price":94.82,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0977\/8171\/1029\/files\/1322147_qbp398552.webp?v=1794117769"},{"product_id":"qbp494890","title":"Whale BP2552B Gulper Toilet Pump - 12V BP2552B","description":"\u003cb\u003eBP2552B Gulper Toilet Pump - 12V\u003c\/b\u003e\u003cbr\u003e\u003cbr\u003eTrust Whale to bring you quality products every time.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003cbr\u003e\u003cul\u003e\n\u003cli\u003eFor holding tanks and vacuum systems\u003c\/li\u003e\n\u003cli\u003eVirtually unblockable and self-priming up to 9.8'\u003c\/li\u003e\n\u003cli\u003eCan be mounted in most convenient part of boat\u003c\/li\u003e\n\u003cli\u003eEasy to maintain and can run dry without damage\u003c\/li\u003e\n\u003cli\u003ePumps macerated waste\u003c\/li\u003e\n\u003cli\u003eFuse size 15-amp automotive output (open flow) 4-3\/4 gal per minute\u003c\/li\u003e\n\u003cli\u003eWire size of 16 AWG\u003c\/li\u003e\n\u003cli\u003eMax head and lift is 9.8'\u003c\/li\u003e\n\u003cli\u003eHose connections are 1-1\/2\"\u003c\/li\u003e\n\u003cli\u003ePorts: 1-1\/2\"\u003c\/li\u003e\n\u003cli\u003eVolts: 12\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cimg src=\"https:\/\/productimageserver.com\/prop65\/6pt.png\" alt=\"Warning\"\u003e\u003cstrong\u003eWARNING:\u003c\/strong\u003e This product can expose you to chemicals which are known to the State of California to cause cancer, birth defects or other reproductive harm.
